Topography data were collected on foot with survey-grade global navigation satellite system (GNSS) receivers mounted on backpacks and with an all-terrain vehicle (ATV) using a GNSS receiver mounted at a measured height above the ground. Purpose: Data were obtained to document changes in shoreline position and coastal morphology as they relate to episodic (storms), seasonal, interannual, and longer (for example, El NiƱo) processes. These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to identify topographic and shallow-water bathymetric features.

Logical_Consistency_Report: All data falls within expected ranges. Completeness_Report: Dataset 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: Survey-grade positions of the survey platforms were achieved with global navigation satellite system (GNSS) receivers and a single GNSS base station. The position of the GNSS base station was derived from two static GNSS occupations on January 14 and January 16, 2014, with durations of 6 and 3 hours, respectively. The static observations were processed using the National Geodetic Survey Online Positioning User Service (OPUS) and averaged to derive the final base station coordinates relative to the North American Datum of 1983 (2011 realization). Post-processing of raw GNSS data was performed with Trimble Business Center and Waypoint Grafnav, for the backpack- and ATV- platforms, respectively. Manufacturer reported accuracy for the differentially corrected horizontal positions for the GNSS rover trajectories is 0.8 cm + 0.5 ppm. Baselines from the GNSS base station varied between 1.5 km and 29 km with a mean of 13 km, suggesting an average horizontal accuracy of about 1.5 cm. Uncertainty in the horizontal positions associated with sinking into the substrate or variable posture during data collection of the surveyors is unknown. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Manufacturer reported accuracy for the differentially corrected vertical positions for the GNSS rover trajectories is 1.5 cm + 1 ppm. Baselines from the GNSS base station varied between 1.5 km and 29 km with a mean of 13 km, suggesting the average vertical accuracy of topographic measurements to be about 3 cm. Uncertainty in the vertical positions associated with sinking into the substrate or variable posture during data collection of the surveyors is unknown. Lineage: Process_Step: Process_Description: Topographic profiles were collected on foot with GNSS receivers mounted on backpacks. Prior to data collection, vertical distances between the GNSS antennas and the ground were measured using a tape measure. Hand-held data collectors were used to log raw data and display navigational information allowing surveyors to navigate survey lines spaced at 50- to 250-m intervals along the beach. Profiles were surveyed from the landward edge of the study area (either the base of a bluff, engineering structure, or just landward of the primary dune) over the beach foreshore, to wading depth on the same series of transects as nearshore bathymetric surveys that were conducted during the same time period. Additional topographic data were collected between survey lines with an all-terrain vehicle (ATV) to constrain the elevations and alongshore extent of major morphological features. Raw GNSS data were logged internally at 2-Hz intervals using a GNSS receiver mounted at a measured height above the ground. Process_Date: 20160325 Process_Step: Process_Description: Positioning data from the survey platforms were post-processed to apply differential corrections from a GNSS base station with known horizontal and vertical coordinates relative to the North American Datum of 1983 (2011 realization). Post-processing of raw GNSS data was performed with Trimble Business Center and Waypoint Grafnav, for the backpack- and ATV- platforms, respectively. Orthometric elevations relative to the NAVD88 vertical datum were computed using National Geodetic Survey Geoid12a offsets. The final point data from the topographic surveyors are projected in cartesian coordinates using the Universal Transverse Mercator (UTM), Zone 10 North, meters coordinate system.
