Principal Investigator(s):
Affiliate Investigator(s): Robert Morton
Information Specialist(s): Julie Bernier
Data Type(s): Sampling: Biology, Sampling: Geology
Scientific Purpose/Goals: Quantify subsidence and erosion in areas of historical wetland loss
Vehicle(s):
Start Port/Location: Jean Lafitte or Ironton, LA
End Port/Location: Port Fourchon, LA
Start Date: 2007-09-04
End Date: 2007-09-14
Equipment Used: Peat Corer, 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 22 vibracores and 6 push cores from 2 study areas near Jean Lafitte. Recorded water depths at each core site and along transects between core sites.
