Abstract : On GOSNOLD Cruise No. 73, 9 July - 6 August, 1965, a program of geophysical and geological research was conducted on the Blake Plateau in the vicinity of the proposed Sea Spider location. On the basis of a detailed topographic survey over a 6 x 7 mile area it was determined that the bottom was absolutely flat, with a decrease of 2 fathoms from north to south, and an average depth of 439.4 fm. Pipe dredge stations on a SE-NW traverse across the surveyed area yielded coarse, organic, calcareous sand. Current measurements using three different types of drogues indicated highly variable currents, reversing direction over a period of five days and ranging in velocity from 0.2 knots to 0.5 knots. Work on this leg of the cruise was completed with the installation of two marker buoys set on an E-W line near the center of the surveyed area. (Author)
