There are many excellant sources of seismic data, all in the public domain. There is no one place that provides anything close to a complete inventory.

SPOT -- This Michigan Tech site lists sources for a variety of data sets and types of data volumes for use in education and research.

ASP_LDEO -- Our partner seismic portal at Lamont-Doherty Earth Observatory has many resources. They concentrate on field data but also have extensive collections of single-channel data. They also have freely-available global interpretation tools called GeoMapApp (map-based) and Virtual Ocean (a globe-based 3D tool).

USGS NAMSS -- The United States Geological Survey has a large collection of data collected by USGS and very high quality data from several geophysical contractors, all in the public domain. While the collection is focused on U.S. EEZ, it is a worldwide data base.

JAMSTEC -- This site provides information on IFREE (Institute for Research on Earth Evoluiton) seismic programs and information for data inquiries.

UCSD SIOSEIS -- This site provides access to a large number of cruises mostly with Scripps Institution of Oceanography investigators dating back to 1977. The legecy data is being moved into the UTIG_ASP. This site was under the direction of Paul Henkart, who also supported the SIOSEIS processing package.

IRIS -- The Incorporated Research Institutions for Seismology is mostly an earthquake data center but also has a number of important seismic reflection data sets.

NGDC -- The U.S. National Geophysical Data Center in Boulder, Colorado is the primary long-term archive for U.S. geophysical data. They act as the coordinating agency working closely with the USGS and academic data systems and institutions. They have important digital data but mostly have original or scanned data from images.

UNEP -- This Norway site, the UNEP Shelf Program, supports the United Nations extended continental shelf program for developing countries. It provides a mapping interface to identify seismic and related data residing in other data centers.
