We analyzed calcium carbonate (CaCO%), sedimentary organic carbon (C-org %) and shell weights of selected planktic foraminifera species (Globigerinoides ruber, Pulleniatina obliquiloculata and Neogloboquadrina dutertrei) to see the contrast in carbonate preservation during the late last glacial-Holocene. Our dataset reveals that carbonate preservation declined during the last glacial maximum (LGM) and the Holocene, probably due to organic matter degradation in sediments. The ratio of C-org/CaCO was relatively higher during the LGM than during the last deglacial period (LDP) and the Holocene. Furthermore, the heavier planktic foraminifera shell weights during the LDP indicate relatively increased carbonate preservation, which is linked to the deglacial release of carbon dioxide (CO₂) from the ocean to the atmosphere.73.28334.9333Lakshadweep SeaDepartment of Science and Technologyhttps://doi.org/10.13039/501100001409MLP 2014Long-term evolution of monsoon and associated processes (LEMAP)
