Satellite Remote Sensing of Chlorophyll-a Distribution in the Northeast Arabian Sea
نویسندگان
چکیده
The present paper discuss on spatial and temporal distribution of chlorophyll-a (Chl-a) in the coastal and offshore waters of northeastern Arabian Sea, using Advanced Earth Observation Satellite OCTS data. The Chla concentration found high all along the western Indian coastal waters, with significant variations at Gulf of Cambay and Gulf of Kutch regions, ranging from 0.05 to 4.0 mg m. Several intermittent eddies with a duration of 3 days to 4 weeks were observed in this season as a result of wind speed and circulation patterns with maximum Chl-a (4.0 mg m) at their centers. The coastal chlorophyll is observed to transfer in pole-ward direction coupled with eastern boundary current or West Indian Coastal current (WICC) and, the clockwise tendency of Coriolis effect apart from wind direction. Possible interactions between Chl-a measurements, eddies, Sea Surface Temperature (SST), wind speed and river water discharge are discussed.

Monthly variability of chlorophyll and associated physical parameters in the southwest Bay of Bengal water using remote sensing data
In the present paper, we have carried out analysis of surface chlorophyll-a concentration in the seas around India obtained using the Indian Remote Sensing satellite IRS-P4 Ocean Colour Monitor (OCM) data. The focus was given to southwest Bay of Bengal where such studies are scanty. The study portraits the chlorophyll-a pattern during July 1999-June 2000. The monthly sea surface temperature (SS...

Remote sensing has changed modern oceanography by proving synoptic periodic data which can be processed. Since the satellite data are usually too much and nonlinear, in most cases, it is difficult to distinguish the patterns from these images. In fact, SOM (Self-Organizing Maps) model is a type of ANN (Artificial Neural Network) that has the ability to distinguish the efficient patterns from th...
متن کاملComparison of chlorophyll distributions in the northeastern Arabian Sea and southern Bay of Bengal using IRS-P4 Ocean Color Monitor data
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...
