Single-beam bathymetry data near Napakiak, Alaska, collected June 2021

DGGS Raw Data File 2021-15, Single-beam bathymetry data near Napakiak, Alaska, collected June 2021, presents bathymetric data to assess coastal hazards and for river migration studies. The State of Alaska Division of Geological & Geophysical Surveys (DGGS) used a M2Ocean Hydroball-an integrated echosounder, Global Navigation Satellite System (GNSS) antenna, and inclinometer-to collect bathymetric transects near Napakiak on June 29-30, 2021. Bathymetric data were corrected using a coincident water level time series referenced to a vertical datum using GNSS survey. The bathymetric data were processed using CIDCO DepthStar.
