unclassified
The Pacific Enewetak Atoll Crater Exploration
(PEACE)
Program was established to resolve a number of
questions for the Department of Defense (DOD) about the
geologic and material-properties parameters of two
craters
(KOA and OAK),
formed by near-surface bursts of
high-yield thermonuclear devices on the northern margin
of Enewetak Atoll, Marshall Islands, in 1958. The
multidisciplinary studies conducted by the USGS in
collaboration with other organizations during 1984
through 1987 were part of a much larger research
initiative by the DNA to better understand the dynamic
properties of strategic-scale nuclear bursts and the
relevance of the Pacific Proving Grounds
(PPG)
craters
to issues of strategic basing and targeting of nuclear
weapons. Major topics include: Borehole gravity;
Palentologic evidence for mixing; Electron paramagnetic
resonance studies; Bathymetric studies of OAK crater;
Constraints on densification and piping for OAK; and
801.
