Author: Allen M. Hittelman Publisher: ISBN: Category : Marine geophysics Languages : en Pages : 228
Book Description
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.

Book Description
"This report describes the Earthquake Intensity File (also called the Earthquake Effect File), a unique data base that the National Geophysical Data Center (NGDC) has been developing for several years. The file now contains more than 137,000 reports on about 21,000 earthquakes that affected the United States from 1638 through 1980"--Description of file

Book Description
"This catalog summarizes geophysical and geological data available for the National Petroleum Reserve in Alaska (NPRA). Although the geographical scope of the data in this catalog is limited, similar data bases for other areas of interest to the exploration community also are archived by NGDC. Data holdings include those from the disciplines of seismics (reflection and refraction), gravity, magnetics, topography, well logs, geothermics, and earthquake seismology. NGDC encourages private industry initiatives in the use of these data, and welcomes cooperative projects with governmental agencies, non-profit organizations, and universities"--Foreword
