Single-beam bathymetry data near Kotlik, Alaska, collected July 2021
Description
DGGS Raw Data File 2021-14, Single-beam bathymetry data near Kotlik, Alaska, collected July 2021, presents bathymetric data for the purpose of assessing 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 Kotlik on July 7 and 9, 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. This data collection is being released as a Raw Data File with an open end-user license. All files are available from the DGGS website: http://doi.org/10.14509/30764.
