Contrasts in calcium carbonate dissolution above the lysocline in the equatorial Indian Ocean over the last ∼40 ka

Ramanand Yadav et al.

Summary: Understanding calcite dissolution above the lysocline is crucial for the oceanic calcium carbonate cycle. Analysis of sediments from the central equatorial Indian Ocean over a 43 ka period indicates increased calcite dissolution during MIS-3 and the LGM, with further intensification during the Holocene. Preservation of calcite during the last deglacial period is likely due to increased deep-sea carbonate ion concentration related to CO2 outgassing during the LGM.

Sediment oxygen consumption: Role in the global marine carbon cycle

Bo Barker Jorgensen et al.

Summary: The seabed is crucial for the marine carbon cycle, serving as a terminal location for organic matter oxidation, a bioreactor, and a repository for reactive organic carbon. This study compiles data on marine sediment oxygen uptake to understand the constraints on organic matter mineralization rates and their relationship with environmental parameters. Results show that seabed oxygen uptake is primarily controlled by ocean depth and primary productivity. The study also discusses oxygen transport, aerobic respiration, and anaerobic processes in the seabed. A global map of seabed oxygen uptake rates was created, revealing the oxidation of 212 Tmol C yr(-1) in marine sediments. A comparison with the flux of particulate organic carbon suggests a deficit in carbon turnover in the underlying seabed.

Monsoon-related changes in surface hydrography and productivity in the Bay of Bengal over the last 45 kyr BP

Komal Verma et al.

Summary: This study reconstructs the surface hydrographic structure and productivity in the western Bay of Bengal over the past 45 kyr BP using the temporal variations of mixed-layer planktic foraminiferal abundances in a sediment core. The results show that the surface hydrographic conditions and productivity were influenced by Northern Hemisphere climatic events and changes in monsoon precipitation and wind intensity.

Sedimentary response to sea level and climate changes in the inner sea of Maldives carbonate platform over the past 30 kyr

Ling-Gang Tang et al.

Summary: By analyzing sediment samples from the Maldives inner sea, it was found that sea level and climate changes had a significant impact on the sedimentary process, mainly reflected in the changes of reef-sourced material controlled by sea level and climate changes.
