OSTI ID:7096022
During 1975 and 1976 a total of eight manned submersible dives with DSRV ALVIN were carried out in a relatively small region of the Atlantic 2800m radioactive waste dumpsite and were centered at 38 degrees 30'N and 72 degrees 09'W. Six other dives were distributed through the northern part of Deepwater Dumpsite 106 (DWD-106) near the boundary of the continental rise/continental slope. One of the primary purposes of these dives was to observe the geological conditions in this disposal region slightly south of the Hudson submarine Canyon. The lower continental slope was found to be incised by submarine canyons debouching into the northern side of DWD-106. The upper continental rise was incised by narrow meandering channels. One of these channels passed through the radioactive waste dumpsite and was surveyed in detail. On the upper continental rise the local terrain was relatively flat but studded with numerous tracks, trails, holes, and mounds of biological orgin. The sediment carpet was composed of a grapy silty-clay. Detailed mineralogical analysis was performed.
