Worldwide Database of Analog Marine Seismics, Bathymetry, Magnetics, and Gravity Data

The Analog Marine Geophysical Underway data file consists primarily of seismic data and some bathymetry, magnetics, and gravity data. Most of the data are released to NGDC in microform packages; microfilm, microfiche exceptions include deep penetration seismic record sections and maps released in full or half scale. The data cover approximately 5 million miles of worldwide oceans and have been collected by various academic institutions, government agencies and foreign governments. Data are quality checked, master and backup copies produced and disseminated upon request. These seismic data include Lease Sale (LS) data which are a collection of marine geophysical data in a particular area and common depth point (CDP) data consisting of multichannel high-resolution underway seismic records. Shot-point navigation and occasionally annotated bathymetry accompany the seismic data. The data were released mainly from the US Geological Survey (USGS), and the Minerals Management Service (MMS). Output Media: sections, maps, 35-mm microfilm, magnetic tapes, text and microfiche. In most cases, the microfilm has been scanned and data available as tiff images.
