Title:
10BIM06_Marine_core_locations: Cat Island Marine Core Locations from field activity 10BIM06
Abstract:
Scientists from the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center (SPCMSC), in collaboration with the U.S. Army Corps of Engineers (USACE), conducted geophysical and sedimentological surveys around Cat Island, the westernmost island in the Mississippi-Alabama barrier island chain. The objectives of the study were to understand the geologic evolution of Cat Island relative to other barrier islands in the northern Gulf of Mexico and to identify relationships between the geologic history, present day morphology, and sediment distribution. This report serves as an archive of terrestrial and marine sediment vibracores collected August 4-6 and October 20-22, 2010. Geographic Information System (GIS) data products include marine and terrestrial core locations and 2007 shoreline. Additional files included: marine and terrestrial core description logs, core photos, grain-size analysis, optically stimulated luminescence (OSL) dating and Carbon-14 dating locations and results, Field Activity Collection System (FACS) logs, and formal Federal Geographic Data Committee (FDGC) metadata (data products and downloads).

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The positional accuracy of the vibracores is determined by the navigational data for the survey. These vibracore data have not been independently verified for accuracy.
  2. How accurate are the geographic locations?
    Locations were collected on the RV Gilbert using a Garmin model 3210 GPS unit.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    This is a complete processed marine vibracore location file for the field site.
  5. How consistent are the relationships among the observations, including topology?
    These vibracore locations represent the location where marine cores were collected in the field. They represent marine vibracore data coverage for the 2010 Cat Island survey.
