Observation pattern of water mass structure at Jeneberang river estuary

Abstract

This research is a field study conducted in the estuary Jeneberang river. The estuary, the transitional zone formed between the river environment and the marine environment. In this region, there is the mixing of seawater with fresh water that has its own uniqueness with fluctuating salinity. This research aims to see the pattern of salinity distribution and temperature in the area of Jeneberang estuary on the tide and receding conditions. Data retrieval channeled on the area of Jeneberang estuaries with a distance between points 200 m using the ADCP (Acoustic Doppler Current Profiler) and CTD (Conductivity Temperature Depth) tools. The results showed an increase in salinity at Jeneberang estuary, which was influenced by surface and river bed.
