Dr Jack Lacey from the BGS Stable Isotope Facility attended EGU from April 7 - 12. Today he tells us about his week and the research he
presented…
The European Geosciences Union
(EGU) General Assembly is one of the foremost events in the geoscience calendar
and is held around this time annually in Vienna, Austria. At the conference
this year there were more than 16,000 scientific talks and posters as part of
over 680 unique sessions covering an extensive range of geoscience themes – all
within 5 days.
The research I presented at EGU
aims to help us better understand environmental change and anthropogenic impact
in Peninsular Malaysia, with a particular focus on past changes in monsoonal
rainfall as there many flood-prone areas across the country. Given the human
and economic costs of flooding, rainfall variability needs to be constrained
beyond the instrumental record, which only covers the last several decades.
There are very few records, such as from lakes and speleothem, in Southeast
Asia that can be used to investigate past changes in monsoonal rainfall and no
well-dated, land-based records from Peninsular Malaysia.

Overall there were 29 staff
from the British Geological Survey presenting their latest research and
co-ordinating sessions at EGU, including science areas such as groundwater,
earth hazards, marine geoscience, geochronology. To see a complete list of the
BGS staff who attended EGU and the work they presented check out this previous
blog post.

This study uses monitoring data
and sediment cores from Tasik Chini, a lake located in the state of Pahang in
Peninsula Malaysia, which is one of the few lake basins in this region. The
cores contain sediment that was deposited over the last 5000 years, and we have
used multiple geochemical techniques to identify large changes in organic
matter production and preservation, hydrology, and water quality over the
lake’s history. The most pronounced variations occur during the past 150 years,
especially since the 1950s. Together, this new information demonstrates major
shifts in the Tasik Chini ecosystem and suggests that changes were most likely
driven by a dynamic monsoon system during earlier part of the record (Middle to
Late Holocene) and more recently by human activity in the catchment.
