Book Description
The near-surface geology to a depth of 300 feet beneath several of the windward islands and reefs at Eniwetok Atoll was investigated during 1971 and 1972. Rotrary drilling (approximately 130 holes, 8000 lineal feet) and seismic refraction (approximately 50,000 feet of traverse) were the primary field methods employed. Samples, classified on the basis of physical characteristics, were assigned to one of the following descriptive lithologic units: Upper Sediment, Upper Limestone, Lower Sediment, or Lower Limestone. In all sections drilled, these units were found to be sequentially ordered with depth. Correlation between geologic cross sections and seismic refraction profiles for two islands studied in detail indicate an internally consistent lithologic structure to the depth investigated.

Book Description
Geologic and geophysical investigations of six nuclear craters on Eniwetok Atoll were conducted during Project EXPOE to determine probable pre-shot geology and material properties of the GZ sites; post-shot geology and material properties in and near the cratered areas; and crater parameters and blast-related effects.

Book Description
The purpose of the PEACE Program was to provide highly credible, multidisciplinary set of geologic, geophysical, and material-properties data in order to identify crater dimensions and features for two high-yield nuclear craters and to better understand the dynamic processes that initially formed these craters and that subsequently modified them. These data are essential to the Department of Defense to better understand the survivability of strategic defense systems in the event of a nuclear attack. Physical Stratigraphic Framework; Sr-Isotope Framework; Mineralogy; Organic Content; Insoluble Residues; Downhole Geophysical Logs; Borehole gravity Surveys; Seismic Reference Surveys; Benthic Samples; Additional Paleontologic Studies; Radiation Chemistry ; Additional Sea-Floor Observations; Crater Interpretation.
