Provides a comprehensive review of techniques used to explore the oceans and examines what geophysical observations reveal about the structure and tectonics of the seabed and the Earth's interior. Exploration of the oceans using geophysical methods has had a profound effect on the way we view the structure of the earth and its behaviour through geological time. Geophysics has also played a vital role in the search for petroleum and other natural resources lying beneath the seabed. This volume looks at: * the means of locating observations accurately and determining in detail the morphology of the sea floor * the powerful seismic techniques for imaging the Earth's interior from shallow coasta...
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.
This volume contains most of the papers which were presented at the Interdisciplinary Symposium No. 4 "Geodetic Features of the Ocean Surface and their Implications" during the XVIII. General Assembly of the International Union of Geodesy and Geophysics (IUGG) in Hamburg, August 1983. The symposium was jointly sponsored by the International Associ ation of Geodesy (lAG) and the International Association for the Physi cal Sciences of the Ocean (IAPSO), and was as such one further step in animpQrtant line of international and interdisciplinary symposia, re lated to the field of Marine Geodesy. Originally the term "Marine Geodesy" was widely understood as "Geodesy in the Marine Environment" and...
