Oceanographic temperature, salinity and oxygen profiles and other measurements from CTD casts by the National Park Service (NPS) and United States Geological Survey (USGS) for the Inventory and Monitoring Program of the Southeast Alaska Network (SEAN) from multiple platforms in Glacier Bay, Alaska from 1993-07-01 to 2021-10-05 (NCEI Accession 0074611)

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.
Temperature, salinity and other variables collected from discrete sample and profile observations using CTD, bottle and other instruments from THOMAS WASHINGTON in the Gulf of Alaska and North Pacific Ocean from 1984-05-04 to 1984-06-04 (NCEI Accession 0143390)

This dataset includes discrete sample and profile data collected from THOMAS WASHINGTON in the Gulf of Alaska and North Pacific Ocean from 1984-05-04 to 1984-06-04 and retrieved during cruise P16_1984a. These data include BAROMETRIC PRESSURE, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, SALINITY, Tritium (Hydrogen isotope), WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include CTD and bottle. These data were collected by Roland A. de Szoeke of Oregon State CEOAS (OSU-CEOAS) and Lynne D. Talley of University of Rhode Island; Graduate School of Oceanography (GSO) as part of the P16N_31WT19840504 dataset.
Glacier Bay oceanography processed CNV data files (OC C) for cruise year 2023
공공데이터포털
"CNV" files are made by converting the sensor levels in HEX files into useful engineering units, which are further corrected for detector sensitivities and then binned at 1-meter intervals. The files contain straight ASCII data, useable with many software products including spreadsheets. Each file contains a preamble of detailed documentation including collection and processing dates, processing steps taken, intermediate files used, adjustment parameters considered, sensors employed for the cast, and the order data are placed in columns. All deliverables under this reference have passed quality control processing specified in the protocol active at the time of processing. All deliverables have been "accepted" for dissemination by the principal investigator or a delegate. These data have NOT undergone final grading. See deliverable OC_D for final graded data to be used for analyses.
