Abstract
In order to investigate the temporal variations of the current and temperature at 300 m in Suruga Bay, the current and temperature data obtained from a moored ADCP observation in the sea at the eastern part of the bay mouth were analyzed. Observed maximum current speed of the inflow and outflow were 57 cm/sec and 40 cm/sec, respectively. The mean current throughout the whole observing period was less than 1 cm/sec. The maximum and minimum observed temperature were 12.7°C and 7.0°C, respectively. The range of the temperature variation was as large as 5.7°C. Comparing with those values to those off Cape Muroto-misaki, those at Suruga Bay were 2.9°C higher for maximum, 1.1°C lower for minimum and 4°C larger for the range. Therefore, the deep sea water at 300 m in the bay can not be low temperature and constant.
