We have utilized the ratio of mixed layer eutrophic to mixed layer oligotrophic foraminifer species, thermocline foraminifera species, and sedimentary organic carbon (C-org) content from the core SSD-044/GC01 to infer the Mixed layer and Thermocline variability during late glacial to Holocene. The mixed layer increases, and the thermocline deepens during Last Glacial Maximum (LGM) and vice versa during the last deglacial and Holocene which is influenced by the coupling of northeast (NE)/southwest (SW) Monsoon.
