  • This dataset includes bathymetric sounding points for the near-shore regions of the Chukchi Sea and Elson Lagoon (Beaufort Sea) for the Barrow region of northern Alaska, along with a bathymetric surface interpolated from these sounding points. Bathymetric surveying was conducted during July and August of 2015 with high-resolution dGPS and single beam sonar. Surveys were conducted on an inflatable Achilles boat with the dGPS antenna and echo sounder placed (on the same pole) off to one side of the boat. dGPS and sonar data were logged on different platforms that were then time-synced later. Sounding points follow the path of the survey boat. At any one sounding point; water depth, bottom elevation, bottom ellipsoid height among other fields are given. Sounding point depths were corrected for salinity and temperature. The average horizontal precision for any one sounding point is 2.3 cm. The average vertical precision for any one sounding point is 4.6 cm (dGPS uncertainty) plus 0.1% of depth (sonar manufacturers stated accuracy). The 10m resolution interpolated surface was created with the Topo to Raster tool within the 3D Analyst license for ArcGIS for Desktop. Pixel values reflect water depth in meters. Related datasets include: recent digital shorelines from dGPS survey, long-term shorelines digitized from imagery and results of coastal change analysis (annual and long-term rates of erosion or accretion). This bathymetric data may be of interest to land managers, scientist and engineers for modeling storm surge effects and coastal erosion. This dataset was collected as part of the Barrow Area Information Database (BAID, https://barrowmapped.org) and was originally made available on the BAID project website.
