Abstract :
European Space Agency (ESA), the World over Scientific organization, North Atlantic Treaty Organization (NATO), National Aeronautics and Space Administration (NASA) and WOrld Meteorological Organization are deeply concerned with the dis-balances caused to a significant extent due to human interference in the natural make-up of earth´s ecosystem. In particular, the ozone layer depletion (OLD) over the South Pole is already a serious hazard. The principal long-term effect of OLD appears to be an increase in the UV radiation reaching the earth. In our earlier findings on OLD have been reported and the effects could be observed using the data obtained from a ground based instrument known as Dobson Spectrophotometer installed at GC Quetta Pakistan. We have also computed UV flux reaching Arabian Sea due to the OLD. Then we have presented correlation structures of the population dynamics of marine organisms (fish yield and others) with the intensity of UV flux. The results are compared with the data acquired from Total Ozone Mapping Spectrometer (TOMS) Nimbus -7.
