This publication contains summary information on the digital marine geophysical data holdings of the National Geophysical and Solar-Terrestrial Data Center. The general description of the bathymetric, magnetic, and gravimetric data includes discussion on exchange formats, data sources, assimilation procedures, and geographic distribution. Data summaries are presented as trackline plots, a geographical listing (by 10-degree squares), and an institutional listing. Complementary data files, such as U.S. coastal bathymetry, analog marine geophysical data (i.e., - seismics), site survey data of the outer continental shelf, and marine geological data, are reviewed briefly.

"Seismograms provide the seismologist the most efficient means of 'looking' into the most inaccessible regions of the Earth--the Earth's interior. Geophysical studies based on seismograms have drawn a vivid picture of a planet that has a solid inner core about 1250-km radius, a fluid outer core about 3470-km radius, a mantle about 2900 km thick, and a crust about 30 km thick. Other studies have pinpointed areas of high earthquake risk, where the buildings in which we live and work must be constructed to resist damaging earthquake motion. Further, the methods devised to describe Earth's internal structure have been used by many others to search for rich deposits of oil and minerals beneath its surface and its oceans"--Introduction.

"Gravity data have many scientific applications, both on the surface of the Earth and in space. The data are used for computing gravitational models, which aid those searching for oil, gas, and minerals. Alone or in combination with other data (such as satellite, astrogeodetic, or geophysical), gravity data are used to calculate deflection of the vertical components, geoidal heights, gravity disturbance components, and datum shifts for orienting local geodetic datums to an Earth-centered world geodetic system. The data are also used for calibrating inertial navigation and guidance systems"--Introduction.

"This list of United States thermal spring locations and temperatures and accompanying maps have been compiled in the course of preparing the maps: (1) Geothermal Energy Resources of the Western United States by National Geophysical and Solar-Terrestrial Data Center, National Oceanic and Atmospheric Administration (NOAA) (Grim, 1977); (2) Geothermal Energy in the Western United States and Geothermal Energy in Alaska and Hawaii in the U.S. Geological Survey (USGS) Assessment of Geothermal Resources of the United States-7978 (Muffler, 1979); and (3) State maps in press and preparation for the State Coupled Resource Assessment Program, U.S. Department of Energy, Division of Geothermal Energy (DOE/DGE). The list is a compilation of compilations, mainly from Waring's (1965) monumental Thermal Springs of the United States and Other Countries of the World; a Summary, USGS GEOTHERM computer file of thermal spring and well data, and currently active DOE/DCE-sponsored thermal data collection by State agencies and other organizations"--Page 1.
