Summarizes findings of the deep sea drilling project at Scripps Institute of Oceanology. Results of Atlantic and Pacific Ocean drillings in terms of the composition and properties of the sea floor are discussed. (CP)

Discusses the goals of the ocean drilling under the International Phase of Ocean Drilling, which include sampling of the ocean crust at great depths and sampling of the sedimentary sequence of active and passive continental margins. (MLH)

Describes activities of Geodynamics Project of the Federal Council on Science and Technology, such as the application of multichannel seismic-reflection techniques to study the nature of the deep crust and upper mantle. (MLH)

Drilling during 1978 focused on three major geologic problems: the nature and origin of the oceanic crust, the nature and geologic history of the active continental margins, and the oceanic paleoenvironment. (Author/BB)

The growing interest in evaporite geology in 1978 is shown by the number of short courses, meetings, and symposiums that were held on various aspects of evaporites. (BB)

Research in carbonate geology over the last year continued many trends prevalent the year before, not the least of which has been the study of modern carbonate platform margins. (Author/BB)

Reviews the past year during which the emphasis was one of rethinking the goals of future investigation of the ocean floor by drilling. Scientific and technical needs are discussed and planning procedures included. (MA)

An overview is presented of major research studies, scientific events, and issues of concern during 1981 in the field of geology. Thirty-four areas are reviewed ranging from archeological geology to volcanology. (DC)
