Description:
Abstract:
The data in this release re-map the beach and nearshore environment at Head of the Meadow Beach in Truro, MA and provide updated environmental context for the 2020 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. This is related to the field activity 2022-015-FA and a collaboration with the National Park Service at Cape Cod National Seashore to monitor the region that falls within the field of view of CoastCam CACO-01, which are two video cameras aimed at the beach. In March and April 2023, U.S. Geological Survey and Woods Hole Oceanographic Institute (WHOI) scientists conducted field surveys to collect topographic and bathymetric data. Images of the beach for use in structure-from-motion were taken with a camera (SONY a6000) and a post-processed kinematic (PPK) system attached to a helium powered balloon-kite (Helikite). High-precision GPS targets (AeroPoints) and numbered black and white tarps were used as ground control points. Bathymetry was collected in the nearshore using a single-beam echosounder mounted on a surf capable self-righting electric autonomous surface vehicle. Agisoft Metashape (v. 1.8.1) was used to create a digital surface model and orthomosaic with the collected imagery.
Purpose:
These data may be used as a high-resolution bathymetry dataset of Head of the Meadow Beach to observe conditions and change over time and to validate the CoastCam.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
No official quality control (QC) test was performed, but all depth values are internally consistent in relation to each other and are comparable to values of published bathymetry in the area (see over and others, 2021;2022). The product is interpolated and small-scale bathymetry features are not resolved. The actual vertical values may be much less accurate between tracklines. Yaw, pitch, and roll, are not taken into account due to the wide beamwidth, for more processing information see Francis and Traykovski, (2021).
Logical_Consistency_Report:
The raster file represents single beam echo-sounder bathymetry data collected by Peter Traykovski (WHOI). These data are a combination of post-processed kinematic (PPK) elevations collected using a GNSS receiver (EMLID Reach M2) and soundings from a Cerulean s500 single beam echosounder mounted on a self-righting autonomous surface vehicle. PPK data were corrected to an onshore base station (JAVA Triumph). The GNSS antenna is offset from the echo-sounder by 0.25 m (referred to as Antenna_Z_Offset), and this is taken into account when calculating the depth in the trackline and echosounder variables (see Processing Steps).
Completeness_Report:
Collected data were edited for erroneous soundings before being incorporated into the final bathymetric grid, the mask prevents extrapolation of data beyond the bounds but does not exclude any data. The CSV of raw PPK and echosounder values have been edited to remove returns at the beginning and end of the survey when the Autonomous Surface Vehicle (ASV) was on land.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Navigation information was acquired from the GNSS receiver in PPK mode with a multi-band GNSS antenna that has a theoretical horizontal accuracy of 1-5 cm and average reported xy standard deviation(SD) of 4.2 cm.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The location information was acquired from the GNSS receiver in PPK mode with a multi-band GNSS antenna with a theoretical horizontal accuracy of 1-5 cm and average reported z SD of 5.5 cm. The navigational accuracies do not represent the accuracy of the derived bathymetric soundings. The vertical accuracy of the raw data in water depths of 10 meters or less, based on industry standard system specifications for 450 and 500 kHz transmit frequencies, is 5-10 cm. Individual point errors (20-30% of points) due to extreme movement of the ASV could be as high as 10 cm, but process steps to interpolate and fit the raster remove a large portion of varaibility.
Lineage:
Process_Step:
Process_Description:
The single-beam bathymetry data were collected by launching the ASV Yellowfin into the water from the surf zone. Yellowfin is equipped with a Cerulean s500 echosounder and collects single-beam data and has an EMLID Reach M2 GPS for positioning data. The boat was controlled near the shore by Peter Traykovski and put on auto-pilot using predetermined tracklines for longer transects offshore. A base station was set-up on reference mark HOM RM1 for the duration of the survey. The raw bathymetry data was processed with the following steps: 1.Parsed the echosounder data (NMEA GPS Puck, Time, and Echosounder range) into MATLAB (v. 2020b) using MATLAB Scripts developed by Peter Traykovski at WHOI - see contact below 2. Post Processed Kinematic (PPK) GNSS data from the ASV was corrected using the base station (Java Triumph-1) data in Emlid Studio (Version 1.4) using the datum NAD83(2011) and then Geoid 18 for the vertical datum NAVD88. A projection for UTM Zone 19N was also specified to get the Easting and Northing information. 3. Refined time alignment to account for any small time delays between GPS data and echosounder data collection. This is accomplished using the time lagged cross correlation of echosounder range and PPK GNSS altitude in locations with a relatively flat bottom. The resulting time shift was 36 seconds. The GPS measures vertical fluctuation of the boat due to waves and these fluctuations are also visible in echosounder data. Outliers in the eachosunder data were removed using a despiking function. The equation in Step 5 removes the vertical fluctuation due to waves from the echosounder data leaving only true bathymetry if GPS and the echosounder are well synced. The lagged cross correlation processing ensures they are synced optimally. 4. The PPK GNSS elevation (GPS_z) positions (collected at a higher frequency than the echosounder) were interpolated to the time of echosounder samples (Echo_z) with the MATLAB function interp1 (linear interpolation). These interpolated data are available in 2023011FA_Truro_raw_bathymetry.csv 5. Calculated sea floor elevation with reference to the NAVD88 datum in meters using the following equation: Seafloor_z (Depth) = -Echo_z + GPS_z - Antenna_Z_Offset; Antenna_Z_Offset = 0.25 m was the offset from the GNSS antenna to the echosounder transducer on the z-axis of the ASV. 6. Gridded Seafloor_z values onto 1 m resolution UTM eastings, northings using MATLAB file exchange script regularizedata3d by Jamal (2020), a cubic interpolation with the optimum smoothness coefficient determined by a Monte Carlo optimization procedure for the data regularization. Regularizedata3d entailed removing one cross-shore line of data from the processing and adjusting the smoothness parameter so the overall surface fit best fits the removed data. The process was then repeated for all the lines of data. The optimized smoothing parameter was used with all the data for the final processing. 7. The MATLAB function 'roipoly' returned the mask as a binary image, which sets pixels inside the region of interest (ROI) to 1 and pixels outside the ROI to 0. The boundary was developed so that there were no extrapolated bathymetry data outside the tracklines. The masks extent was the convex hull of the tracklines positions (x,y) and a bounding z coordinate of 0.3 represented the surface in reference to NAVD88 in meters. 8. Exported gridded 1 m data in NAD83(2011)/UTM Zone 19N in NAVD88 meters as a GeoTIFF: 2023011_Truro_bathymetry_UTM19N_NAVD88_1m.tif. Note that using NAVD88 as a height, means that the depths are not true depths but the elevation of the seafloor above or below the geoid.
