Ohman 2020 data release DOI:10.5066/P9LGYO2Q Pacific Coastal and Marine Science Center, Santa Cruz, CA U.S. Geological Survey https://doi.org/10.5066/P9LGYO2Q 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 below the surface), were measured with HOBO temperature loggers and EMS iButtons at incremental depths across a tundra bluff, within a wet sedge region, and on the Arey Island island surrounding Arey Lagoon. This metadata describes the current-velocity data that were collected. Data summaries and further details can be found in Erikson and others, 2020. Data were obtained to provide inputs and validation data for a numerical model, and additionally to provide baseline environmental data previously not available.

Li H. Erikson Ann E. Gibbs Bruce M. Richmond Curt D. Storlazzi Benjamin M. Jones Karin A. Ohman 2020 Erikson, L.H., Gibbs, A.E., Richmond, B.M., Storlazzi, C.D., Jones, B.M., and Ohman, K.A., 2020, Changing storm conditions in response to projected 21st century climate change and the potential impact on an arctic barrier island–lagoon system—A pilot study for Arey Island and Lagoon, eastern Arctic Alaska: U.S. Geological Survey Open-File report 2020-1142 https://doi.org/10.3133/ofr20201142 Standard operating procedures were used to collect all data. Instruments used to measure salinity, waves, water levels, and currents were calibrated prior to deployment. Directional wave and current data were calibrated to account for the magnetic declination (23.3 degrees) so that all reported values are relative to true north. Manufacturer instrument resolution and accuracy are as follows: AWAC waves: within 2 degrees for directions, <1% error of measured wave heights and periods; AWAC velocities: ~1% accuracy of measured values; AWAC and Aquadopp pressures: within 0.5%; AWAC and Aquadopp nearbed water temperatures: within 0.1 degrees Celsius; Aquadopp velocities: accuracy of 2cm/s; Solinst level logger conductivity: accuracy within 0.1% of measured values; HOBO temperature loggers: accuracy within 0.2 degrees Celsius; Solinst Levelogger temperatures: within 0.1 degrees Celsius; EMS iButton temperature loggers: accuracy of 1 degree Celsius. Data have been checked for duplications and omissions. Missing data have been filled with NaN values. Where data were not collected a value of n/a is used. Near bed salinity concentration data measured in August 2011 with the Solinst Leveloggers that were mounted on the AWAC and Aquadopp instrument frames are questionable. Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. Marine point locations were measured with a hand-held, WAAS enabled Garmin 76CSx GPS unit. Horizontal accuracy is estimated to be 5 meters. Binned velocity measurements were obtained offshore of Arey Barrier Island near Kaktovik, Alaska with a Nortek 1MHz AWAC in approximately 4.7m water depth. 20-minute averages were reported every 20 minutes. Bin heights above the seabed were 2.40, 3.40, 4.40 meters. Binned velocity measurements were obtained in Arey Lagoon near Kaktovik, Alaska with a Nortek 1MHz Aquadopp in approximately 1.15 m water depth. 10-minute averages were reported every 30 minutes. Bin height above the seabed was 1.01 meters. Data were post-processed using Nortek Aquapro, Quickwave, and AWAC-AST software. 20111020 Performed minor edits to the metadata to correct typos.
