Variation in the thermohaline front at the mouth of Tokyo Bay

Abstract

The generation, variation, and disappearance of the thermohaline front at the mouth of Tokyo Bay were investigated using water temperature data obtained by a commercial ferry boat in 1987. The thermohaline front was generated south of Kan-non-zaki in mid November 1987 after the beginning of sea-surface cooling. It moved northward to Kan-non-zaki until the end of the year. The thermohaline front was most intense in February and March and disappeared in late March 1987 when sea-surface warming began.
