Information Specialist(s):
Data Type(s): Seismics: Sparker, Location-Elevation: Navigation
Scientific Purpose/Goals: Obtain geologic information in order to map and define sand deposits in the territorial waters of the U.S. Virgin Islands.
Vehicle(s):
Start Port/Location:
End Port/Location:
Start Date: 1977-09-13
End Date: 1977-10-01
Equipment Used: Single channel hydrophone, Del Norte 26 sparker, Motorola Mini-Ranger III
Information to be Derived: Morphology;
Summary of Activity and Data Gathered: The records obtained were good to excellent. The upper 10 feet of the sediment column is blocked by the arrival of the bubble pulse. The surface of the platform is sand and carbonate rock which produces multiple reflections. Because of water depth, at least 100 ms of good record were obtained. Minisparker: 1270 km; Seismic Lines: 1A, 1B, 3-9, 11, 13-23, 24A, 25-35, 37-64, 83-100, 102, 102A, 110-123, and CB; Time Log: #57.
