2016年田辺湾における水温・塩分濃度観測

Abstract

The annual intensive field observations have been conducted using Tanabe-Nakashima observation tower by research group of Shirahama oceanographic observatory in Tanabe bay, Wakayama prefecture. In this study, we have conducted CTD (Conductivity (salinity)-Temperature-Depth) measurements supplementarily in the same bay area during the same period as the annual intensive observations. Those CTD results showed seasonal variations of water temperature and salinity, such as thermocline and density stratification which were observed at many points in Tanabe bay and freshwater entering from neighboring rivers. This paper reports our observation activities in 2016 and shows CTD results and three-dimensional structures of water temperature and salinity based on observed data.
