chlorophyll-a concentration, sea surface heights, sea surface temperature, data

on vertical profiles of temperature and salinity from the ARGO drifting floats,

wind speed, the Dipole Mode Index, and historical data on sardine landings

were employed, to analyze physical-biological coupling in the western

Arabian Sea which is known for its vigorous eddy field affecting

characteristics of biological productivity. Summer and winter monsoons

impose different modes of mesoscale variability. In summer, the East Arabian

Current along with the currents of the Arabian Sea interior generates a dense

field of eddies, where as in winter, eddies become less developed and less

numerous. Therefore, the chlorophyll distribution is more heterogeneous

spatially and more variable temporally during summer monsoon. Interannual

changes of eddy field bear footprints of the impact of basin-scale atmospheric

anomaly (the Indian Ocean Dipole). Spatial-temporal characteristics of the

eddy field are valuable tools in understanding seasonal and interannual

fluctuations of sardine landings contributing ~ 50% to the fishery in the

region},
