Abstract

Measurements of vertical thermal structure were made by using a thermister chain at the fishing ground of the Sagami-Bay head for a period from July 30 to September 2, 1986. The temperature sensors were suspended from 20m to 40m depths at 2m interval. The low frequency and tidal fluctuations, particularly semidiurnal period, were dominant in these records. The temperature decrease of 2.5-4.0 degrees was found in the low-pass filtered records in the middle of August and lasted about ten days. Such phenomena were observed near the bay mouth as well, and seem to be caused by the appearance of the low-temperature water mass through Oshima West Channel south of the Izu Peninsula. The tidal temperature fluctuations can be considered to be due to the internal tides and maximum range of the temperature variations at each depth reach 2.0-2.5 degrees for semidiurnal constituents.
