During 10 days in the vicinity of 33$sup 0$20'N, 151$sup 0$00'W (MPG-2 area), three near-bottom current meters were deployed, the bathymetry and subbottom acoustic structure of the surrounding seafloor were determined, and sediment cores were collected for studies of artificial radionuclide distribution, geotechnical properties, geochemical properties, and to identify the character of shallow acoustic reflectors. Large volume water samples for artificial radionuclide studies and suspended sediment were also collected. These samples and data will supplement earlier material to be used in the evaluation of the central North Pacific as a potential site for the ultimate disposal of high-level reactor wastes. (auth
