Description:
Abstract:
The objectives of the survey were to provide bathymetric and sidescan sonar data for sediment transport studies and coastal change model development for ongoing studies of nearshore coastal dynamics along Sandwich Town Neck Beach, MA. Data collection equipment used for this investigation are mounted on an unmanned surface vehicle (USV) uniquely adapted from a commercially sold gas-powered kayak and termed the "jetyak". The jetyak design is the result of a collaborative effort between USGS and Woods Hole Oceanographic Institution (WHOI) scientists.
Purpose:
This image represents approximately 26 kilometers of sidescan sonar data collected in 2016. These data were collected by the Woods Hole Coastal and Marine Science Center during USGS field activity 2016-030-FA using a Humminbird 898c HD SI Combo GPS/Fish Finder remote sensing instrument (www.humminbird.com) that is rigidly mounted on the hull of the jetyak. These data can be used in conjunction with other geophysical and sample data to identify sea-floor morphology and sediment texture.

These data were collected using the USGS jetyak, a commercially sold gas-powered kayak built in upstate New York, running pre-planned lines perpendicular to the beach with a 20 meter line spacing. The jetyak has a roto-molded polyethylene hull and an air-cooled 7-horsepower four-stroke engine. It is propelled and steered by means of a water-drive. The boat will run for 8 to 10 hours on 3 gallons of gas at survey speeds of 2 to 6 knots. Modifications were made by USGS and WHOI scientists to make the jetyak autonomous. The two original manual controls (throttle and steering) are replaced by servos: automatic devices that use error-sensing feedback to correct performance, such as those employed in remote-control airplanes and satellite-tracking antennas. The servos are run by an onboard computer developed for aerial drones. This computer, a modified Arduino, includes Ardupilot software and a special circuit board that provides interfaces for the controls, radio, and Global Positioning System receiver (GPS). The only other modification is installation of a centrifugal clutch, which allows the engine to idle without moving the jetyak.
Onboard the Jetyak is a hull mounted Humminbird 898c HD SI Combo GPS Fish Finder that is used for GPS navigation and location in addition to collection of sidescan sonar data at 455 kHz, and depth (bathymetric) data at 83 and 200 kHz. Files are saved in a proprietary Humminbird .SON/.DAT paired data format, contact www.humminbird.com for details. A separate navigation GPS receiver mounted onboard the Jetyak is a Spectra Precision SP80 GNSS receiver (http://www.spectraprecision.com/eng/sp80.html#.WyQWYDNKjUI). This receiver is mounted on top of a pole 1.025 meters in length which is attached to the hull of the jetyak. This receiver is called the "rover", and saves information that will later be used in conjunction with base station established on the beach to calculate kinematic solutions for both the horizontal and vertical coordinates of the rover. The sidescan sonar, navigation, and bathymetry data were processed using Chesapeake Technology 64-bit SonarWiz6 version 6.05.0025 (www.chesapeaketech.com) and ArcGIS version 10.5 (www.esri.com).
Process_Step:
Process_Description:
Sidescan sonar data processing and mosaic steps using SonarWiz6:
1. Create a project (UTM-WGS84, Zone 19N, central meridian -69.0) and use all default import parameters for the Humminbird .DAT format in SonarWiz6 (use sensor heading, import 1024 samples per channel, channels 1 and 2).
2. Once the .DAT file is imported, select the file (right click) and set the processing options (settings): Enable EGN (empirical gain normalization using all sidescan sonar data pixel values and range from transducer), intensity 75; enable Nadir Filter, nadir angle 40; project sonar data using sensor heading checkbox selected.
3. After the processing settings are applied, select the sonar file (right click) and set the display range for port and stbd to 15 meters.
4. Then single click on the sonar file and set the color histogram datatype to sidescan (ch. 1 and 2), palette to gray, inverted, and manually stretched values of 79-149.
5. After processing completes, use the Export menu to save individual geo-images. In the resulting popup dialog, set the output file type to GeoTIFF, color resolution 24-bit, image resolution 1 meter/pixel, background color to white (255,255,255), checkbox selected for disable compression. The resulting GeoTIFF image is spatially mapped in the UTM 19N WGS84 projection.
6. Reproject the GeoTIFF created in step 5 from UTM zone 19N WGS84 to UTM zone 19N NAD83-HARN using the ArcCatalog Project Raster utility. The output horizontal datum used is NAD_1983_HARN_UTM_Zone_19N.

Overview_Description:
Entity_and_Attribute_Overview:
There are no text attributes associated with a binary GeoTIFF image. Data values within the GeoTIFF file are represented separately in 3 equal 8-bit bands (24-bit image) containing acoustic reflectivity values normalized to an 8-bit data range, and range in value from 0,0,0, to 254,254,254. Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values). The background color is set to 255,255,255 and can be turned off without removing data values.
