Ocean colour is the water-leaving radiance in the visible and near-infrared just above the ocean surface owing to selective absorption and scattering by phytoplankton and its pigments such as chlorophyll, as well as dissolved organic matter and suspended particulate matter in the subsurface ocean waters. Ocean colour carries useful information concerning biogeochemical properties of the water b...

Trace metals (Fe, Mn, Cu, Co, Ni. Pb, Cd and Cr) analyses in particulate matter and sediments were carried out at 16 different stations in the Godavari mangrove ecosystem covering the three regions viz., Kakinada (KKD) bay, Goutami-Godavari estuary (GGE) and Coringa and Gaderu mangrove environments (CGME). Higher concentrations of trace metals in particulate matter and in sediments were noticed...

We present the first measurements of nitrogen isotopic composition (δ15N) in suspended particulate matter (SPM) of the surface Bay of Bengal (BOB) at 24 different locations during pre(April–May 2003) and post(September– October 2002) monsoon seasons. The δ15N values of particulate organic nitrogen (PON) in surface suspended matter of coastal and northern open BOB show mixing between continental...

--Sedimentation of particulate carbon and nitrogen, pigments (fluorometric and HPLC analysis) as well as the activity of the respiratory electron transport system in sedimented matter were studied with unpoisoned, short-term deployed sediment traps during June in the central Barents Sea. The vertical flux of sedimenting material and its biochemical composition in the central Barents Sea was dif...
