bursts and how Pacific Proving Grounds craters relate to
the basing and targeting of nuclear-weapon
$ystems and
related national defense issues. 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

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.

Since the

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. (author).
