Abstract: | Variation of temperature and salinity in the lower 22 km stretch of the Gautami-Godavari estuary are reported during four different seasons; hot-weather, south-west monsoon, post-monsoon and winter seasons. The seasonal variation in temperature is small, with a high of about 30°C during hot-weather season and a low of about 26°C during winter season. Unlike temperatures, the salinities in the estuary show large seasonal fluctuations. During south-west monsoon surface salinities were low (0 to 8‰) due to high fresh water run off into the estuary. During hot-weather season surface salinities of 25 to 30‰ were observed due to negligible fresh water run off. |
