Country of Publication: United States Abstract: Data are summarized on the geological aspects of Eniwetok gathered over the last 40 years. The history of investigations may be divided into three periods: pre-1946, 1946-1964 and post-1964. The first period was one of discovery and initial exploration, focusing on surficial geologic features. Beginning in 1946, there was a significant increase in knowledge of atolls resulting from a series of comprehensive scientific studies which established baselines to assess effects from nuclear weapons testing conducted at Eniwetok between 1946 and 1958. From 1964 to the present, scientific studies have been of two types: those which have continued to address the problems conceptualized by earlier studies and those which have addressed the effects of the nuclear weapons testing. Studies of the hydrology of Eniwetok were initiated in 1972 to evaluate possible environmental effects of the proposed PACE high explosive craters on the ground-water resources of the islands.

The environment is also described, focusing on the lagoon, the reef flat, the seaward slope and the islands at Eniwetok. Man-made features that are evaluated include quarries which were excavated for building or road construction. A number of craters which remain from nuclear weapons testing are discussed.
