Analysis of echo sounding data North-Central Pacific (and west North Atlantic). Final technical report, September 1, 1976--March 31, 1978. [Site selection for marine disposal of high-level radioactive wastes]
Recognizing the need to consider several potentially suitable sites for disposal of high-level radioactive wastes, a very preliminary search was made through available data for such sites in the North Pacific and West North Atlantic Oceans. The criteria used were: the site must be between high-productivity belts and outside of 200 mile limit; a minimum of 50 meters of sediment, preferably 100 to 150 meters; the sediment should be red clay with minimum or no biogenic components; the sediment should contain no unconformities; and no strong discontinuous internal reflectors; the area should have no tele-seismicity, be topographically subdued, have minimal bottom currents, have no or low economical potential (Mn nodules, etc.), and be large enough (1 to 2/sup 0/ on a side) to be feasible for disposal. Some of these criteria may need to be relaxed; others may need to be added. Seismic data were the basic information used to cull out potential areas, and there are very few areas that meet the criteria as interpreted seismically. Initial site specific data assessment reported included examination of all available geophysical/geological data in and around the MPG-1 area (approximately 29/sup 0/ to 31/sup 0/N; approximately 156/sup 0/ to 160/sup 0/W); a topographic relief was described and the disposition of the thin (less than 100 m) sediment blanket and the acoustic character was mapped. A 15-day cruise was conducted in the MPG-1 area aboard the R/V VEMA and included detailed seismic measurements and heatflow/coring experiments to discern the variability of these parameters.
