Field Activity 2018-361-FA

Identifier 2018-361-FA
Purpose Florida Mapping Project: TBD
Location Cedar Key, Florida
Summary 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.
Info derived Processed XYZ mulitbeam bathymetry data points referenced to the ellipsoid and a water datum, digital elevation model, and subbottom profiles
Comments This FAN was completed in 2 Legs due to weather and an additional seismic survey was conducted on 05/30/19. Leg 1 = 11/26/2018 to 12/1/2018 Leg 2 = 12/9/2018 to 12/14/2018
