This dataset contains the discrete bottle (CTD profile) data of the only cruise that took place in the US Arctic during the 2020 COVID-19 related field work shutdown. The cruise took place from October 15, 2020 to November 19, 2020 aboard the R/V Sikuliaq, departing from and returning to Seward, AK. 148 casts were occupied in the Bering and Chukchi Seas around Alaska. At all stations, CTD casts were conducted, and discrete water samples were collected in Niskin bottles. The cruise was part of the project entitled “Monitoring the Western Arctic Boundary Current in a Warming Climate: Atmospheric Forcing and Oceanographic Response”, funded by the National Science Foundation as part of the Arctic Observing Network (AON) to Robert Pickart at WHOI. A number of ancillary projects were also carried out taking advantage of a ship of opportunity during the COVID-19 shutdown. The marine carbonate data to investigate ocean acidification were collected as an ancillary project to visit the Distributed Biological Observatory (DBO), funded by the NOAA Arctic Research Program to Jessica Cross at NOAA PMEL and Natalie Monacci at UAF.

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.
