These data include water temperature, salinity, dissolved inorganic carbon (DIC), total alkalinity (TA), dissolved oxygen, and nutrients (nitrate, nitrite, phosphate, silicate, and ammonium). The cruise was funded by the National Oceanic and Atmospheric Administration (NOAA) Arctic Research Program (ARP) and supported by numerous agencies and institutions including the National Science Foundation (NSF). The carbon data were collected at sea and run using equipment from the Ocean Acidification Research Center (OARC) at the University of Alaska Fairbanks (UAF). Jessica Cross was funded by NOAA's Arctic Research Program and Natalie Monacci was funded by the Cooperative Institute for Alaska Research and the Alaska Ocean Observing System. The CTD operations on the cruise were managed by personnel from the Woods Hole Oceanographic Research Institute (WHOI). Dissolved Oxygen and nutrient data were collected by by personnel from the University of Washington Joint Institute for the Study of the Atmosphere (JISAO). Calvin Mordy was funded by the Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI) Program and NOAA's ARP. Phyllis Stabeno is co-Principal Investigator of the EcoFOCI program. The Distributed Biological Observatory (DBO) is envisioned as a "change detection array" along a latitudinal gradient extending from the northern Bering Sea to the Barrow Arc. DBO sampling is focused on transects centered on locations of high productivity, biodiversity and rates of biological change.

Ammonium was measured using an indophenol blue method modified from Mantoura and Woodward (1983).; Replicate information: In a direct comparison of EcoFOCI and BASIS methods, replicate frozen samples from the Bering and Chukchi Sea were analyzed with each method and found to be within 0.5 μM nitrate, 0.04 μM nitrite, and 0.7 μM ammonium (SD, n = 13).; Quality flag convention: All data points are either accepted (retained) or rejected (deleted) during processing, so data are all defined as good.; Method reference: Gordon, I., Jennings, J.C., Ross, J.A., Krest, J. 1993.

NOAA National Centers for Environmental Information custodian carbon dioxide (CO2) gas analyzer carbon dioxide (CO2) gas analyzer measures gaseous carbon dioxide Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.
