Fluctuations in productivity and denitrification in the southeastern Arabian Sea during the Late Quaternary [1]

Additional image:: 

Sedimentological and stable isotopic characteristics of sediments have been studied in a core from the south-eastern Arabian Sea containing records of the past 70 ka. Palaeoproductivity proxies such as organic carbon (Corg), total nitrogen (TN) and calcium carbonate (CaCO3) contents, show high values at the core top and during the Last Glacial Maximum (LGM) and
marine isotope stage (MIS) 4, suggesting high productivity, whereas low Corg and CaCO3 contents are associated with the MIS 1/2 and mid-MIS 3, indicating reduced productivity.
