Short summary
In the Edisto Inlet, Ross Sea, over the last 3.6 kyr, a marked transition at 2.7–2.5 kyr BP occurred. Geochemical proxies and changes in the foraminiferal community suggest a change from multi-year to seasonal sea ice, likely linked to mCDW (modified Circumpolar Deep Water) intrusion. The study integrates ecological information and geochemical data to unveil connections between mCDW, sea-ice conditions and the SAM (Southern Annular Mode) in Edisto, highlighting it as a key site for regional paleoclimate reconstruction over the Ross Sea.
