| Purpose | Collect high-resolution single-channel seismic reflection data near Puerto Rico and the U.S. Virgin Islands. This endeavor was secondary to the collection of gravity data by the USGS-Menlo Park personnel for the Defense Mapping Agency (DMA). This report covers the seismic reflection aspects of the cruise. | ||||||||
| Location | U.S. Virgin Islands, Puerto Rico, United States, Caribbean Sea, North America, North Atlantic; | ||||||||
| Summary | Seismic reflection data gathered: Lines 35A, 35A-TRANS, 32, 32A-TRANS, 33, 33A-TRANS, 34, 34A-TRANS, 30, 52, 26, 26A-TRANS, 29, 28, 28A-TRANS, 28B, 28-WEST, 27, 27A-TRANS, 55, 53, 54B, 54A-TRANS, 16, 45, 45A-TRANS, 3, 3A-TRANS, 4, 4A-TRANS, 42, 42A-TRANS, 8, 8A-TRANS, 7, 6, 5, 5A-TRANS, 9, 9A-TRANS, 10/11, 10A, 12/13, 13A, 13A/B-TRANS, 14C, 14A-TRANS, 14B-TRANS, and 50. | ||||||||
| Comments | Cruise reports for Field Activities 85004, 85005 and 85007 detail the 3 legs of this project: LEG 2 - 02/28-03/11/1985 (FA 85004); LEG 3 - 03/15/-03/28/1985 (FA 85005); LEG 4 - 04/01-04/08/1985 (FA 85007). Original Center People field contained: Kathy Scanlon - Seismics. | ||||||||
