Status: Completed
Organization(s): USGS, St. Petersburg Coastal and Marine Science Center
Funding Program(s):
Principal Investigator(s): Christopher Smith
Affiliate Investigator(s):
Information Specialist(s): Nancy DeWitt, Christopher Reich, Billy Reynolds
Data Type(s): Electro-Magnetic: Ground Penetrating Radar, Imagery: Photo, Location-Elevation: Navigation, Sampling: Geology, Sonar: Single Beam, Sonar: Sound Velocity, Time Series: Mooring (physical oceanography)
Scientific Purpose/Goals: Establish baseline bathymetry for repeated bathymetry surveys in the area. Data from the surveys will be used in an effort to identify and track sediment movement between the marsh and the channel environments.
Vehicle(s): Ford F-350 Dually - Silver (GSA)
Start Port/Location: Cypremort Point, LA
End Port/Location: Cypremort Point, LA
Start Date: 2013-01-13

Equipment Used: Ashtech Z-Xtreme DGPS, Valeport SVP, Knudsen Marine Echosounder 320, Ground Penetrating Radar (GPR), Push Corer, Camera, Digital, Hand Held, Choke Ring Antenna
Information to be Derived: Bathymetry data (x,y,z), base station data, differential navigation, shallow sub-bottom profile, sedimentary analysis, GPR profiles.
Summary of Activity and Data Gathered: Single-beam bathy lines (74); Knudsen sub-bottom lines (74), sound velocity profiles (22); 4-inch sediment push cores (3); Peat auger cores (2); Ponar sediment grab samples (4); GPR profile lines (15)

Notes: Operation personnel were used to design the single beam mount for the R/V Mako.
GPR data were unusable, due to attenuation caused by saltwater-intrusion.
Sediment Samples will be archived and are on the east wall of the SPCMSC Sed Lab as of July 18th, 2018.
