Physicochemical parameters in Karwar coastal water, central West coast of India

Abstract

In present study an attempt was made to investigate the bottom water physicochemical characteristics of coastal inshore water at nine stations along the coast of Karwar, India. Bottom water temperatures varied from (24.0 °C to 33.0 °C.). Salinity values varied from (8ppt. to 36ppt.), and pH ranged from (7.0 to 8.35.), Variation in dissolved oxygen content was from (2.2 mg/l to 4.36 mg/l), the range of inorganic nutrients viz. nitrites, nitrates, phosphates and silicates were (0.99 μg/l to 2.69 μg/l), (0.3μg/l to (2.95μg/l), (0.35μg/lto2.88μg/l), (5.35μg/l to 256.45μg/l) respectively.
