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.
