Abstract

Abstract

The analysis on the thermohaline structure and ecological characteristics of the Zhanjiang Bay and its estuary in autumn was based on the investigations of Chl a concentration, salinity and water temperature in October 2015. The study showed that the horizontal distribution of the salinity in the Zhanjiang Bay increased gradually from inner bay to outside bay, the Chl a concentration decreased gradually from inner bay to outside bay, the water temperature is higher in shallow area, and that in the bottom of estuary there was a "high salinity, low temperature and low chlorophyll" relatively stable structure of cold water mass. The formation of the water mass was due to the unique terrain structure of estuary. This characteristic promotes the regional water stratification. At the same time, the low transparency of the bottom water body confine the growth of phytoplankton at the bottom of estuary.
