Water Circulation at Man Nai Island, Rayong Province in year 2016

Abstract

Water currents were measured in the coastal areas of Man Nai Island in every two months of 2016, from February 2016 to January 2017, to be used as a basis for describing changes in marine ecosystems in this area. The results show that the currents are mainly influenced by the monsoonal winds, with the influence of tide and coastline as factors that make the currents more complex. Most current flows eastward or northeastward during the southwest monsoon and westward or southwestward during the northeast monsoon. The currents are complex and different from other seasons during the inter-monsoon periods when winds from many directions blow into the area. Keywords: water current, Man Island, monsoon
