Southern Ocean marine sediment core sea-ice records for the last 150 000 years Matthew Chadwick, Xavier Crosta, Oliver Esper, and Karen E. Kohfeld

Short summary
Algae preserved in seafloor sediments have allowed us to reconstruct how Antarctic sea ice has varied between cold and warm time periods in the last 130 000 years. The patterns and timings of sea-ice increase and decrease vary between different parts of the Southern Ocean. Sea ice is most sensitive to changing climate at the external edges of Southern Ocean gyres (large areas of rotating ocean currents).
