Other ID: none

Status: Completed

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

Funding Program(s): Florida Coastal Mapping (GX.21.MN00.EQ590.00)

Principal Investigator(s): Cheryl Hapke

Affiliate Investigator(s):

Information Specialist(s): Nancy DeWitt, Andrew Farmer, Joseph Fredericks

Data Type(s): Location-Elevation: Navigation, Seismics: Bubble Gun, Sonar: Multibeam

Scientific Purpose/Goals: Florida Mapping Project: TBD

Vehicle(s): Ford F-350 Dually - Silver (GSA)

Start Port/Location: Cedar Key, FL

End Port/Location: Cedar Key, FL

Start Date: 2018-11-26

End Date: 2018-12-05

Equipment Used: Multibeam Bathymetry System, Along Track Reef Imaging System (ATRIS) - Shallow, Applanix POS-MV DGPS/IMU, Ashtech ProFlex 800 GNSS Receiver, Choke Ring Antenna, Collapsible Tripod, Bubble Pulser, Bubble Pulser Hydrophone Streamer Cable

Information to be Derived: Processed XYZ mulitbeam bathymetry data points referenced to the ellipsoid and a water datum, digital elevation model, and subbottom profiles

Summary of Activity and Data Gathered: On leg 1 and leg 2 data was successfully collected: multibeam bathymetry (~164 lines), navigation data (163.3 MB base; 6.38 GB rover), and SVP casts (116 profiles). On leg 2, bubble gun was deployed and successfully recorded 13 lines.
