Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): David Twichell
Affiliate Investigator(s): USGS St. Petersburg
Information Specialist(s): David Twichell
Data Type(s): Sampling: Geology, Location-Elevation: Navigation
Scientific Purpose/Goals: Vibracoring in Apalachicola Bay to ground truth seismic data and reconstruct the late Holocene history of the bay.
Start Port/Location: Apalachicola, FL
End Port/Location: Apalachicola, FL
Start Date: 2007-05-22
End Date: 2007-05-26
Equipment Used: Alpine Vibracorer, GPS (wh)
Information to be Derived: Grain size analysis;Visual core descriptions and age dates;
Summary of Activity and Data Gathered: Twenty-four vibracores were collected from 23 different stations within Apalachicola Bay. Water depths for the stations ranged from 2.2 to 4.0 m. The core barrels were 6.1 m (20 ft) in length, and the recovered cores ranged from 2.6 m to 5.4 m.
