Surface ocean dissolved oxygen isotope data (d17O, d18O, 17D) collected in the Chukchi, Beaufort, Canada Basin, and Makarov Basin in 2022 during the Synoptic Arctic Survey (HLY2202)

These data files contain surface dissolved O2 triple isotope (d170, d18O, 17D) and dissolved O2/Ar saturation ratio collected on the 2022 US Synoptic Arctic Survey Cruise in September and October 2022. The data are useful for understanding the balance of physical and biological controls driving surface ocean dissolved O2 concentrations and for calculating net biological community production rates. The data were collected with funding from NSF (National Science Foundation) Award 2053116 “Collaborative Research: Taking the Pulse of the Arctic Ocean - A US Contribution to the International Synoptic Arctic Survey” Data were collected between September 3rd 2022 and October 25th, 2022 from the surface science seawater supply of USCGC (United States Coast Guard Cutter) Healy on Cruise ID HLY2202. The cruise departed from Dutch Harbor, AK (Alaska) and disembarked in Dutch Harbor, AK and sampled waters of the Bering and Chukchi Seas, the Canada Basin up to the North Pole, and then a return path through the Makarov Basin before sampling the Chukchi Shelf again and returning to port.
