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 text file represents approximately 26 kilometers of navigation and depth 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.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Navigation were acquired using a Humminbird 898c HD SI Combo Global Positioning System (GPS), using the Wide Area Augmentation System (WAAS), which is spatially accurate within 2 meters, horizontally.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Humminbird 898c HD SI Combo GPS/Fish Finder also collects depth values below the instrument transducer. Vertical accuracy of the raw data in water depths of 10 meters or less, based on industry standard system specifications for 83 and 200 kHz transmit frequencies, is 5-10 centimeters

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:
Extract trackline navigation values using SonarWiz6 from the raw data:
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, use channels 1 and 2).
2. Once the .DAT file is imported, select the Tools menu in SonarWiz6, and select CSF, convert CSF file to CSV. This will save all information from the sonar file to a temporary scratch comma separated value (CSV) text file.
3. Using Excel (or other tabular data software), extract the date, time, altitude, navigation (easting, northing of nadir line) from the scratch CSV file created in step 2 and save these values to a new temporary scratch CSV file.
4. The DGPS horizontal coordinates recorded by the Humminbird unit are based on the WGS84 ellipsoid (WGS84 G1762, ITRF2008). Using vdatum ( https://vdatum.noaa.gov ), transform the horizontal UTM Zone 19 WGS84 coordinates using the temporary scratch file created in step 3 to the NAD83 HARN UTM Zone 19 reference frame, and save these coordinates to a new file containing date, time, transformed trackline coordinates (nadir easting, nadir northing), and depth (2016-030-FA_navigation.csv).
5. Using the UNIX utility gawk (Mac OS X ver 10.13.4, GNU gawk v4.2.1) to extract every 25th navigation entry from the CSV file created in step 4 (corresponding to every 1 sec) to a CSV file for efficient grid processing (2016-030-FA_navigation_dec25.csv).
Command line: gawk 'BEGIN{count=0}{if(!(count % 25))print;count++}' 2016-030-FA_navigation.csv > 2016-030-FA_navigation_dec25.csv
