One of the long-recognized gaps in many coastal datasets is water depth directly adjacent to the shoreline. In few places is this more true than in the data-sparse coastal waters of western Alaska. Between the marine depths and onshore elevations lies a critical zone to which traditional ship-based bathymetric surveys do not extend. These areas are best accessed with portable sonar systems attached to small watercraft capable of navigating shallow waters. Nearshore bathymetric data is a vital component to understanding how coastal storms impact landscapes because marine energy is dissipated (wave breaking) and transformed (wave refraction, shoaling) as it moves across this zone in high-energy storm events. Community-scale models of coastal storm impacts, tsunami inundation, and other scenario-based coastal hazard mapping require seamless topographic-bathymetric grids of depths and elevations transitioning from the marine to terrestrial environment. As many communities seek detailed inundation modeling for storm surge preparation and planning purposes, we need to fill gaps in baseline bathymetric data along Alaska's coast. Other uses for nearshore bathymetry include, but are not limited to, expanding our understanding of coastal/inlet dynamics, quantifying alongshore sediment budgets, calibrating bathymetric mapping with remote sensing platforms, monitoring nearshore benthic environments.
An accuracy assessment was conducted on each included dataset for quality assurance purposes. See table 2 in the accompanying report for methods and discussion of the full results.
Horizontal uncertainty varies by community. See table 2 in the accompanying report for methods and discussion of the full results.
