The role of the Southern Ocean in regulating atmospheric CO2 on glacial-interglacial timescales
Read more of: The role of the Southern Ocean in regulating atmospheric CO2 on glacial-interglacial timescalesThis project attempts to reconstruct changes in the intermediate-deep ocean density gradient in the South Atlantic across the last deglaciation in order to assess the link between deep ocean stratification and atmospheric CO2.

The role of Antarctic sea-ice in global climate
Read more of: The role of Antarctic sea-ice in global climateThis project examines Antarctic sea-ice’s role in global climate, using marine sediment and ice core records to reconstruct past sea-ice extent.

Impact of Southern Westerly Winds and Circumpolar Deep Water on climate and marine ecology
Read more of: Impact of Southern Westerly Winds and Circumpolar Deep Water on climate and marine ecologyResearch project investigating how shifting southern westerly winds drive warm Circumpolar Deep Water onto the West Antarctic Peninsula shelf, accelerating glacier melt, reducing sea ice, and transforming marine ecosystems.

Identification of glacial-time sources for Antarctic deep- and bottom-water masses
Read more of: Identification of glacial-time sources for Antarctic deep- and bottom-water massesBy studying the geochemistry of deep marine sediments recovered from the Southern Ocean sea floor, this research aims to establish the extent of this reorganisation of deep water circulation, and to better understand its potential impacts on past climate.

Surface exposure dating
Read more of: Surface exposure datingWhat can surface exposure dating tell us about ice sheet history? Information on the shape and size of the Antarctic Ice Sheets over the past 20,000 years is contained within […]

Rapid drilling to find ancient ice
Read more of: Rapid drilling to find ancient iceA new drill (the Rapid Access Isotope Drill, or RAID) is being developed by BAS which, rather than collect a full ice-core, this drill will chop up the ice and will allow collecting ice chippings.

Ocean-driven ice-shelf thinning in Antarctica
Read more of: Ocean-driven ice-shelf thinning in AntarcticaBy exploiting advances in ice sheet modelling, and new Antarctic-wide datasets, this project aims to predict how far and how fast the observed ocean-driven thinning of floating ice shelves will propagate into the interior of the Antarctic ice sheet, and assess the consequences for global sea level over decadal-to-centennial timescales.

Ice Sheet Modelling
Read more of: Ice Sheet ModellingThe ice sheet modelling group integrates observational data with dynamical models to improve our representation of how the ice flows beneath the surface, and to reveal how the shape and flow of the Antarctic ice sheet has changed in the past.

Antarctic Climate over the last millennia
Read more of: Antarctic Climate over the last millenniaThis project used ice cores drilled across the Antarctic Peninsula and West Antarctica to reconstruct past climate and understand whether the recent warming in these rapidly changing regions is unusual over longer timescales..

Climate and Ice during the Last Interglacial
Read more of: Climate and Ice during the Last InterglacialThis project studies the last Interglacial (129-116 thousand years ago, ka) when CO2 and global temperature were both higher than they were before human industrialisation. By examining Last Interglacial climate, we can gain insights into climate processes and feedbacks close to those expected by the end of the 21st century.

Impact of global disturbances on evolution of polar life
Read more of: Impact of global disturbances on evolution of polar lifeWhy does global biodiversity show such a steep increase just as climates were deteriorating?
