Title:
Coring, Vibracore data of field activity 87039 (B-12-87-LA) in Chandeleur Islands, Northern Gulf of Mexico - Louisiana, Mississippi from 09/15/1987 to 09/24/1987
Abstract:
United States Geological Survey, Florida Integrated Science Center, Saint Petersburg (Coastal and Marine Geology Program),United States Geological Survey, Reston, Virginia,Louisiana Geological Survey,Alpine Ocean Seismic Surveys. Chief Scientists: Jeff Williams, Jack Kindinger, Shea Penland, John Suter. Coring, Vibracore data (navigation) of field activity 87039 (B-12-87-LA) in Chandeleur Islands, Northern Gulf of Mexico - Louisiana, Mississippi from 09/15/1987 to 09/24/1987, <http://walrus.wr.usgs.gov/infobank/b/b1287la/html/b-12-87-la.meta.html>.
Supplemental_Information:

Equipment Used -
navigation data directory exists
Notes -
This cruise is an up date to USGS
CMG 87039. 87039 data archive included some of the offshore gulf side of the
islands cores (32) and this 87CI updates the previous archive with near- and
off- shore cores on the bay and gulf sides of the Chandeleur Islands, Breton
Island and Curlew Island. A total of 71 cores are referenced in a U.S.
Geological Survey Data Series. (*Data Series in progress). The crew, dates and
platform information was assumed to be the same as 87039. All 1987 Chandeleur
Island area cores are named CI-87-core #, and 4 cores are named CI-87-core
#-CURLEW, a complete reference of the cores are in a U.S. Geological Survey
Data Series. (*Data Series in progress). The combined cruises completed
transects on the gulf and bay sides of the islands.
Jeff Williams Notes: Collect 40-ft. long continuous vibracores at sites selected from hi-res seismic profiles collected in a survey in June 1987. Interpretation of the cores and seismic profiles will be used to determine the stratigraphy and structure of the shallow subbottom of the region. Long-term purpose of program is to locate and identify potential offshore sand borrow areas for beach replenishment projects.
