Project outline

The Last Glacial Maximum (LGM) ~26-19 thousand years ago was the most recent glacial period on Earth, typified by extensive northern hemisphere glaciation, average global temperatures around 4 °C cooler than today and global sea levels 130 m lower than the present. As climate warmed towards the present day and the vast northern ice sheets shrank, large volumes of meltwater flooded to the coasts, raising sea level and disrupting global-scale ocean circulation, and rapid changes in surface topography reorganized patterns of atmospheric circulation. Known as the last deglaciation, this period was an exciting time of abrupt changes in surface climate (including warming and cooling events) and within the worlds oceans.

The most recent assessment report from the Intergovernmental Panel on Climate Change (IPPC AR5) has stated that a number of issues remain regarding our understanding of the Last Glacial Maximum; namely the mismatch between proxy data and models regarding temperature estimates, the uncertainty surrounding the magnitude of tropical sea surface cooling, and the role of seasonal productivity and response of proxy-hosting plankton to variations in water column temperature and vertical stratification.

This project will focus upon direct sampling and analysis of cores donated by BG Group that have been collected from the Uruguayan Margin with a number of geochemical and micropalaeontological investigations upon material spanning the Last Glacial Maximum and subsequent deglaciation.
