View new CMGDS report form

Other ID: none

Status: Completed

Organization(s): USGS, St. Petersburg Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Richard Poore

Affiliate Investigator(s):

Information Specialist(s): Julie Bernier

Data Type(s): Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: Quantify subsidence and erosion in areas of historical wetland loss

Vehicle(s):

Start Port/Location: Sulphur, LA

End Port/Location: Sulphur, LA

Start Date: 2008-06-03

End Date: 2008-06-13

Equipment Used: GPS , Peat Corer, Tripods, Vibracorer

Information to be Derived: Sediment-surface elevations and stratigraphic analysis (especially, peat thickness and depth to the organic-clastic contact) will be used to estimate the magnitude and rate of subsidence and erosion between marsh and open-water core sites.

Summary of Activity and Data Gathered: Collected 23 vibracores and 87 push cores across 4 areas of historic wetland loss in Sabine NWR. Measured water depths at each core site and along transects between core sites.
