Potential applications of satellite remote sensing technique in oceanography and fisheries

Abstract

A wide range of data collection can be achieved by remote sensing in oceanography and fisheries which by conventional ship-board observation would take considerable time and effort. IRS 1 (Indian Remote Sensing Satellite 1), expected to be launched this year by ISRO, will form the first of a series of operational remote-sensing satellites in resources survey. The Joint Experiments Programme (JEP) for the development of suitable sensors in marine fisheries, organised by ISRQ in collaboration with CMFRI and FSI, enabled the development of suitable sensors in the estimation of chlorophyll and bioproductivity. In addition to the IRS Utilization Programme, SPOT, LANDSAT MSS and TM data also will be available for this. The major thrust from these studies will be on the structure and synoptic variability of oceanic fronts, observations on eddies, their formation and evolution, internal waves through panoramic Images, precipitation Intensity in oceanic areas, ocean currents by drifting buoys with transponders and distribution pattern of chlorophyll in coastal waters by means of differential spectra analysis of radiance. These parameters can provide considerable information to aid in forecasting, exploitation and management of fisheries which have been discussed In this account.
