Description:
Abstract:
The data in this part of the release characterize the beach and nearshore environment at the USGS DUring Nearshore Event eXperiment (DUNEX) site on Pea Island National Wildlife Refuge (PINWR) and at the Basnight Bridge (BB), NC. In November 2020, April, September, and October 2021, USGS and Woods Hole Oceanographic Institute (WHOI) scientists conducted multiple field surveys to collect a topobathy elevation time series. Bathymetry for topobathy products was collected in the nearshore using a single-beam echosounder mounted on a surf capable self-righting electric autonomous survey vehicle. Topography is produced using GPS walking surveys or structure-from-motion (SfM) with the imagery and ground control point data provided in the larger citation. DUNEX is a multi-agency, academic, and non-governmental organization collaborative community experiment designed to study nearshore coastal processes during storm events. USGS participation in DUNEX will contribute new measurements and models that will increase our understanding of storm impacts to coastal environments, including hazards to humans and infrastructure and changes in landscape and natural habitats. Collected data are part of field activity 2021-029-FA and donated data 2020-024-DD and are related to field activity 2021-028-FA and 2021-032-FA.
Purpose:
Topobathy dataset was aquired to observe change over time from the dune to the nearshore.
Supplemental_Information:
Topobathy products are the interpolated topography (SfM or walking survey) data and the single beach echosounder bathymetry data in the larger citation section of the release. For more information about the data, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2020-024-DD and https://cmgds.marine.usgs.gov/fan_info.php?fan=2021-029-FA.

Attribute_Accuracy:
Attribute_Accuracy_Report:
All elevation values are internally consistent in relation to each other and are comparable to values of published topobathy in the area (e.g. 2022 USGS CoNED Topobathy DEM (1851 - 2020): Coastal Carolinas, available at https://www.fisheries.noaa.gov/inport/item/67013, accessed May 18, 2022).
Logical_Consistency_Report:
These grids represent merged grids of single beam echo-sounder bathymetry data collected by Peter Traykovski (WHOI) and collected topographic data from the larger citation. Raw data is provided in the larger citation.
Completeness_Report:
Not all combinations of topography and bathymetry were merged from the raw data. The best coverage and completeness of the topography and bathymetry collected within two days of each other were used to produce the merged products.

Process_Step:
Process_Description:
The bathymetry and topography data are provided in the larger citation. Data are merged using the following steps. 1. The data (x,y,z) from the DSM and Bathy grids were combined with the interpolation method regularizedata3d (bicubic interpolation) using a smoothness coefficient of 0.001 (appropriate for data with low noise where the input points nearly coincide with the output surface) by Jamal (2020). 2. The combined grid was then masked using 'roipoly' which returned the mask as a binary image, setting pixels inside the region of interest (ROI) polygon to 1 and pixels outside the ROI to 0. The boundary was determined by specifying the polygon vertices as the regularizedata3D outputs (x,y,z) from the previous step and prevented extrapolation beyond the tracklines of the Bathy and DSM extent. 3. The final merged GeoTIFF was created using the GRIDobj tool in the TopoToolbox (Schwanghart and Scherler, 2014) which used the interpolated grid and the mask from step 2 to create the final output. 4. Export gridded 1 m data in NAD83(2011)/UTM Zone 18N in NAVD88 meters, using Geoid 12B, as a GeoTIFF. 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. Schwanghart, W., Scherler, D.

There are seven topobathy grids represent elevation in meters relative to the NAVD88 datum. The cloud optimized GeoTIFFs have no-data values of -3.402823E38. The naming convention is as follows: the USGS field name 2020024DD or 2021029FA; location is Pea Island National Wildlife Refuge (PINWR) at either the DUNEX or Basnight Bridge (BB) site; product is Topobathy; resolution is 1-meter; and date is in MMDD-DD to provide context if data were collected on multiple days for the final grid.
