Summary of Activity and Data Gathered: The USGS surveyed two areas in Woods Hole, MA to test the capabilities of a multibeam echo sounder. Eel Pond, the safe harbor in Woods Hole as well as the area around the Woods Hole Oceanographic Institution (WHOI) dock were surveyed using the USGS Woods Hole Reson T20R multibeam echo sounder on 11-10-2021 aboard the R/V Rafeal. Depth soundings as well as acoustic backscatter were collected using the T20R, sound velocity of the water column was collected using an AML-3 sound velocity profiler.

| Survey Equipment | Survey Info | Data Type(s) | Data Collected |
|---|---|---|---|
| POS-MV | Vessel navigation and attitude data were acquired using an Applanix POS MV Wavemaster (model 220, V5) located in the Rafael cabin, with data coming in from an inertial measurement unit and two GNSS antennas. Data were monitored using Applanix POSView software. | Navigation | |
| Sensor - SVP | Sound velocity profiles were collected by hand deploying the AML-3 sound velocity profiler over the aft port side gunwale of the Rafael. The profiler was lowered through the water column to the sea floor. | Sound Velocity | |
| Reson T20-P | Multibeam echo sounder (MBES) bathymetry and backscatter data were collected using dual-head Teledyne T20-R sonars connected to the topside Teledyne Integrated Dual Head (IDH) processor. The sonars were attached to a bracket mounted to a pole which was deployed over the aft starboard gunwale. Data from the sonars were transmitted via cables to a monitoring workstation located in the cabin of the Rafael. | Multibeam Water column reflectivity | 2021-037-FA_ResonT20R_Backscatter_50cm (Multibeam backscatter data collected in the vicinity of Woods Hole, Massachusetts, during USGS Field Activity 2021-037-FA using a dual-head Teledyne Seabat T20-R multibeam echo sounder (8-bit grayscale GeoTIFF, UTM Zone 19N, WGS 84, 50-cm resolution)) 2021-037-FA_ResonT20R_Bathymetry_50cm (Multibeam bathymetric data collected in the vicinity of Woods Hole, Massachusetts, during USGS Field Activity 2021-037-FA using a dual-head Teledyne Seabat T20-R multibeam echo sounder (32-bit GeoTIFF, UTM Zone 19N, WGS 84, GEOID 18 (MSL) Vertical Datum, 50cm resolution)) 2021-037-FA_ResonT20R_Tracklines (Trackline navigation collected in the vicinity of Woods Hole, Massachusetts, during USGS Field Activity 2021-037-FA using a dual-head Teledyne Seabat T20-R multibeam echo sounder (Esri polyline shapefile, UTM Zone 19N, WGS 84)) |
