ORGANIC MATTER VARIATIONS IN THE NORTHWESTERN ARABIAN SEA SEDIMENTS: Athar Ali Khan, C.H. Weijden and Reichart Gert Jan

In this study composition of organic matter and its variations in marine sediments of northwestern Arabian sea has been discussed. This paper presents the geochemical analysis of organic carbon content, C/N and d13 stable carbon isotope. The primary objective was to investigate the organic matter in sediments below an upwelling area. Undisturbed sediments (Piston core NIOP-486) of late Pleistocene time was collected during Netherlands Indian Ocean Program (NIOP-1992-93). The core NIOP486 was raised from a depth of 2077 meters near the Owen ridge. This core records deposition history of last 20... Mehr ...
