I have recently moved to the University of Nottingham to begin phase II of my PhD research. This is going to involve learning lots of geochemistry techniques in order to improve methods for understanding past environments and climate.

My project on the Meres involves collecting the sediments that are accumulating in the lake and trying to better understand what environmental information we can extract from the organic geochemistry.I want to be able to assess the different sources of organic matter, whether from aquatic productivity (due to past pollution for example from human sewage that has entered the lakes in the past) or from increased erosion of the soils that surround the lakes due to changes in farming or land management. The sediments have been accumulating for 12000 years, but for now I am focussing on the last few hundred years to see if human impact is recorded in the sediments especially since the Industrial Revolution c. 250 years ago.
Understanding past pollution and how lakes respond is important for conservation and protecting our environment.By Jack Lacey, @JackHLacey
