Dissolved inorganic carbon (DIC), total alkalinity (TA) and other parameters collected from discrete sample and profile observations during the USCGC Healy cruise HLY1801 (EXPOCODE 33HQ20180807) in the Bering Sea, Chukchi Sea and Beaufort Sea along transect lines in the Distributed Biological Observatory (DBO) from 2018-08-07 to 2018-08-24 (NCEI Accession 0221911)

This dataset includes chemical data from discrete samples and physical data from a profiling CTD collected during the USCGC Healy cruise HLY1801 (EXPOCODE 33HQ20180807) in the Bering Sea, Chukchi Sea and Beaufort Sea along transect lines in the Distributed Biological Observatory (DBO) from 2018-08-07 to 2018-08-24. Data was collected along transect lines in the Distributed Biological Observatory (DBO) areas DB01, 03, 04, and 05. These data include water temperature, CTD salinity, dissolved inorganic carbon (DIC), total alkalinity (TA), CTD 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 from the Niskin Bottles and run using equipment from the Ocean Acidification Research Center (OARC) at the University of Alaska Fairbanks (UAF). The measurements of carbon-related parameters were funded by NOAA's Arctic Research Program and 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). Nutrient data were analyzed by the researchers from University of Washington Joint Institute for the Study of the Atmosphere (JISAO) and 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.
