Temperature Data from the Pacific Abyssal Water from the CIRCE, NOVA, SHOW, TRIPOD and ZETES Expeditions.

摘要

This report presents the Pacific abyssal water temperature data accumulated during heat flow measurements made by the Scripps Institution of Oceanography from 1966 to 1968. The cruises include TRIPOD (1966), ZETES (1966), SHOW (1966), NOVA (1967), and CIRCE (1968) expeditions. The heat flow measurements are carried out by using Bullard type instrument which is composed mainly of a probe, several sensing thermistors, and a recorder housed in the pressure case. These thermistors are located one meter apart on the probe to measure the relative temperature difference from which the vertical temperature gradient is computed. The thermal conductivity of the sediments is measured either from the gravity core or by an in situ thermal conductivity probe. A product of the thermal conductivity and the temperature gradient yields the heat flux through the ocean bottom at the station. (Author)
