Scientific Purpose/Goals: Document several centuries of environmental and sedimentological changes in Mobile Bay caused by natural and anthropogenic forces.
Vehicle(s):
Start Port/Location: TBD
End Port/Location: TBD
Start Date: 2010-08-04
End Date: 2010-08-08
Equipment Used: Vibracorer, Gravity Corer, Camera, Digital, Hand Held, Box Corer, GPS , Surface grab sampler
Information to be Derived: Ground-truth seismic data, investigation of shallow geologic framework, sediment grain size analysis, identification of Foraminifera presence and abundance and determine lithostratigraphic unit contact boundaries.
Summary of Activity and Data Gathered: Approximately 22 cores (10 vibracores, 2-3 gravity cores and 6-7 box cores) will be collected in the field and examined by both the USGS SPCMSC and WHCMSC; all seismic processing will be performed in Woods Hole, MA.
