Field Activity 2005-302-FA

Identifier 2005-302-FA
Purpose To conduct a high resolution single-beam bathymetric survey from Belle Pass to Caminada Pass that reoccupies tracklines from a similar bathymetric survey conducted in 1989.
Location Port Fourchon, LA; Caminada Monroe Headland
Summary Collected 483 km of single-beam bathy data which translated into 155,477 xyz data points.
Info derived Base station GPS, Boat GPS, single-beam bathymetry data
Comments This is a retroactive FAN, the survey platform was the R/V Streeterville and the government vehicle used at the time was a chevy suburban - white. Vibracores collected on this cruise. 05BS01, 05BS02

Data types and categories

Data category: Location-Elevation, Sonar
Data type: Benchmarks, Navigation, Single Beam

Equipment used

Equipment Usage description Data types Datasets
Ashtech Z-Xtreme DGPS Benchmarks, Navigation (no data reported)
Collapsible Tripod Tripod was used to hold the choke ring antenna upon the benchmark at each static base location. Benchmarks, Navigation, Profiles, Transects (no data reported)
Choke Ring Antenna The satellite L1/L2 signals were received via the Ashtech choke-ring antennas for the base station and the boat. The Ashtech Z-Xtreme GPS receivers interpret the signals and record the information as binary files. Benchmarks, Navigation (no data reported)
Marimatech Echosounder This instrument did not collect individual files; rather it was streaming depth below transducer via the E-SEA.dll driver into the HYPACK acquisition software. The strings of data are time stamped and located in the RAW HYPACK files. Example of data string: EC2 2 53549.473 2.210 0.000. Single Beam (no data reported)
TSS DMS-05 Motion Sensor This instrument did not collet individual files; rather it was streaming boat motion (heave, roll, and pitch) via the TSS320.dll driver into the HYPACK acquisition software. The strings of data are time stamped and located in the RAW HYPACK files. Example of data string: HCP 0 40073.584 -0.020 1.680 3.110. Interferometric, Single Beam (no data reported)
