Time-series measurements of waves, currents, water levels, sea surface temperatures, ocean salinity, and water, air, and ground temperatures were collected in July through September 2011 in and around Arey Lagoon, near Barter Island, Alaska. Directional wave spectra, currents, water levels, salinity, and bottom and surface water temperatures were measured with a bottom-mounted 1MHz Nortek AWAC, HOBO temperature loggers, and a Solinst Levelogger in ~5m water depth offshore of Arey Island. Within Arey Lagoon, a bottom-mounted frame equipped with a Nortek 1MHz Aquadopp, Solinst Levelogger, and HOBO temperature loggers measured currents, water levels, and water temperatures. Ground temperatures (maximum depth 3 meters...

This dataset contains information on the probabilities of storm-induced erosion (collision, inundation and overwash) for each 100-meter (m) section of the United States Pacific coast for return period storm scenarios. The analysis is based on a storm-impact scaling model that uses observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast will respond to the hydrodynamic forcing. Storm-induced water levels, due to both surge and waves, are compared to coastal elevations to determine the probabilities of three types of coastal change: collision (dune erosion), overwash, and inundation. Data on morphology (dune crest and toe elevation) and hydrodynamics (storm surge,...

This data release provides flooding extent polygons based on sea-level rise and wave-driven total water levels for the coast of American Samoa's most populated islands of Tutuila, Ofu-Olosega, and Tau. Oceanographic, coastal engineering, ecologic, and geospatial data and tools were combined to evaluate the increased risks of storm-induced coastal flooding due to climate change and sea-level rise. We followed risk-based valuation approaches to map flooding due to waves and storm surge at 10-m2 resolution along these islands coastlines for annual (1-year), 20-year, and 100-year return-interval storm events and +0.25 m, +0.50 m, +1.00 m, +1.50 m, +2.00 m, and +3.00 m sea-level rise scenarios.

This data release provides flooding extent polygons and flood depth rasters (geotiffs) based on sea-level rise and wave-driven total water levels for the coast of the most populated Hawaiian, Mariana, and American Samoan Islands. Oceanographic, coastal engineering, ecologic, and geospatial data and tools were combined to evaluate the increased risks of storm-induced coastal flooding due to climate change and sea-level rise. We followed risk-based valuation approaches to map flooding due to waves and storm surge at 10 square meter resolution along these islands’ coastlines for annual (1-year), 20-year, and 100-year return-interval storm events and +0.25 m, +0.50 m, +1.00 m, +1.50 m, +2.00 m, and +3.00 m sea-level...

Simulatations of water levels in the Salish Sea for a continuous hindcast of the period October 1, 1985, to September 30, 2015 were conducted to evaluate the utility and skill of a sea-level anomaly predictor and to develop extreme water level estimates accounting for decadal climate variability. The model accounts for sea level position, tides, remote sea-level anomalies, local winds and storm surge and stream flows as they affect water density. Comparison of modeled and measured water levels showed the model predicts extreme water levels at NOAA tide gage stations within 0.15 m. Model inputs and outputs of time-series water levels along the -5 m depth isobath are presented. In addition, extreme water level recurrence...

Single-beam bathymetry data were collected in 2010 and 2011 in the nearshore waters around Barter Island, Arey Island, and within Arey Lagoon, Alaska. Measurements were made from a small boat or dinghy using one of three systems: a Humminbird 898 SI Fish Finder with integrated GPS (2010 and 2011), an Ohmex Sonarmite BT integrated with a Trimble GeoHX series GPS (2011), or a Garmin Sounder with integrated GPS (2011). Each system collected single-beam water depth with accuracies better than 4 meters (m) horizontal and 25 centimeters (cm) vertical.

This portion of the data release presents a wave model application developed to simulate wind generated surface gravity waves on an ancient lake on Mars. The phase-averaged wave model, SWAN, was applied within the Delft3D modeling system (Deltares, 2018) with reduced gravity and a range of atmospheric densities and wind speeds to simulate potential conditions that could generate wind waves on Mars. The data release includes model input files for simulations with three different atmospheric densities, compatible with version 4.04.01 of the Delft3D modeling system.
Beach elevation profiles were measured along 29 shore-normal transects on and around Arey and Barter Islands, Alaska in August 2010 and July 2011. Profile data are available in a single comma-delimited file and a zip file including multiple .jpg images that show a visual representation of the individual profiles.

Simulations of water levels in the Salish Sea over the period October 1, 2016 to September 30, 2020 were conducted to validate the Salish Sea hydrodynamic model. The model accounts for sea level position, tides, remote sea-level anomalies, local winds and storm surge and stream flows as they affect water density. Comparison of modeled and measured water levels showed the model predicts extreme water levels at NOAA and USGS tide gage stations within 0.15 m. Model inputs and outputs of time-series forcing and water levels, respectively, are presented.

Sediment grab samples were collected on the barriers and nearby seabed on and around Arey and Barter Islands, Alaska in July 2011 and analyzed for mean grain size. 43 terrestrial grab samples were collected along 14 shore-normal beach transects (12 on Arey Island and 2 on the western spit of Barter Island) at the seaward water line, the berm crest or top of the island, and at the lagoon water line. 11 seabed samples were collected using a small pipe dredge deployed from a small boat; 2 in the vicinity of deployed oceanographic instruments, 8 on the ocean side of Arey Island, and 1 in Arey Lagoon. Two of the grab samples were sieved and analyzed for grain size distributions. Mean grain size of remaining samples was...

Estimated start date, end date, and duration of open water at a location fronting Barter Island, Alaska derived from projected sea ice extents in 4 global climate models: MIROC5, BCC-CSM1.1, INM-CM4, and GFDL-ESM2M. Starting and ending dates are when sea ice retreated or is projected to retreat offshore by more than 80 kilometers fronting Barter Island. Projected coastal storm events were derived by downscaling atmospheric conditions of the RCP 4.5 climate scenario with the MIROC5 global climate model (GCM). Sea ice retreat distances were estimated from 4 separate GCMs: MIROC5, BCC-CSM1.1, INM-CM4, GFDL-CM3.
