Distribution of trace elements and total organic carbon in surface sediments of the Sulu and Sulawesi Seas (Taburan Unsur Surih dan Organik Karbon di permukaan sedimen di Laut Sulu dan Sulawesi)

The concentrations of TOC, Al, Fe, Mn, Pb, Cu, Ni, Co and Cr in 27 surface sediments have been determined from the Sulu and Sulawesi Sesa during the ‘Saintifik Perdana 2009’ expedition cruise from 18 June to 1 August 2009. Sampling was conducted to elucidate concentrations and spatial distributions...
