The data gathered during the study of the Enewetak craters are applicable to many scientific topics well beyond cratering mechanics and other related strategic concerns of the US DOD. These scientific topics include the geologic evolution of the Pacific Basin, the biologic and geologic history of a coral atoll, the fluctuation of sea level in response to glaciation and deglaciation, the diagenetic history of carbonate rocks in relation to sea-level changes and the differing substrate-water geochemistries thus produced, the speciation and migration of marine biotas, and the biostratigraphic succession of biotas through time and the calibration of these events with an absolute KEYWORDS EDB Item isotopic time scale, to name a few.

DATE (YYMMDD) LIMITATION CODE ABSTRACT Engineering] 9003454 (Japan). Faculty of 159-164 910300 UNL Radioactivity survey has been performed on samples taken from a fishing boat, the 5th Sumiyoshimaru. This boat has been presumed to be exposed to the fallout of Bikini hydrogen bomb test. Gamma-ray measurements have been carried out for six wood samples and two soil samples. KEYWORDS Higashi-Hiroshima Since the {sup 137}Cs concentration estimated for all samples were comparable to the fallout of the nuclear test, it was hard to judge whether the boat was definitely exposed to the Bikini fallout.
