Organization(s): USGS, St. Petersburg Coastal and Marine Science Center
Affiliate Investigator(s): Robert Morton
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
Start Port/Location: Leeville/Port Fourchon, LA
End Port/Location: Leeville/Port Fourchon, LA
Start Date: 2007-10-07
End Date: 2007-10-11
Equipment Used: Vibracorer, Peat Corer, Tripods, GPS
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 25 vibracores and 10 push cores from 3 study areas between Leeville and Port Fourchon. Recorded water depths at each core site and along transects between core sites.
