Industry Seismic Reflection Tracklines
Samuel Y. Johnson, Shawn V. Dadisman, and Susan B. Rhea

This map shows trackline locations of parts of four proprietary conventional industry seismic-reflection surveys that were conducted between 1967 and 1982 in the eastern Juan de Fuca Strait. These data were either donated to or purchased by the U.S. Geological Survey with variable restrictions attached regarding public accessibility and publication rights. All surveys used airgun sources and data were recorded for 4 or 5 seconds on multichannel streamers. Industry processing of the data sets varies between and within surveys. Stacked data are available for all profiles, and migrated sections are available for some profiles. Examples of these data include Figures 7, 8, and 14. Some profiles from these surveys, including lines from the eastern Juan de Fuca Strait and elsewhere in the Puget Sound region, have been published in Johnson and others (1994, 1996, 1999) and Pratt and others (1997).
