During 7 days in the vicinity of 35/sup 0/30'N, 61/sup 0/00'W (Seabed Disposal Program mid-late, mid-gyre study area MPG-III) we carried out 1830 km of subbottom acoustic profiling and 2 camera lowerings, and took 7 standard piston cores, 3 large diameter piston cores, 9 large diameter gravity cores and 2 dredge hauls of surface sediment. Pore fluids were extracted from 3 gravity cores and 1 piston core and on-board physical property measurements were made on 2 large diameter piston cores and 1 large diameter gravity core. These data and samples will be used to assess the lateral homogeneity and recent geologic history of the area, as well as to compare the sorption and physical barrier properties of the sediments with deposits from the MPG I and II areas in the Pacific.
