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.

Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.
