Abstract

Studies on the hydrological conditions off Karwar were undertaken on
board one of the vessels of I.N.P. during the years 1965 to 1967. The inshore
samples collected from surface, 10 m and bottom (15-31 m), showed quite distinct
demarlcation in the distribution of physico-chemical properties. The average
monthly values of pH fluctuated between 8.0 and 8.4. Dissolved oxygen reached
its maximum in the sub-surface layers. Saturation and supersaturation values
were frequently observed at 10 m and 15-31 m than that at surface, indicating the
zone of maximum photosynthesis below the surface waters. The distribution of
nutrient salts showed that they are concentrated at bottom
