DUNEX was a collaborative community-led experiment that took place in the fall of 2021 along the Outer Banks of NC, with the goal of improving the understanding, observational techniques, and predictive capabilities for extreme storm processes and impacts within the coastal environment. At the USFWS PINWR site, cameras were deployed for about a month, from September 18 to October 24, 2021, during which several storms passed offshore of the site. The cameras were mounted on separate 7-meter (m) tall masts within the dune, facing northeast and offshore, in a stereo configuration with approximately 75% overlap in field of view, to measure shoreline water levels and coincident topographic beach profiles. Images were collected during daylight hours with two schemes: 1) both cameras recording at 1 Hertz (Hz) for 5 minutes (min) starting 10 min before the hour for stereo photogrammetric processing to measure topographic beach profiles, and 2) one camera recording at 2 Hz for 17 min starting at the top of the hour for producing snapshots and time-averaged image products used to measure wave runup. One such product is a "runup timestack", which are created by sampling a cross-shore array of pixels from an image through time as waves propagate towards and run up a beach. Runup timestacks store the red, green, and blue (RGB) pixel intensity as a function of the cross-shore position for the sampling time period. This data release is for camera 2 timestack imagery, including coordinates in image, local, and world reference frames, which allows for quantitative measurements to be made. This camera is part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. USGS researchers utilize the timestack imagery collected from this camera to remotely sense information such as wave runup. This camera is part of the USGS CoastCam network. To learn more about the DUNEX camera deployment visit, https://www.usgs.gov/centers/whcmsc/science/dunex-pea-island-experiment. Purpose: Data were obtained to measure wave runup along a cross-shore transect. These data are intended for science researchers, students, policy makers, and the public. These data can be further processed to calculate wave runup. To ensure that USGS St. Petersburg Coastal and Marine Science Center (SPCMSC) data management protocols were followed, a USGS Field Activity Number was assigned (FAN) for this camera imagery collection: 2021-340-FA. Additional information about this FAN is available on the Coastal and Marine Geoscience Data System (CMGDS): https://cmgds.marine.usgs.gov/fan_info.php?fan=2021-340-FA. Supplemental_Information: The bounding coordinates below represent the approximate limits of the cross-shore runup timestack. This dataset represents the timestack images (in Network Common Data Form format (netCDF, .nc) collected from the USGS CoastCam at DUNEX.

Images may be obscured by water droplets, insects, birds, salt, sand and dirt, poor visibility from adverse weather conditions or sun glare, and thus may not reflect the true state of the beach and ocean. Logical_Consistency_Report: Due to data storage limitations and closer proximity to the shoreline, timestacks were preferably created using camera 1 (c1). However, if the view was obscured in c1, then camera 2 (c2) was used instead. There were 26 instances when timestacks were collected by both cameras simultaneously at the beginning of the experiment. The selected camera was programmed to collect three-band images every hour during daylight hours and take video for approximately 17 minutes. A timestack image for the 17-minute period was created by sampling a single transect on the beach. Completeness_Report: The imagery represents a fixed location within the U.S. Fish and Wildlife Service Pea Island National Wildlife Refuge on the Outer Banks of North Carolina. Images may not be available every hour of operation due to camera malfunction. Images may be obscured by water droplets, insects, birds, salt, sand and dirt, poor visibility from adverse weather conditions or sun glare, and thus may not reflect the true state of the beach and ocean. Depending on the conditions, one camera (c1 or c2) was used to create hourly timestacks. There were 26 instances when timestacks were collected by both cameras simultaneously at the beginning of the experiment. This product is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal accuracy of the camera's external orientation was verified using data collected in field activity 2021-340-FA and processed with the CIRN Quantitative Coastal Imaging Toolbox (Bruder and Brodie, 2020). Extrinsic calibration surveys for c2 were performed at the DUNEX site on September 18, 2021, and October 6, 2021. Horizontal accuracy was obtained by comparing the ground control points from the extrinsic calibration surveys in Over and others (2022) to user selected ground control points in the camera images. For the September 18, 2021, survey: the absolute mean x error is 0.07 meters, and the absolute mean y error is 0.30 meters. For the October 6, 2021, survey: the absolute mean x error is 0.011 meters, and the absolute mean y error is 0.1 meters.

Process_Step: Process_Description: To utilize the CoastCam imagery to make quantitative measurements, such as wave runup, both intrinsic orientation (IO) and extrinsic orientation (EO) calibration data is needed. Please refer to the dunex_c2_20210914_IO.zip, dunex_c2_20210918_EO.zip, and dunex_c2_20211006_EO.zip files and the dunex_c2_calibration_metadata record included in Brown and others (2024) for access to the IO and EO calibration data and more information on the calibration process. After the IO calibration was complete, the cameras were mounted on towers within the dunes at USFWS PINWR on 20210918. The cameras were connected to a control computer, powered by a solar panel and battery, and had a wireless network card. The control computer was connected to a hard drive to transfer the images upon collection.

However, if the view was obscured in c1, then camera 2 (c2) was used instead. There were 26 instances when timestacks were collected by both cameras simultaneously at the beginning of the experiment. The selected camera was programmed to collect three-band (RGB) images at 2 Hertz (Hz) for a total of 17 minutes (2040 images), every hour during daylight hours. The images from c2 included in this data release were collected from September 18, 2021, to October 20, 2021. Each hour the camera was activated, a timestack image product was produced by sampling intensity values at a single transect of pixels, defined by (U,V) pixel coordinates, from the 2040 images and saved in Tag Image File Format (.tiff). The (U,V) sampling locations were determined by identifying a cross-shore transect of locations in a local horizontal (X,Y) coordinate system, which aligned perpendicular to the local shoreline orientation. The elevation of samples was chosen as Z = 0 m NAVD88, which is an elevation assumed to be near the water line. XYZ-sampling locations were projected into (U,V) image coordinates following established methods (Bruder and Brodie, 2020; Palmsten and Brodie, 2022) and using the camera calibration information (Brown and others, 2024). To create the timestacks, the raw images were saved on the control computer s hard drive, then processed locally to produce one timestack per hour.

The topographic-bathymetric surface was developed from GNSS survey data collected within the field of view of the camera (Over and others, 2024). The point data were interpolated onto a grid using a scattered interpolation method. The local (X,Y) coordinates were rotated and translated into UTM coordinates using information describing the local origin and rotation angle for the DUNEX site, where the horizontal reference frame (X,Y) was NAD83(2011)/UTM Zone 18N. The (X,Y) coordinates were also translated from UTM to WGS84 latitude and longitude coordinates using the UTM Python library version 0.7.0.

Each netCDF file includes the timestack image; the sampling locations in (1) UV image coordinates, (2) XY UTM coordinates, (3) XY local coordinates, and (4) latitude and longitude coordinates; the Z-elevation coordinates projected onto the beach surface; and the times of collection. The timestack image was stored as a three-dimensional array of RGB pixel intensity values. The sampling locations were stored as two-dimensional arrays. The Z-elevation coordinates were stored as a one-dimensional array. The times of the collection, sampled at 2 Hz, were stored as a one-dimensional array, where each index of the array contained a time represented as epoch time, seconds elapsed since 00:00:00 UTC on January 1, 1970. Additional metadata was included in the netCDF files as global and variable attributes using the Climate and Forecast (CF)-compliant metadata convention (version CF-1.6). These attributes describe the data collection, as well as how the different coordinate systems are used within the data.
