      Upper water column dynamics in the eastern Arabian Sea were reconstructed in order to investigate changes in the activity of the South Asian / Indian monsoon during the early Pleistocene (c. monsoon precipitation induced runoff from the Western Ghats and reduced light penetration driven by cloud cover. The variation in heterotrophic Protoperidinium species abundance could be related to variation in the Oxygen Minimum Zone (OMZ) intensity, with better preservation during intense OMZ in MIS 3 and the late Holocene (~3 ka onwards).

      Some of the glacial intervals (i.e., MIS 6 and 8) are also characterized by pteropod spikes reflecting deepening of aragonite compensation depth (ACD) and relatively less intense oxygen minimum zone (OMZ) in this region due to deep sea mixing and thermocline ventilation, and relatively less intense surface productivity during winter monsoon. A yr record of climate change in varved sediments from the oxygen minimum zone off Pakistan, Northeastern Arabian Sea. Quaternary Resea (). 39 –

      The vast Indo-Gangetic Plain in South Asia has been home to some of the world’s oldest civilizations, whose fortunes ebbed and flowed with time—plausibly driven in part by shifts in the spatiotemporal patterns of the Indian summer monsoon rainfall. We use speleothem oxygen isotope records from North India to reconstruct the monsoon’s variability on socially relevant time scales, allowing. ennial oxygen minimum zone (OMZ) with dissolved O2 Arabian Sea at water depths between and m (refs 15 and 16). The acute oxygen deficiency leads to large scale denitrification in the water column within a zone that extends from the continental margin off Gujarat to the.
