RU4: Impact of past changes in ice

Over millions of years, the earth’s ice sheets have repeatedly expanded and retreated. To predict what the future holds, we first need to understand how past ice sheet changes affected the global carbon cycle and marine ecosystems.

We are drilling into onshore and offshore marine sediments in Svalbard, Greenland and Antarctica and studying how past changes in ice sheets affected ocean circulation and marine life. We are combining those insights with new understanding of ice sheet behaviour gained through seismic surveys, sub-ice geophysical surveys, ice cores and sedimentary records. This enables us to reconstruct the past impact of retreating ice on life in the oceans and greenhouse gas levels in the atmosphere. 

Our aim is to reliably estimate how carbon cycles and ocean ecosystems altered during past ice sheet retreat, so that we can improve our modelling of how the future may unfold.
