MULTICHANNEL COMMON DEPTH POINT (CDP) SEISMIC REFLECTION DATA

Seismic Data for Southeast Bering Sea, Alaska

Data Announcement 1977-U

A program initiated by the U.S. Geological Survey (USGS) has produced a number of multichannel common depth point (CDP) seismic reflection lines from the Alaskan coastal areas. The National Geophysical Data Center (now the National Centers for Environmental Information) of NOAA is making these data available to the public as they are released by USGS. This is to announce the availability of CDP seismic sections for several survey lines in the southeast Bering Sea, Alaska.

These CDP lines were recorded by the Research Vessel LEE in September 1975 and were processed by Dresser Olympic. These sections are being distributed in the form of sepia or blackline copies. While all of the data were processed using standard AGC techniques, approximately one-fourth of the sections also include amplitude recovery. The scale available is 3 in./sec and 20 traces/in; all of the lines include 24-fold summation. The shot point data are on microfiche.

DATA AVAILABILITY:

Data is available in digital, navigation, bathymetry, magnetics, and gravity on magnetic tape or CD-ROM. Data is available (per set) in sepia or blackline.
