In July of 2008, the U.S. Geological Survey conducted geophysical surveys to investigate the geologic controls on island framework from Ship Island to Horn Island, Mississippi, for the Northern Gulf of Mexico (NGOM) Ecosystem Change and Hazard Susceptibility project. Funding was provided through the Geologic Framework and Holocene Coastal Evolution of the Mississippi-Alabama Region Subtask (http://ngom.er.usgs.gov/task2_2/index.php)
; this project is also part of a broader USGS study on Coastal Change and Transport (CCT). This report serves as an archive of unprocessed digital Chirp seismic reflection data, trackline maps, navigation files, GIS information, FACS logs, observer's logbook, and formal FGDC metadata. Gained digital images of the seismic profiles are also provided.
For more information on the seismic surveys see http://walrus.wr.usgs.gov/infobank/g/g108mi/html/g-1-08-mi.meta.html
These data are also available via GeoMapApp (http://www.geomapapp.org/
) and Virtual Ocean ( http://www.virtualocean.org/
) earth science exploration and visualization applications.
To archive all digital Chirp subbottom profile data and associated files collected during cruise 08CCT01.
The USGS St. Petersburg Coastal and Marine Science Center (SPCMSC) assigns a unique identifier to each cruise or field activity. For example, 08CCT01 tells us the data were collected in 2008 for research on Coastal Change and Transport (CCT) and the data were collected during the first field activity for that study in that calendar year.
