This dataset contains discrete bottle-sample data from CTD casts collected for a NOAA, PMEL, EcoFOCI Fall mooring research cruise on board NOAA Ship Oscar Dyson (DY1708). The cruise spanned September 22 - October 7, 2017. CTD data collection occurred September 23 through October 4, 2017. These data are a companion set to CTD profile data from the same cruise (NCEI Accession 0211794, DOI https://doi.org/10.25921/gez4-yh74). CTD and sample locations include a subset of the established 70-meter isobath line stations between PMEL/EcoFOCI moorings M2 (56.87 N,164.05 W) and M8 (62.20 N,174.67 W), the defined "Unimak Box" at Unimak Island in the Aleutian Islands, and casts at other mooring stations including NOAA, National Marine Mammal Lab moorings and within the defined Distributed Biological Observatory (DBO-1). See NOAA DBO site for further information on DBO sampling areas, and NOAA EcoFOCI site for information on established CTD lines. Chlorophyll data were processed by NOAA, Alaska Fisheries Science Center (AFSC) using standard techniques. Nutrient data were processed at NOAA, PMEL (C.Mordy) and include nitrate, nitrite, phosphorus, silicate, and ammonium. Nutrient and chlorophyll data contacts: Calvin Mordy, Phyllis Stabeno, Colleet Harpold, Peggy Sullivan, Shaun Bell.

CTD profile data (109 casts) were collected in the northeast Bering Sea and Chukchi Sea from the Fishing Vessel Bristol Explorer (cruise BE1201) during a pelagic fish survey (Arctic EIS), August 6 to September 27, 2019. CTD casts occurred along a previously-defined trawl survey station grid with stations ~30nm apart. Northern Bering Sea stations were between 60°N and Bering Strait; Chukchi stations sat between the Bering Strait and 72.5°N. Profile data and water samples were collected by NOAA, AFSC as a part of the Ecosystems & Fisheries-Oceanography Coordinated Investigations (EcoFOCI) program in collaboration with Pacific Marine Environmental Laboratory (PMEL). Profile variables include dual temperatures (°C), dual salinity, chlorophyll fluorescence(ugrams/l), oxygen concentration (umol/kg), transmission (percent), and calculated values Sigma-T (kg m-3) and oxygen percent saturation (percent). This data set contains 1-meter-averaged water-column profile data. Profile data from CTD instruments were processed at NOAA/PMEL/EcoFOCI using standard techniques. Null values are represented as 1.00E+35. CTD data contacts: Phyllis Stabeno, Calvin Mordy, Peggy Sullivan, Shaun Bell.

This is an archive of CTD data from the 2024 Bering Strait mooring cruise. The cruise was funded by the NSF-Arctic Observing Network grants: - PLR-2153942 (PIs: Woodgate and Peralta-Ferriz). The data are from a ~ 11 day cruise - on the US vessel Norseman II - from 8th-18th July 2024 - sailing from and to Nome, Alaska, USA - to the Bering Strait and southern Chukchi Sea The cruise was also to service oceanographic moorings in the strait and those data are archived separately. This is an archive of both hydrographic and bottle data. A total of 154 casts were taken and are included in this archive. Water samples were taken for salinity (6) and nutrients (195) from the CTD rosette. Nutrient data are included in this archive. Salinity samples were only to confirm sensor/bottle discrepancies and are not included in this archive. A separate pumping system was used to take trace metal (and accompanying nutrient) samples during this cruise (lead: Laramie Jensen). These data are archived separately. Stations were taken in US waters near mooring locations and on sections in the Bering Strait and southern Chukchi Sea. See cruise report, accompanying event log and data headers for map, station locations, calibration, and processing details. The data are taken using an SBE9-11plus system, recording - pressure - temperature (dual system) - conductivity (dual system) - oxygen (dual system) - fluorescence - turbidity connected also to an - SUNA nitrate sensor, recording both internally and with the CTD data. Bottle samples returned to the University of Washington (UW) for analysis post cruise.

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, temperature, salinity and nutrients during USCGC Healy cruise HLY0902 (EXPOCODE 33HQ20090403) in the Bering Sea from 2009-04-03 to 2009-05-12. The cruise was funded by the National Science Foundation (NSF) for the Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program (BEST-BSIERP) and supported by numerous agencies and institutions. The CTD operations on the cruise were managed by personnel from NOAA/PMEL in the Eco FOCI program, with technical expertise from Scripps Institution of Oceanography personnel, and deployment assistance from Healy personnel.

This dataset contains water temperature, salinity, and others taken by CTD, as well as water column chlorophyll, nutrients, and others from Niskin bottle samples collected in the Chukchi Sea during the 2015-08-12 to 2015-09-03 and the 2017-08-06 to 2017-08-22 Arctic Marine Biodiversity Observing Network (AMBON) research cruises aboard the research vessel Norseman II. This dataset consists of two comma-separated values (csv) files (naming convention 'AMBON [YYYY] bottle file new_NutrientChlaDelO18.csv) containing measurements of water samples collected by a Niskin bottle array on a Seabird SBE55 CTD at hydrographic stations in each 2015 and 2017. These data files contain chemistry measurements made on bottle samples, including Chlorophyll a Concentration (micro-g/L), and nutrient concentrations [micro-mol/L] (Ammonia, Phosphate, Nitrite+Nitrate, and Silicate). Water samples were also collected for analysis of 18O/16O ratios. The data files also include physical information, depth, salinity and temperature measurements from the CTD at the location of bottle sample collection. Two source CTD ASCII data files (named AMBON[YYYY]_bottles.all) consisting of measurements from the depths at which the Niskin bottles were tripped are also included in this dataset. The data provides information on important Arctic Chukchi Sea ecosystem parameters, including temperature, salinity, pressure, and fluorescence as an index of phytoplankton biomass. Data are in text and CSV formats.

The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and U.S. partners. It has produced a merged internally consistent dataset of open ocean subsurface measurements for biogeochemical investigations, in particular, studies involving the carbon system. The original focus area was the North Atlantic Ocean, but over time the geographic extent expanded and CARINA now includes data from the entire Atlantic, the Arctic Ocean, and the Southern Ocean. The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.
