Water temperature, conductivity, and others taken by CTD and Niskin bottles from the research vessel Norseman II Data for Arctic Marine Biodiversity Observing Network, AMBON, Program in the Chukchi Sea from 2015-08-10 to 2015-09-03 (NCEI Accession 0229073)

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 compliment 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 Grebmier).

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.
