The current study focused to evaluate one of the important trace metal concentrations in mixed zooplankton from the waters of Bay of Bengal and Andaman Sea. The average concentration of copper from northern Bay of Bengal, central Bay of Bengal, southern Bay of Bengal, and eastern Bay of Bengal on dry weight basis was reported as 65.36 g.g -1 , 58.54 g.g -1 , 48.86 g.g -1 , 43.50 g.g -1 resp...

the surface sediment samples were analyzed for grain size carbonates (caco3) and organic carbon (oc) to obtain a preliminary view of its environmental conditions near point calimere along the southeast coast of vedaranyam, india. the total concentrations of major elements namely, si, al, fe, ca, mg, na, k and p in the surface sediments of vedaranyam coast are estimated. the element/al ratios al...

the coast of bangladesh has a specialty in terms of high bending and many off- shore islands. incorporation of the coastline and island boundaries properly in the numerical scheme is essential for accurate estimation of water levels due to surge. for that purpose a numerical scheme consisting of very fine mesh is required along the coastal belt, whereas this is unnecessary away from the coast. in...

The recent first-field phase of Indian Ocean Experiment has provided various types of aerosol data over the Arabian Sea, the Bay of Bengal and the Indian Ocean. Using optical sensors on-board numerous satellites, global aerosol parameters have been estimated by many workers. In this communication, we have used IRS P4 OCM data to retrieve the aerosol parameters over the Arabian Sea and the Bay o...

The Global International Waters Assessment (GIWA) subregion 53, Bay of Bengal (Fig. 1) includes the Bay of Bengal Large Marine Ecosystem (BOBLME) (1), and associated watersheds. The nations of Bangladesh, Bhutan, Maldives, Myanmar, Nepal and Sri Lanka are all in the Bay of Bengal Subregion (BOBSR). The major land area of India, a relatively minor part of Indonesia (eastern Sumatra), western Pen...

The study describes the range extension of the sea horse Hippocampus fuscus from the south to north east coastal waters of the India, Bay of Bengal. After 99 years since initial discovery, the Hippocampus fuscus was reported within the southern sector of the Chilika Lake. The extension range may be due to the East India Coastal Current of the Bay of Bengal and the predominance of extensive sea ...

Water masses of different temperature and salinity partially govern the distributions of chlorophyll concentration. In the present paper, chlorophyll concentration has been deduced over the northeastern Arabian Sea and the southern Bay of Bengal using Ocean Color Monitor (OCM) data onboard Indian Remote Sensing Series Polar satellite (IRS-P4). The chlorophyll concentration is found to be higher...

A nutrientand carbon-rich, oxygen-poor benthic layer is observed in the lower 100m of the central and western Bay of Bengal, at depths between 3400 to 4000m. The observed ratios for the biogeochemical anomalies in the benthic layer water are similar to those observed for phytoplankton blooms in open oceans and hence suggest that the source of the high silica, phosphate, nitrate and carbon is li...

Trace metal contents in zooplankton samples were estimated as a part of the Marine Research–Living Resource program at 24 stations in the Bay of Bengal (November, 2002) and 29 stations in the Arabian Sea (September–October, 2003) during the Cruises 209 and 217 of the Fishery and Oceanographic Research Vessel Sagar Sampada. The average metal concentrations in the Bay of Bengal zooplankton (Fe, 1...

Paleoclimatic records from the Bay of Bengal are rare. We reconstruct the sea-surface temperature (SST) and salinity from paired δ18O and Mg/Ca measurements in planktonic foraminifera Globigerinoides ruber from the western Bay of Bengal core VM29-19. Our data suggest that SST and seawater δ18O (δOsw) were ~3°C colder and ~0.6‰ depleted, respectively, during the Last Glacial Maximum (LGM) compar...
