Single-beam bathymetric data near Chefornak, Alaska, collected August 17, 2022
Description
Single-beam bathymetric data near Chefornak, Alaska, collected August 17, 2022, Raw Data File 2023-11, provides bathymetric data collected near Chefornak, Alaska, on August 17, 2022. The purpose of this survey is to provide bathymetric data for the assessment of coastal hazards and riverine erosion studies. These data were collected using an M2Ocean Hydroball integrated bathymetric sensor and processed using CIDCO DepthStar software. Coincident Global Navigation Satellite System (GNSS) base station and water level time series data were collected using Trimble survey equipment and a Solinst Levelogger pressure and temperature sensor, respectively, to correct horizontal and vertical positions. This data product does not meet the International Hydrographic Organization (IHO) bathymetric coverage standard (IHO, 2022), is not intended for use in determining navigability, and is released as a Raw Data File with an open end-user license. The data are available from the DGGS website: http://doi.org/10.14509/31009.
