[PDF][PDF] Implications of organic carbon, trace elemental and CaCO3 variations in a sediment core from the Arabian Sea

SS Shetye, M Sudhakar, R Mohan, A Tyagi - 2009 - nopr.niscpr.res.in
Arabian Sea differs from other oceanic areas by strong seasonal variations in sea surface
circulation controlled by the monsoonal wind system, very high primary productivity (PP) and
the presence of an intense Oxygen Minimum Zone (OMZ). Sediment core, collected from a
depth of 803 M in OMZ of eastern Arabian Sea, was analyzed for organic carbon, CaCO 3,
grain size and trace metals (Cu, Zn, Cr, Mn and Fe). Organic carbon and CaCO 3 varied
from 0.5-4.7% and 34-55.9% respectively and exhibit an inverse relation, whereas a positive …
