How do you coordinate a group of scientists working across seven continents, to achieve the project objectives? By Virginia Hannah

This is my role and although it might sound easy, it really isn’t!!

My name is Virginia Hannah.  I have worked at the BGS for over 15 years starting out as a Secretary, later known as Business Assistant. More recently, I have become a Project Coordinator, working on various science projects within the Informatics Directorate.  I now coordinate and bring together the practical and necessary elements of the projects, which a scientist may not always think about, enabling the effective delivery of their science.

I am also the Secretariat for the OneGeology Project, which is still a very active project within BGS and stakeholders from around the globe.  The mission is:

to make web-accessible the best available geological and other geoscience data worldwide at the best possible scales, starting with at least 1:1 million scale.

OneGeology Board members at the 16th Meeting in Vancouver, Canada, June 2018
The project, governed by the Board, meet virtually several times a year and is chaired currently by James Johnson, the CEO of GeoScience Australia (GSA).  I manage the logistics of these meetings that stretch over many different time zones.  This usually means I end up upsetting at least one member who has to attend at an ungodly hour!  However, I try to make this fair and give everyone the chance to attend at least one meeting wearing pyjamas ūüėĄ  

There is also one face-to-face meeting annually, which the Board Members take in turns to host in their own country, but again, it is my role to coordinate.  I spend lots of time liaising with science and administration staff, where there is quite often a language barrier to overcome, to manage the usual logistical requirements for the meetings.  In addition to the day programmes, I also organise evening events such as conference dinners; ensuring time for networking, I have to bear jet lag in mind and make sure delegates are not is falling to sleep in their soup!  I also manage the material we need to take with us, such as pop-ups, give-aways, posters etc, and determine how we are going to get that stuff to the venue.  Whether that be filling peoples cases up for them or arranging courier deliveries, which can be a nightmare if you only have a conference venue address to deliver to!

I manage the administration of the project and all of the communications and outreach activities.  I am responsible for purchasing all marketing material as well as creating flyers, posters and creating and editing newsletters.  I attend the meetings to report on marketing progress and expenditure, as well as take notes and detailed actions from the meetings, which I monitor for progress and closure after the meetings.

OneGeology Board Meeting in Full Swing at Geological Survey Vancouver Canada Offices June 2018
This year the Geological survey of Canada (GSC) kindly hosted us at their offices in Vancouver, 13-15 June. OneGeology celebrated its 10-year anniversary in 2017-18, so to celebrate the board decided to make this event in Vancouver bigger and hold a three-day meeting.  So adjacent to the usual one day face-to-face board meeting, we hosted the annual Technical Implementation Group (TIG) meeting and ran a one-day regional workshop, which outlined the focus of the project for the next ten years, with a particular focus on North American involvement.  To manage these events, I worked closely with the team at GSC,  Boyan Brodaric and Sonya Ryou

The invited delegates came from all over the world: UK, Japan and Australia to name a few.  Many people that attended gave presentations, which you can find on the OneGeology website along with the minutes from each event.  

Prior to the meeting, I had to plan the timings of these presentations and work with the IT team to ensure that the rooms that we had been allocated, were equipped with the correct equipment to make the presentations.  During the meeting, I also had to make sure that the presentations were loaded onto the meeting PC and ready to run at the correct time in the agenda. I worked alongside the chair to make sure that the presentations ran to time.

To communicate the considerable achievements of the last ten years, we aligned the OneGeology meetings with the Resources for Future Generations conference, which was being held at the Vancouver Convention Centre.  

Session 4 was The changing roles of geological surveys.  Here, Carina Kemp (GeoScience Australia), Matt Harrison (BGS) and Fran√ßois Robida (BRGM) presented and ran the discussion session about the OneGeology project.  They described how big data is managed within the international geological survey community and explored how exciting new technological directions, such as the application of artificial intelligence, will impact next generation geoscience and the geological survey organisation of the future.  I helped to co-ordinate participation in the session prior to the conference and attended to ensure they ran smoothly.  I also minuted the session and took photographs, which I tweeted from @onegeology and will feature in the next OneGeology Newsletter.

At the conference exhibition, we also had a booth in association with the rest of BGS.  The booth was staffed by BGS personnel attending the conference.  I wanted OneGeology to be represented at the booth, so prepared a timetable for an expert to be available during certain times every day to answer any questions and give advice.  I took a corner of the booth and set it up with OneGeology information and products to entice delegates to take an interest. 

I also work on the H2020 European Plate Observing System (EPOS) project, as the communications lead for the Geo-Energy Test Beds for Low Carbon Energy (GETB) work package.  I also attended the RFG conference in this role to report on presentations given by the GETB teams 
  1. Dr Helen Taylor (BGS) who presented: EPOS and ECCSEL; Geoenergy Test Beds in European Distributed Research Infrastructures
  2. Mohammadreza Jalali from ETH Zurich, who presented; In-situ Stimulation and Circulation Experiment as a Decameter Geo-Energy Test Bed for Enhanced Geothermal System Development presentation, on behalf of EPOS GETB during the same session.  
I attended both presentations to take notes and pictures to communicate to the wider EPOS community through our dedicated GETB web page and to produce an article for the external newsletter, produced by the EPOS programme management office.

Dr Helen Taylor giving the joint EPOS –ECCSEL presentation at the RFG in Vancouver, June 2018
This was the first time I had the chance of attending a conference of this size and it was exciting to have the experience.  It was challenging because I hadn’t experienced a science conference as a delegate before and being a ‘non-scientist’ I found it difficult to know which sessions to attend.  When I did find talks that I wanted to see, they were all over the place, and this convention centre was BIG, so navigation was fun, but I managed it and attended some great sessions.

Attending the conference meant I finally met people face-to-face who I have worked with remotely for years.  I would not necessarily have met them in person otherwise.  It has given me a greater understanding of the need to network and insight into some of the collaborations BGS has going on globally, and the complexity of how these intertwine with other collaborations closer to home.  It has also strengthened my confidence in the work that I do within these collaborative projects and how my role fits into the bigger picture.

As well as this, I got to hang out with a moose and was fortunate enough to see this beautiful view of the Rockies out of the aeroplane window on the way home…if Carling made sunsets!

VIDEO: Landslides Training in Scotland... by Cath Pennington

In October, a few of us spent a week in the beautiful Scottish Highlands looking at landslides and we've made a video about it.  The trip was just after with a period of very heavy rain that triggered some debris flows that closed the A83 Rest And Be Thankful Pass where these types of landslide are a regular occurrence.

Staff attending the training week had a range of different expertise and were mostly from the Landslides Team in Keyworth and Quaternary Geologists from our Edinburgh office. These are two groups of people trained to look at the landscape in different ways.

The idea was for the Landslides Team to get a better understanding of the Scottish geology - a complex beast that can produce different landslides to those elsewhere in the UK - and for the Quaternary Geologists to further their expertise in landslides, especially debris flows.

Debris Flows

These landslides are defined by Ballantyne (2004) as:
the rapid down-slope flow of poorly-sorted debris mixed with water.
Debris flows are a particular problem in Scotland.  Their biggest impact is to cut across roads and railways that can leave communities isolated and important routes blocked.  Perhaps the most famous repeated site of debris flows is the Rest And Be Thankful Pass where the closure of the road results in a 55-mile detour.

Geologist, comparing the debris flows that happened in 2007 with that from October 2018
How we put debris flows on our maps is something we are working on at the moment and this produced a lot of discussion in the field.  We also used the examples we visited to help us consider our GeoSure Debris Flow Model, a map that provides information on the potential of the ground to form a debris flow.

The training course was well received by everyone attending and has opened the door to plenty of collaborative work that can only be beneficial to everyone.  We even came across this: Landslide beer!  It was named after the debris flow that blocked the road near the brewery, but also because of the repeated debris flows on the A83 that leave the brewery cut off.  The initial debris flow is documented in our National Landslide Database (17693/1) as well as many of the others on the Rest and Be Thankful Pass.

Decarbonisation: the importance of ‘good geography’...by Prof Mike Stephenson

On a recent visit to the spectacular Iron Bridge in Telford Shropshire I was reminded not only of the engineering genius that designed it - Thomas Pritchard - but also the factors that came together to make the bridge possible – a gift of good geography and geology. The bridge, opened in 1781, is widely seen as a symbol of the birth of the industrial revolution in the fact that its construction involved the use of raw materials on an industrial scale – limestone, coal and iron ore. Without these three resources in close proximity to the town of Ironbridge and the bridge itself, this famous construction would simply not be there.

The industrial revolution set the world on a course of the large scale of use of resources including fossil fuels and therefore on the course of a period of emissions that could be called ‘carbonisation’. We now need to decarbonise, but for some of the most challenging parts of decarbonisation, for example industry, transport and domestic heating, good geography and good geology will still matter.

We are witnessing rapid progress in the decarbonisation of electricity production with wind and solar costs dropping rapidly. But electricity is the easy area to decarbonise. Industries that make steel, aluminium, cement and ammonia won’t be so easy to decarbonise because the processes they use produce CO2 emissions directly, and because they use very large amounts of fossil fuels and electric power. Domestic heating is also hard to decarbonise. The UK, for example, uses more energy in heating than for generating electricity and for running its transport system. Around 70% of this energy comes from burning gas producing more than a quarter of the UK’s CO2 emissions.

The decarbonisation of industry, transport and domestic heating sectors needs planning and thought. One solution is to develop geographical clusters that can exploit existing industrial infrastructure together with natural geological resources and other advantages to allow local solutions. An example is the hydrogen economy – the idea that hydrogen can provide a fuel for cells to drive vehicles, heat houses and power industry . Its production may in the longer term be through electrolysis of water using excess (renewable) electricity, but in the short term is more likely to be produced by steam methane reforming (SMR) from natural gas which produces CO2 and hydrogen. The latter is a useful zero carbon fuel, and the former can be used or most likely will need to be disposed of geologically. The key point here is that geological disposal of CO2 can’t be done everywhere, because only specific geologies are suitable. It’s also known that to make the hydrogen economy work, huge amounts of the gas will be needed, and therefore so will large local storage. In most cases, this means geological storage in salt. So geography and geology are again important.

An example is the H21 Leeds City Gate project  which seeks to convert the existing natural gas network in Leeds – used mainly for heat -  to 100% hydrogen. A batch of four SMRs on Teeside will produce the hydrogen needed while the waste CO2 will be captured and disposed of offshore in the southern North Sea. Capture is well established and the technology for disposal has been demonstrated at scale for over twenty years close to the Sleipner Gas Field in deep North Sea rocks. Salt cavern storage in the Tees and York areas will be needed for ‘intra-day’ and ‘intra-seasonal’ swings in demand as heating is turned on and off by consumers. Beyond heating, the availability of low-cost bulk hydrogen in a gas network could revolutionise the potential for hydrogen vehicles in the North East and, via fuel cells, support a decentralised model of combined heat and power and localised power generation.

A similar project, the Liverpool-Manchester Hydrogen Cluster, aims not just at decarbonising domestic heat, but also at decarbonising major industrial gas users in the Liverpool-Manchester area, including in the oil refining, glass manufacturing, food and drink, chemicals and pulp and paper sectors. The main use of gas in these industries is for heat production, whether in furnaces, ovens or combined heat and power (CHP) plants.

The Liverpool-Manchester area also has good geology. The nearby Liverpool Bay ‘complex’ of hydrocarbon fields located in the East Irish Sea off the coast of Merseyside, could be repurposed to provide CO2 storage and these fields are likely to cease production around the time that a cluster concept might be reaching maturity. In the early stages the Liverpool-Manchester Hydrogen Cluster does not envisage H storage in salt because many local process industries operate continuously, so little change in demand is forecast daily or annually so there aren’t big fluctuations in demand. However the area is rich in salt deposits which will be well suited for a larger roll out of hydrogen. The area also benefits from two established pipelines that already transport hydrogen, as well as pre-existing skills and capability related to the production, handling and use of hydrogen.

Perhaps most important is the fact that local ‘energy ecologies’ – collections of energy users and producers - are beginning to work together to realise the need to decarbonise. This added to the local funding arrangements of the Government’s new Industrial Strategy  as part of the ‘place agenda’, will provide the impetus to make decarbonisation happen through carefully targeted government funding along with co-funding from industry to address market failure. The cluster concept underlines the need for industry and government to work together to decarbonise, but also the importance of the distribution of useful rocks, and ultimately the importance of geology in decarbonisation. This is alongside the decarbonisation options that rocks also provide, including geothermal power and cooling and air conditioning, as well as the potential for large scale heat and energy storage.

Back in the Eighteenth Century the impetus to build the Iron Bridge came from local entrepreneurs, including Abraham Darby who first smelted local iron ore with coke made from Coalbrookdale coal in 1709. Darby had agreed to construct the bridge with a budget of £3250 and this was raised by sponsors of the project, mostly early industrialists from surrounding towns and villages. The bridge probably cost about twice that - around £700,000 in today’s money. This was an investment that was part of the ‘carbonisation’ process which was the industrial revolution. The same kind of partnerships are being formed in the new decarbonisation clusters again driven by the opportunities that new technologies can bring to local economies.

Feeling the heat: exploring the potential for geothermal energy...by Chris Rochelle

The Los Azufres geothermal area. Steam swirls from a natural vent (fumarole)
in the valley bottom, and also from several geothermal wells amongst
the trees further up the valley sides.

Part One - Mexico


Swirls of steam and the deep ‘bloop, bloop’ sound of bubbling mud pools greeted me on my first visit to a geothermal prospect in Costa Rica during my PhD fieldwork in the mid 1980s. Heat energy was literally pouring out of the ground, and the visit opened my eyes to the potential of geothermal energy as a renewable energy resource. Now, some 30 years later, geothermal power produces some 15% of Costa Rica’s electricity, with 80% coming from the prospect I studied. This, together with power from other geothermal areas and a very large hydroelectric capacity, allows >99% of Costa Rica’s electricity generation to be from renewable sources, and the country aims for its power supply to be carbon neutral by 2021.

And Costa Rica is not the only country with high aims. I write the first part of this blog on the return leg of a long-haul flight from Mexico where I have attended a meeting of the GEMex project - a €20M EU-Mexico collaboration which aims to enhance understanding of two geothermal systems east of Mexico City. Over 100 scientists from across Europe and Mexico spent 4 days visiting working geothermal operations, discussing their latest data, and trying to combine many different strands of research into coherent models for the two study sites.

Our busy schedule started with a four-hour ride in the back of a minibus to the Los Azufres geothermal field. This geothermal field has an installed capacity of about 200 MW, and produces some 20% of Mexico’s geothermal power. The geothermal field covers many square kms, and is in a beautiful area of rolling countryside. We walked through pine tree-lined valleys to study natural features of hydrothermal areas, including fumaroles, bubbling pools and hydrothermally-altered rocks. We were also allowed to visit the surface infrastructure of a geothermal plant, including: production wells, injection wells, turbine halls and the control centre of the whole operation. Unfortunately, time did not allow us to visit the numerous geothermal spas in the area.

From L-R: GEMex project participants inspect the wellhead of a producing geothermal borehole; A similar image but this
 time taken with an infra-red camera, with white and yellow areas showing the hot steel of the wellhead (and the relatively
 cold people being barely visible left of centre). The steel of the wellhead had a temperature of approximately 150°C.
 
The following three days were spent in Morelia discussing progress on our investigations of the two study sites: at Los Humeros, a currently working geothermal field where its operators want to deepen boreholes, but where little is known about the hotter fluids below the currently exploited zone; and at Acoculco, a prospective, but poorly understood geothermal area where fluid flow rates have been unexpectedly low. BGS input to the programme includes:
  • Study of exhumed, ancient systems that may be analogous to what may lie below the currently active geothermal systems, and where we can investigate fluid-rock reaction processes in detail;
  • UAV-based thermal imaging of warm/hot vents at Los Humeros to identify features conducting warm fluids and to try to match their position with geological structures (i.e. faults);
  • Surface gas monitoring to also identify conductive features;
  • And lab experimental and mineralogical studies to fluid-rock reaction processes that may impact fluid flow with the deep, currently exploited geothermal reservoir.
Developing Los Humeros and Acoculco, and other systems, will help Mexico achieve its own target of 50% of its energy from ‘clean energy sources’ by 2050. The knowledge learned will also help in Europe’s geothermal development, which could provide an important contribution towards the European target of at least 20% of its total energy needs being via renewable sources by 2020, and 32% by 2030.

Whilst achieving 100% renewable energy generation is akin to the Holy Grail of national energy targets, any significant move in that direction would mark a huge shift away from our dependence on CO2-producing fossil fuels which have been the mainstay of our energy-generating technologies since the Industrial Revolution. However, we must make this transition, as climate change driven by release of greenhouse gasses to the atmosphere is one of the biggest challenges we currently face.

The drilling rig under construction at
United Downs in Cornwall.

Part Two - The UK
 

And the UK is also rising to the challenge of renewable energy generation. On returning to the UK I travelled to Cornwall where a large drilling rig is being erected at United Downs. Once assembled, it will spend some 7 months drilling two deep boreholes into the Carnmenellis Granite, one of which could be up to 4.5km deep (thereby becoming the deepest onshore borehole in the UK). This £18M United Downs Deep Geothermal Power Project aims to tap deep natural fractures filled with groundwater at 180-190°C and prove the feasibility of a fully working ‘engineered geothermal system’ (EGS) that can export electrical power to the national grid. This exciting project will utilise modern technologies to convert heat energy to electricity, and builds on expertise gained in the previous ‘Hot Dry Rock’ geothermal project which ran in Cornwall in the 1980s-1990s. If the United Downs Deep Geothermal Power Project succeeds, then it will open up the possibility of parts of the UK’s deep geosphere becoming a renewable energy resource for the future.

Since starting work on this blog, I found out that I have just won £1.8M from NERC for a Highlight Topic focussed on understanding the deep geothermal resources of Cornwall (project = GWatt). This study (which also involves Herriot Watt University, Camborne School of Mines, GeoScience, Geothermal Engineering Ltd, and the Cornwall and Isles Of Scilly Local Enterprise Partnership) aims to reduce the uncertainty associated with geothermal exploration through a detailed appraisal of existing and newly gathered data. Key to this will be the incorporation of new data coming from the United Downs Deep Geothermal Power project.

Geochemistry and Health in the Kenyan Rift Valley...by Michael Watts, Diana Menya and Odipo Osano

The Inorganic Geochemistry team within the Centre for Environmental Geochemistry (CEG) has, with partners from Moi University and the University of Eldoret (UoE) recently completed another round of environmental and human biomonitoring sampling in West Kenya, ranging from the tea estates in Nandi Hills and Kericho, as well as the sugar cane belt across Kisumu County. This study started by joining research led by Dr Diana Menya at Moi University (CNN article) and Dr Valerie McCormack from the International Agency for Research on Cancer (IARC) are studying the high incidence of esophageal squamous cell cancer (ESCC) in the western part of Kenya including the Great Rift valley region. It is the 8th most common cancer by incidence worldwide and in Kenya it is the most common cancer in men and third most common in women. Initially the environmental survey was targeted at complementing a case-control study being conducted by Moi-IARC in several counties around Eldoret to provide a measure of environmental and dietary factors (see previous blog), alongside various causal factors that are now under investigation – consumption of a high ethanol traditional alcoholic brew, chang’aa  or ‘kill me quick', cigarette smoking and hot tea drinking, but they are unlikely to fully explain the burden.

Essentially, this project sets out to demonstrate the value of cross-disciplinary collaboration between epidemiologists, health practitioners, biostatisticians, geochemists, farmers and local agricultural extension workers. A great deal of interest was created amongst the communities who welcomed the research and could provide useful local knowledge with respect to farming and local health issues.

Tea estates in Nandi Hills and 800m drop down from Nandi into Kisumu County - sugar belt.
Over the past two years, with support from the BGS-ODA programme and CEG, the targets have widened to the collection of urine samples to provide a simple measure of population health status for micronutrients-MN’s essential to health (e.g. iodine, selenium) and potentially harmful elements-PHE’s (e.g. arsenic, chromium). Additional information is collected alongside drinking water, such as usage, reliability and source data that will supplement drinking water supply data from teams working across Africa led by Prof. Alan MacDonald – integration of datasets.  Training has also been a key theme of the overall project, both for environmental/laboratory scientists from UoE and Public Health Officers (PHO) from each County Ministry of Health, to improve local capacity and build long-term partnerships to exploit funding opportunities. Overall, the quality assurance processes are repeatedly reinforced, from the point of planning sample collection, through collection of data and samples in the field, their preservation and maintaining the integrity of the sample until return to the laboratory at UoE or BGS for analyses. Ensuring a traceable audit trail from collection to reporting of data to enable reliable interpretation of data and reporting of data to local Ministry of Agriculture extension services and communication via PHO’s and joint publication in peer reviewed literature.  Ultimately the training approach and transfer of surplus laboratory equipment from BGS and UK research partners will help in the teaching activities at UoE to develop local laboratory capability and systems to provide confidence in data output.  Training in field activities has allowed us to scale up field collections cost effectively, but importantly forge strong partnerships.


So what are we collecting?


At each site we capture data on field sheets a range of data relating to the land-use, crops grown, drinking water source/usage and any local health problems (e.g. ESCC, goitre), along with soil, a panel of crops grown and eaten from the garden or farm, drinking water and a urine sample. The latter often results in some giggling, but nearly always enthusiastic participation, despite the potential embarrassment.  We had three vehicles out in the field on predetermined routes to coordinate daily collections, often at difficult to reach places, but thankfully the weather held and many roads although difficult were passable. Of course, the entry point led by the PHO’s and often the drivers (they have a wider range of language skills) is invaluable in explaining what we are doing and why, in order to gain permission from participants at each site and can often result in a deluge of local information. In fact, we have rarely experienced a negative response, rather a great deal of interest and help.  The challenge will be how we report data back in an appropriate format.  

Sampling in hard to reach places in Nandi hills where rapid changes from forest to farming taking place.

Wider uses for data


The collection points rather than being led by the location of ESCC case-control sites has taken on a spatial link across each county, simply driven by spatial coverage where safe access is possible or where populations reside in the rural community (e.g. cannot access sugar cane estates, rainforest).  In addition, we have incorporated into planning collection sites published soil chemistry parameters. Overall, data will be useful to agricultural extension officers to provide advice to farmers on soil management, to PHO’s in gaining datasets to estimate health status from a sample population within each county (e.g. micronutrient deficiencies, exposure to PHE’s). In the coming years, IARC-Moi University will use the environmental data/dietary intakes to support spot sampling for ESCC-control collection points, utilising the trained field personnel.

Data is already showing potential links through to developing other projects with UoE-Moi University, along the lines of pollution pathways, soil erosion (recent Global Challenge Research Fund (GCRF) bid), links through to Lake Victoria pollution and impact on fisheries/aquaculture. In fact, Andy Marriott stayed on in Kenya for another week to continue his Newton funded grant partnered with UoE, Kenya Marine and Fisheries Institute (KMFRI) and Ministry of Agriculture/Fisheries to sample fish, sediments and water whilst based on the KMFRI boat – blog to follow. Training in both directions has progressed, in that Olivier Humphrey (CEG/BGS University Funding Initiative (BUFI) PhD) joined the team for land-based sampling for a second time and very competently led one of the three field vehicles, collated all of the database information and provided training in the labs to UoE staff and a mix of 6 under-/postgraduate students – blog to follow.  Tom Kelly also joined Andy on the KMFRI field boat for his first BGS overseas trip.

Laboratory training at University of Eldoret.
Efforts to develop project partnerships and two-way exchanges of staff and students has been recognised in that suggestions for an MOU have been discussed with the VC and DVC for Research and extension services at UoE. The coming months will see how we consolidate on the partnership and friendships built so far. I say friendships, because whilst we all recognise the value of what we are doing, the long days in the field on bumpy and dusty roads, plans not always surviving intact, the shared experience of tiredness and sometimes frustration is always backed up by lots of laughter - which is what you remember when leaving Africa.

Last leg of ORCHESTRA cruise part 5…by Melanie Leng

Mel on board the RRS James Clark Ross
Melanie Leng is currently taking part in an expedition to the Southern Ocean as part of  ORCHESTRA (Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports), a NERC funded programme with partners at the British Antarctic Survey (lead), the National Oceanography Centre, Plymouth Marine Laboratory, and many more including BGS. Here she updates us as she nears the end of her expedition on the RRS James Clark Ross…

We have been at sea for around 3 weeks on the RRS James Clark Ross crossing the Drake Passage from the Burwood Bank (an undersea shallow ridge off eastern South America) to Elephant Island (off the tip of the Antarctic Peninsula). All the work has been successfully completed. Personally I have collected over 600 water samples (with help from my overnight buddy, Julia Rulent from the Universities of Bangor and Liverpool) for oxygen and carbon isotope analysis, and around 250 for radiocarbon analysis. These samples are just one leg of the 5 year ORCHESTRA research programme to try to understand the structure of the Southern Ocean and more importantly what changes are taking place within the ocean because of human impact. These samples were taken from over 40 casts of the CTD (see blog part 4) from as deep at 5km in the ocean. On board others from NERC research institutes and UK universities are measuring salinity, temperature, nutrients, carbon, plastics, silicon and nitrogen isotopes, CFCs, and SF6. Many measurements have been made on board with instruments that the scientists have brought a long, the instruments strapped to benches in the ship’s laboratories, to stop them falling off as the ship rocks and rolls. In the 3 weeks on board I can’t remember a calm period, several hurricanes have passed over us bringing massive ocean swells and waves.

There has been a lot of work done, round the clock sampling in periods of relative stability, to make up for time lost due to the weather. The highs include 2 humpbacked whales (mother and calf) visiting us, the mother was enormous, perhaps 12-14m in length. The whales had a distinctive body shape, with long pectoral fins and a knobbly head, they repeatedly lifted their heads out of the water to take a look at the orange high visibility clothing clad scientists on deck, and did several back flips and tail whips. The whales were making their way south in the Southern Ocean to feed off krill and small fish, before returning to tropical waters to breed and give birth, where they live off their fat reserves built up in the south. In the past these amazing creatures have been a target for the whaling industry, and have been on the brink of extinction before protocols were put in place to limit whale fishing. The humpback whale population is increasing but still fishing gear, collisions with ships and noise pollution continue to impact the species.

One day we were also escorted for several hours by a pod of 30 or so pilot whales. It was a mixed group with several large animals of 6-8m, and many calves. The pilot whales frolicked in the waves, enjoying the speed that the currents afforded them, occasionally they stopped and peered at us, lifting their bulbous heads out of the water. With the pod were small clusters of penguins, visible as they surfed the waves on their hunt for small fish. Albatross and petrels follow the ship all the time, possibly for refuse or the small marine animals that are brought to the surface by the motion of the ship, or perhaps they are taking advantage of air currents produced by the ship...

In a few hours we will be docked at Stanley on the Falkland Islands, where we will spend a couple of days demobilizing the ship, taking inventories of samples, packing up the equipment, and generally clearing up for the next cruise. The RSS James Clark Ross will be leaving Stanley in early December with a new group of scientists working on a project called ICEBERGS, they will be travelling along the west side of the Antarctic Peninsula, to see how rapidly retreating glaciers are changing the environment there. They will also be collecting gravity cores to put recent ice shelf retreat into historical (Holocene) context. You can follow them on: Instagram: developingoceans and twitter @ICEBERGS_JCR.

Overall its been a successful research cruise, in no small way down to Dr Yvonne Firing for her leadership and management. Also thanks to the dedicated crew on board, engineers, deck crew and stewards who all played their part.

Using workshops to spark ideas: collaborative working in the Lyell Centre…by Amelia Baptie

Workshop attendees getting to know each other.
On 24th October staff and students were invited to a joint workshop between BGS, the Lyell Centre and the Heriot Watt University School of Mathematical and Computer Sciences (MACS). The aim of the workshop was for BGS and Lyell Centre informatics staff and developers to meet each other, and MACS students and staff, with a view to thinking about areas where we can work in collaboration.

Flash talks to spark ideas


The day was broken down in to two parts during which the 25 attendees could present flash talks on their area of expertise and ongoing work. The morning was dedicated to Maths, Modelling and Statistics and the afternoon focused on Computer Science and Informatics. Each of the flash talks was designed to prompt and spark ideas for potential future collaborations between our staff and organisations.

The BGS team presented talks on geomagnetic field modelling and the ongoing role and work of the Informatics department including data delivery, data science, geosemantics, European and International collaborations, commercial and overseas development work. 


Learning about each other


It was fascinating to hear about the work of our neighbouring colleagues. Having the opportunity to hear about (for example) differential equations, robotic bar tenders, mathematical modelling for disease in plants, humans and animals, identifying tourist landmarks using spatial and semantic clustering and the integration of heterogeneous data for crisis management is not something that we have the opportunity to do very often!

Overlapping research


A lively lunch and coffee session enabled everyone to get together to get to know each other and to note down areas of overlapping research and work interest. We had a large collection of ideas on post it notes by the end of the day. 

Ideas for the future


Ideas for potential collaborations include building augmented reality apps, time series data analysis, human computer interaction for mobile and the use of data for crisis management. These are just a few of the 30+ ideas that came out of the workshop.

We would like to say a big thank you to the Heriot Watt Mathematical and Computer Sciences staff for hosting this event and we look forward to getting again together in the future for events such as a proposed hackathon.

As for the collaborations that come out of this workshop, please watch this space!

Learning about cascading hazards at the iRALL School in China...by Jim Whiteley

Earlier this year, I wrote about my experiences of attending an interdisciplinary workshop in Mexico, and how these approaches foster a rounded approach to addressing the challenges in communicating risk in earth sciences research. In the field of geohazards, this approach is increasingly becoming adopted due to the concept of “cascading hazards”, or in other words, recognising that when a natural hazard causes a human disaster it often does so as part of a chain of events, rather than as a standalone incident. This is especially true in my field of research; landslides. Landslides are, after all, geological phenomena studied by a wide range of “geoscientists” (read: geologists, geomorphologists, remote sensors, geophysicists, meteorologists, environmental scientists, risk assessors, geotechnical and civil engineers, disaster risk-reduction agencies, the list goes on). Sadly, these natural hazards affect many people across the globe, and we have had several shocking reminders in recent months of how landslides are an inextricable hazard in areas prone to earthquakes and extremes of precipitation.

The iRALL, or the ‘International Research Association on Large Landslides’, is a consortium of researchers from across the world trying to adopt this approach to understanding cascading hazards, with a particular focus on landslides. I was lucky enough to attend the ‘iRALL School 2018: Field data collection, monitoring and modelling of large landslides’ in October this year, hosted by the State Key Laboratory of Geohazard Prevention and Geoenvironment Protection (SKLGP) at Chengdu University of Technology (CDUT), Chengdu, China. The school was attended by over 30 postgraduate and postdoctoral researchers working in fields related to landslide and earthquake research. The diversity of students, both in terms of subjects and origins, was staggering: geotechnical and civil engineers from the UK, landslide specialists from China, soil scientists from Japan, geologists from the Himalaya region, remote sensing researchers from Italy, earthquake engineers from South America, geophysicists from Belgium; and that’s just some of the students! In the two weeks we spent in China, we received presentations from a plethora of global experts, delivering lectures in all aspects of landslide studies, including landslide failure mechanisms, hydrology, geophysics, modelling, earthquake responses, remote sensing, and runout analysis amongst others. Having such a well-structured program of distilled knowledge delivered by these world-class researchers would have been enough, but one of the highlights of the school was the fieldwork attached to the lectures.


The scale of landslides affecting Beichuan County is difficult to grasp: in this
photo of the Tangjiwan landslide, the red arrow points to a one story building.
 This landslide was triggered by the 2008 Wenchuan earthquake,
and reactivated by heavy rainfall in 2016.
The first four days of the school were spent at SKLGP at CDUT, learning about the cascading hazard chain caused by the 2008 Wenchuan earthquake, another poignant event which demonstrates the interconnectivity of natural hazards. On 12th May 2008, a magnitude 7.9 earthquake occurred in Beichuan County, China’s largest seismic event for over 50 years. The earthquake triggered the immediate destabilisation of more than 60,000 landslides, and affected an area of over 35,000 km2; the largest of these, the Daguangbao landslide, had an estimated volume of 1.2 billion m3 (Huang and Fan, 2013). It is difficult to comprehend numbers on these scales, but here’s an attempt: 35,000 km2 is an area bigger than the Netherlands, and 1.2 billion m3 is the amount of material you would need to fill the O2 Arena in London 430 times over. These comparisons still don’t manage to convey the scale of the devastation of the 2008 Wenchuan earthquake, and so after the first four days in Chengdu, it was time to move three hours north to Beichuan County, to see first-hand the impacts of the earthquake from a decade ago. We would spend the next ten days here, continuing a series of excellent lectures punctuated with visits to the field to see and study the landscape features that we were learning about in the classroom.

The most sobering memorial of the 2008 Wenchuan earthquake is the ‘Beichuan Earthquake Historic Site’, comprising the stabilised remains of collapsed and partially-collapsed buildings of the town of Old Beichuan. This town was situated close to the epicentre of the Wenchuan earthquake, and consequently suffered huge damage during the shaking, as well as being impacted by two large landslides which buried buildings in the town; one of these landslides buried a school with over 600 students and teachers inside. Today, a single basketball hoop in the corner of a buried playground is all that identifies it as once being a school. In total, around 20,000 people died in a town with a population of 30,000. Earth science is an applied field of study, and as such, researchers are often more aware of the impact of their research on the public than in some other areas of science. Despite this, we don’t always come this close to the devastation that justifies the importance of our research in the first place.

River erosion damaging check-dams designed to stop debris flows is still a problem in Beichuan County, a decade after the
 2008 Wenchuan earthquake.
It may be a cliché, but seeing is believing, and the iRALL School provided many opportunities to see the lasting impacts of large slope failures, both to society and the landscape. The risk of debris flows resulting from the blocking of rivers by landslides (a further step in the cascading hazard chain surrounding earthquakes and landslides) continues to be a hazard threatening people in Beichuan County today. Debris flow check-dams installed after the 2008 Wenchuan earthquake are still being constantly maintained or replaced to provide protection to vulnerable river valleys, and the risk of reactivation of landslides in a seismically active area is always present. But this is why organisations such as the iRALL, and their activities such as the iRALL School are so important; it is near impossible to gain a true understanding of the impact of cascading hazards without bringing the classroom and the field together. The same is true when trying to work on solutions to lessen the impact of these cascading hazard chains. It is only by collaborating with people from a broad range of backgrounds, skills and experiences can we expect to come up with effective solutions that are more than the sum of their parts.

Jim Whiteley is a PhD student funded through the BGS University Funding Initiative (BUFI). The aim of BUFI is to encourage and fund science at the PhD level. At present there are around 130 PhD students who are based at about 35 UK universities and research institutes. BUFI do not fund applications from individuals.

Sampling starts on the RRS James Clark Ross: ORCHESTRA part 4…by Melanie Leng



Melanie Leng is currently part taking in an expedition to the Southern Ocean as part of  ORCHESTRA (Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports), a NERC funded programme with partners at the British Antarctic Survey (lead), the National Oceanography Centre, Plymouth Marine Laboratory, and many more including BGS and several UK universities. This is the fourth blog about her trip where the work begins on the RRS James Clark Ross…

Cruising track from the south from the
Burwood Bank (an undersea shallow ridge
off eastern South America) to Elephant
Island (off the tip of the Antarctic Peninsula).
We are currently cruising south from the Falkland Islands, crossing the Drake Passage from the Burwood Bank (an undersea shallow ridge off eastern South America) to Elephant Island (off the tip of the Antarctic Peninsula). We are repeating some established measurements of ocean temperature, salinity, oxygen, and currents that have been made with support from NERC funding since the early 1990’s but we are also adding some new novel measurements, including O, C, N and Si isotopes, nutrients, and micro plastics to help us understand the changes in the ocean. Most of the measurements are made on discrete water samples collected from depth profiles (down to the sea bed which in places is 5km below the sea surface) taken at regular distances along the transect. The water samples are taken using an instrument called a CTD. A CTD is an instrument used to measure the Conductivity (used to determine salinity), Temperature, and pressure of seawater (the D stands for "depth," which is closely related to pressure) of the ocean but also to collect discrete water samples.  The water samples are taken using a rosette or carousel of “Niskin” bottles. Niskin bottles can be opened at both ends. The open bottle is lowered into the ocean on a wire until it reaches a certain depth and then the bottle is closed by a weighted trigger that is sent down the cable from the surface. Our Niskin bottles are set up in a circular rosette of 24 bottles attached around the CTD instrument. This allows us to take samples at different water depths in a way that seals off the sample and allows it to be brought to the surface without mixing with water from different depths. Getting water samples from different depths in the ocean is important to understand how the water chemistry and physical properties changes with depth.

The CDT (all-women!) sampling team
While the scientist work we have a dedicated crew on board that support us, for the sampling we are indebted to the engineers and deck crew for help with the CTD, as well as those responsible for the successful operation of the ship.

On board the RRS James Clark Ross: ORCHESTRA part 3…by Melanie Leng

Melanie Leng is currently part taking in an expedition to the Southern Ocean as part of ORCHESTRA (Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports), a NERC funded programme with partners at the British Antarctic Survey (lead), the National Oceanography Centre, Plymouth Marine Laboratory, and many more including BGS. This is the third blog about her trip where she updates us on her arrival on the RRS James Clark Ross…

We arrived on the RRS James Clark Ross a couple of days ago to begin the mobilisation (ie organizing our equipment that we will be using to make measurements and take samples) before we set sail. The equipment has been organised over the summer by numerous science teams (to name a few: BAS, NOC, BGS, University of Exeter, University of Southampton) and loaded onto the ship while it was docked in Harwich. Hundreds of boxes from numerous science teams were stowed in the hold. We had to bring all the equipment up to the dedicated laboratories that we will need for sampling across the Drake Passage. Much equipment remains in the hold for subsequent cruises, following this one, before the ship heads back to the UK. The equipment in the labs has been securely strapped down as we are anticipating rough seas. For my isotope analysis, I will take bottles of ocean water for analysis back in the BGS laboratories. Others make measurements on the ship, as the analysis are either relatively easy or the samples will not preserve till we can get them back to our laboratories in the UK.

We are currently cruising south from the Falkland Islands and will be crossing the Drake Passage to the Antarctic Peninsula in a few days, repeating some measurements of ocean temperature, salinity, oxygen, and currents that have been made with support from NERC funding since the early 1990’s. We will also be adding new novel measurements, including O, C, N and Si isotopes and micro plastics to the arsenal of information we will be gathering to help us understand the changes in the ocean.

The samples I am collecting are for oxygen and carbon isotopes. The oxygen isotope data will tell us about how much freshwater to seawater there is at particular locations (which will help us understand melting of the Antarctic ice mass and therefore heat) and the carbon isotopes will tell us where the carbon is from and how the ocean uses the carbon. These measurements are particularly important to understand because of the significant changes the Earth is experiencing during the Anthropocene period we are living in.

While the scientist work we have a dedicated crew on board that support us, these are engineers, deck crew and stewards to name a few. The crew, often overlooked, have significant responsibilities which are integral to the successful operation of the ship and our research.

So far the weather has been good to us, blue skies and calm seas, hopefully it will continue!
