The U.S. Geological Survey (USGS) deployed seismic recorders at three sites during marine seismic reflection profiling of the southern Alaska margin conducted by EDGE, a consortium of academic investigators. The EDGE marine reflection profiles were acquired in July 1989 using a tuned 128 liter (7800 cu. in.) airgun array towed from a commercial seismic ship. Three three-component land stations deployed in southern Alaska continuously recorded the airgun signals produced by the reflection profiling at large offsets. This report describes the experiment, provides the locations and times of operation of the recorders, presents the data reduction scheme followed, and illustrates the wide-angle seismic data recorded by the USGS.
