This dataset contains water temperature, conductivity, and others taken by CTD and Niskin bottles in the Chukchi Sea during the 10 August - 3 September 2015 Arctic Marine Biodiversity Observing Network (AMBON) research cruise. The data provides information on important Arctic Chukchi Sea ecosystem parameters, including temperature, salinity, pressure, and fluorescence as an index of phytoplankton biomass. In aggregate these variables are basic descriptors of the water masses entering the Chukchi Sea from the Pacific through Bering Strait. The compiled directory consists of three files. - AMBON2015_CTDprofiles.ascii (also in csv and netcdf) - AMBON2015.hdr - AMBON2015_ctdBottleData_L2_v1.csv The first file is an ASCII file consisting of Seabird SBE55 CTD measurements from the depths at which the Niskin bottles were tripped; the file is intended to complement the file named 'AMBON 2015 bottle file new- Nutrients_chlorophyll bottle file.csv' in the Arctic Marine Biodiversity Observing Network (AMBON): Water column and benthic processes project (Cooper and Grebmeier). The second file is a ASCII file consisting of Seabird SBE55 Conductivity, Temperature, Depth (CTD) header information (named AMBON2015.hdr); the file accompanies the main CTD data file. The dataset describes each CTD cast number, location, bottom depth and other ancillary information. The third file is a ASCII file consisting of Seabird SBE55 Conductivity, Temperature, Depth (CTD) downcast data (AMBON2015_ctdBottleData_L2_v1.csv). Data were post calibrated and adjusted to bottled samples. Data are in ASCII, CSV, and NetCDF.

This CTD data set, consisting of 70 casts, was collected in the Chukchi Sea ice cruise mb11-01 from the fishing vessel Mystery Bay (August 15 - September 10, 2011). The cruise was funded by DOI Bureau of Ocean Energy Management (BOEM) through the NOAA National Marine Mammal Laboratory. CTD operations on this cruise were managed by Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI) personnel from NOAA/PMEL as part of the Department of Interior (DOI)/BOEM Arctic Whale Ecology Study (ARCWEST) and Chukchi Sea Acoustics, Oceanography, and Zooplankton (CHAOZ) programs. Profile data from CTD instruments were processed at NOAA/PMEL/EcoFOCI using standard techniques. Data from bottle samples include phosphate, silicate, nitrate, nitrite, ammonium, and chlorophyll. Chlorophyll data are submitted separately through NOAA/AFSC. Data are on a 1-meter vertical grid and combine both averaged CTD profile data and bottle samples, where missing data are listed as 1e+35. CTD data contact: Phyllis Stabeno, Peggy Sullivan. Nutrient and bottle data contact: Calvin Mordy. Chlorophyll data contact: Jeffrey M. Napp. Data are in CSV format.

This dataset contains water temperature, salinity, oxygen, currents and other data taken by CTD, Niskin bottles, and ADCP from the research vessel Keifu Maru, cruise KS15-06, in the North Pacific Ocean. The entire cruise was carried out during the period from June to August, 2015. Hydrographic observation was made using a Sea-Bird Electronics (SBE) 36 position carousel equipped with 10-liter Niskin water sample bottles, a CTD system (SBE911plus) equipped with JFE Advantech oxygen sensor (RINKO III) along 165E. Water samples were analyzed for salinity, dissolved oxygen, nutrients, pH and phytopigment (chlorophyll-a and phaeopigments). Current data was measured by Teledyne RDI's vessel-mounted ADCP system (38kHz Ocean Surveyor). This dataset is U.S. State Department MSR U2014-036 as part of the World Data Service for Oceanography.
