Description:

Abstract:

The required grid and bathymetry files to run a nested spectral wave model (Simulating Waves WAves Nearshore [SWAN]; Booij and others, 1999) for the central Beaufort Sea coast of Alaska are provided. A three-level SWAN nesting grid with grid resolutions of 5000 meters, 1000 meters, and 200 meters for the overall, intermediate and detail grids, respectively (see included Browse Graphic) has been developed. For this purpose, available local bathymetry (Coastal Frontiers Corporation, 2014; Kasper and others, 2019) was merged with a larger-scale product (IBCAO Version 4.0 Compilation Group, 2020). Further details about the development of this model, model forcings and model settings can be found in Nederhoff and others (2021).

Purpose:

The purpose of this data release is to provide researchers, engineers, and other potential users with grids and bathymetry that can be used to run the SWAN wave model for the central Beaufort Sea coast of Alaska. These grids and bathymetries were developed through collaborative work between the U.S. Geological Survey (USGS) and Deltares USA. Financial support was provided by the USGS Coastal Marine Hazards and Resources Program and U.S. Bureau of Ocean Energy Management through Interagency Agreement M17PG00046 for the project titled: ‘Wave and Hydrodynamic Modelling Within the Nearshore Beaufort Sea.’ This data release does not intend to provide comprehensive oceanic input data from outside sources, nor does the use of those products imply endorsement by the U.S. Government.

Supplemental_Information:

Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
