Abstract:

The journal of a cruise of RV CHAIN from Bermuda to Freetown, Sierra Leone during February and March, 1961, is the basis of this report. Location of observations are given. The portion of the Mid-Atlantic Ridge lying along the equator was surveyed from 10 to 19 degrees W, and new information concerning the slope and orientation of rift zones was obtained. A detailed bathymetric survey of the Romanche Trench was made. A continuous temperature-depth profile, from the surface to 100 meters, was made along the ships track with a thermistor chain. Surface shear was measured with pitotmeters mounted on the chain surface water velocity relative to the water velocity at the depth of the pitotmeter, to determine the strength and direction of the equatorial undercurrent.
