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.

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.

Transects of near-surface seawater properties were collected over the fringing reef off Makua, HI, on the north shore of Kauai using a Conductivity-Temperature-Depth (CTD) logger, either hand-carried or mounted to a kayak. The instrument returns temperature, salinity as a function of depth, and latitude/longitude.

These time-series datasets consist of Current Profiler (Teledyne ADCP and WCP, Aanderaa RCM-9) observations, and data from biophysical moorings at 6 locations in Southeast Alaska, near Cross Sound: CS1, CS2, CS3, and CS11 (ADCP and WCP locations); CS11 and CS13 (biophysical locations). Data were collected as part of the GOA IERP lower-trophic-level research effort, and include current speed and direction, calculated current components U and V, temperature, conductivity, salinity, pressure, water depth, oxygen concentration, calculated oxygen percent saturation, turbidity, raw chlorophyll fluorescence and chlorophyll a. Instrumentation included Aanderaa RCM-9 current meter, Teledyne RDI Workhorse Sentinel ADCP (WCP), Teledyne-RDI Long-Ranger 75khz ADCP (LRCP), SeaBird SBE-37 and SBE-30 profilers and WetLabs EcoFluorometers. The cruise was funded by NOAA, Pacific Marine Environmental Laboratory EcoFOCI program and the North Pacific Research Board (NPRB). Instruments were deployed in January, 2013 and recovered at the end of October, 2013 from NOAA Ship Oscar Dyson (DY1301 and DY1309, leg 2, respectively). Deployment and recovery operations on this cruise were managed by EcoFOCI personnel from NOAA/PMEL. Mooring time series data were processed at NOAA/PMEL/EcoFOCI using standard techniques. Time is recorded as UTC. Data contacts: Phyllis Stabeno, Shaun Bell, Ryan McCabe, Peggy Sullivan. Data were taken with participation from National Oceanic and Atmospheric Administration (NOAA), Pacific Marine Environmental Laboratory (PMEL), ; Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI); University of Washington, Cooperative Institute for Climate, Ocean, and Ecosystem Studies (CICOES); North Pacific Research Board (NPRB). Data are in NetCDF.

CTD water column profile and bottom data collected during the 2021-2023 Gulf of Alaska summer bottom trawl surveys conducted by the NOAA Fisheries/Alaska Fisheries Science Center/Resource Assessment and Conservation Engineering Division/Groundfish Assessment Program. Data include temperature, salinity, density, depth, pressure, sound speed, and buoyancy frequency. The data types are digital numeric in a netCDF file.

This dataset contains temperature, salinity, pressure, photosynthetically active radiation (PAR), optical backscatterance (OBS - turbidity), dissolved oxygen, and fluorescence (proxy for chlorophyll-a concentration, an index of primary productivity) profiles, collected from 22 stations that span the length of Glacier Bay proper, from just outside the mouth of the Bay to the heads of both the East and West Arms. Generally mid-channel and equidistant, stations capture a range of depths from shallow sills to deep basins, and are located along the gradient from tidewater glaciers and turbid outwash streams to source waters at Icy Strait. Seven core stations are sampled on nine cruises per year to allow description of intra-annual variation, and all 22 stations are occupied during two of these cruises (July and winter) to allow description of inter-annual variation. This sampling design also allows us to detect long-term seasonal and annual trends, and to describe the current year in a historical context. We measure standard oceanographic parameters throughout the water column: temperature, salinity, pressure, photosynthetically active radiation (PAR), optical backscatterance (OBS turbidity), dissolved oxygen, and fluorescence (proxy for chlorophyll-a concentration, an index of primary productivity). The scope and methods are fully explained in the formal monitoring protocol. The monitoring program was initiated by the U.S. Geological Survey (USGS) in 1993 and jointly operated each year by USGS and Glacier Bay National Park and Preserve through 2008. In 2009, NPS took on full responsibility for the program. That year, the Southeast Alaska Network initiated a comprehensive update of the program, following recommendations from a 2006 program review, peer-reviewed analyses of the Glacier Bay data, and input from staff at USGS, the National Oceanic and Atmospheric Administration, and several universities. The update resulted in retention of most stations, the addition of one new station, and a temporal shift of the sampling effort away from a quarterly cruise schedule. SEAN also rebuilt the data processing and management system to meet NPS I&M standards and to ensure that all products -from raw and validated field data through the protocol and synthesis reports - are fully validated and web accessible at https://irma.nps.gov/DataStore/Reference/Profile/2168864. Data are in CSV format.
