Abstract

Diurnal fluctuations of physico-chem. factors were studied at 2 h interval over a period of 12 h at a fixed location in the Mulki estuary during pre-monsoon, post-monsoon, and monsoon seasons. Higher water temp. 30.5°C during the afternoon hours and lower temp. 20.50°C during the morning hours were recorded generally. Maximum range of dissolved oxygen 5.66 mL was recorded in post-monsoon season and min. 3.62 during pre-monsoon season. Dissolved oxygen (DO) concn. did not show any marked variations with that rhythm. Diurnal variation in salinity was min. during ebb tide while it was max. during flood tide in all the seasons. Ammonia, phosphate silicate concns. did not show any marked variation with tidal whereas nitrate-nitrogen and nitrate-nitrogen concns. were higher during ebb tide than flood tide during all seasons.
