This dataset contains physical oceanographic data within four fjords in the coastal area of the Gulf of Alaska. Data were collected with a Seabird Electronics conductivity-temperature-depth profiler equipped with external sensors and a water sampler. Glacier runoff provides a link between terrestrial systems and nearshore coastal processes, whereby freshwater input influences the physical oceanographic properties and circulation of fjords (Arimitsu et al. 2016).

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This datasets consist of multiple tables (one for each sample station and frequency), providing echointegration data from forage fish survey transects in Prince William Sound, Alaska. Each file contains analysis exports from EchoView Software Pty Ltd. ver. 7.1.29.30212.

Measurements of conductivity and temperature were collected with a high-accuracy conductivity and temperature recorder (Seabird SBE37 microcat) in approximately 10 m water depth at a single location fronting the village of Wainwright, Alaska, from 24 August to 1 October 2009. The instrument was mounted on the frame approximately 0.50 m off the bottom of the seafloor. Salinity was calculated from conductivity measurements.

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This dataset consists of one table, providing the concentrations of inorganic nutrients (NO2, NO3, PO4, and SiOH4) in water samples collected during summers from multiple depths at sampling stations throughout Prince William Sound, Alaska.

Seaglider is a buoyancy driven autonomous underwater vehicle (AUV) developed by scientists and engineers at the University of Washington's School of Oceanography and Applied Physics Laboratory. Seagliders are designed to glide from the ocean surface to a programmed depth and back while measuring temperature, salinity, depth-averaged current, and other quantities along a sawtooth trajectory through the water. Seaglider has entered wide use in scientific deployments. They are designed for missions in range of several thousand kilometers and durations of many months. Seagliders are commanded remotely and report their measurements in near real time via wireless telemetry.

This dataset contains water conductivity and temperature casts collected by CTD from the research vessel Heron. Voltage profiles were measured by an optical backscatter probe deployed from research vessel Heron. ADCP instrument was deployed 30 m above the seabed, suspended from a fixed vessel (research vessel Strickland). The research vessel Strickland was moored (using 4 anchors) above the central submarine channel downstream of the Squamish delta. File Beamave_EA.txt contains the echo intensity averaged between four ADCP beams in counts. Echo intensity was used to derive the concentration of suspended sediment from 30 m to 60 m water depth, using an acoustic inversion method and physical samples for calibration. File vmag.txt contains the magnitude of velocity in m/s. These data were used to obtain the turbidity current measured on 15th June 2015. Data are in ASCII format.

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 file describes the conductivity, temperature, and depth (CTD) measurements that were collected, and the salinity that was calculated from the conductivity. Data summaries and further details can be found in Erikson and others, 2020.

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This dataset consists of one table, providing the results of surveys conducted to document the summer at-sea distribution and abundance of marine birds and mammals in Prince William Sound, Alaska. Surveys followed standard U.S. Fish and Wildlife protocols for strip surveys. Data include: transect ID, date, time, latitude, longitude, record number, data type, animal species, count, behavior, plumage, distance, observers, observer conditions, the altitude of the survey, ice presence, trip ID, beaufort, transect type, transect width, and comments.

The University of Alaska, Institute of Marine Science is responsible for these data collected aboard the R/V Alpha Helix on cruises HX123, HX124, HX125, and HX126, between May 5, 1989, and June 10, 1989. These data were collected for the Exxon Oil Spill Monitoring Program and the Gulf of Alaska Recirculation (GARS) Project. Funding was provided by the State of Alaska, Sea Grant, and the National Science Foundation. This data was submitted to NODC earlier. This dataset represents a resubmission due to fact that the earlier version had the wrong offsets applied. Field correction for the STD data was derived by comparing single bottle samples to recorded values from the STD sensors. The field correction is based on 15 samples from a total of 16 stations. The field corrections are: 3000 m CTD temperature mean (Nansen-STD) is 0.00536 and 3000 m CTD salinity mean (Nansen-STD) is -0.04131. Data has been processed by NODC to the NODC standard High-Resolution STD/CTD Data (F022) format. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.
