Abstract:
High-quality seismic reflection data are essential to geological investigation of the offshore. Over the past thirty years the USGS has acquired approximately 12,000 km of 2D data off the west coast of the United States. During this same period the petroleum exploration industry acquired probably 30 to 50 times that amount. To date, these data have been proprietary and available for publishable research only with significant restrictions. Although the commercial value of these data has diminished as a result of technological advances and offshore development moratoria, these data continue to have great relevance and value to current and future scientific research efforts. The value and risk of loss of these data was recently the subject of a National Research Council report "Geoscience Data and Collections: National Resources in Peril" by the Committee on the Preservation of Geoscience Data and Collections, Committee on Earth Resources. Recently, two companies with perhaps the largest holdings of proprietary data off the US west coast, WestemGeco and ChevronTexaco, have offered to transfer more than 250,000 km to the USGS for the purpose of making those data publicly available for research and educational purposes. Extension of these offers to include data offshore Alaska and the east coast of the U.S. is under discussion. The data being offered are for the most part conventional 2D multichannel airgun seismic reflection acquired and processed according to standards of the mid 1970's and early 1980's. The data commonly were acquired using a 5-to-25 element tuned airgun source totaling 1,000 to 3,000 cubic inches; 24-fold to 48-fold stacking; 25-to-50 meter CDP interval; 6 second recording with 4 msec sampling; processed through stack and post-stack migration. The surveys were generally limited to the continental shelf, extending up to 150 miles offshore southern California. Line spacing is dense off southern California, and becomes sparser to the north. http://walrus.wr.usgs.gov/NAMSS/
