Discrete samples were collected on research cruise ID NRS2022 (-01T, -01S, -02S) between July 12, 2022 and September 5, 2022, and analyzed for oxygen/argon ratios and triple oxygen isotopes. Samples were collected intermittently from the underway seawater supply throughout the cruise, which departed from Homer, Alaska (AK) and sampled waters of the Bering, Chukchi, and Beaufort Seas, ending in Nome, AK. Samples were also collected at various depths from a selection of conductivity, temperature, and depth (CTD) casts during the second leg of the cruise (NRS2022_02S). The measurements here contribute to characterizing both the chemical environment and the rates of net and gross biological oxygen production in the Pacific-influenced Arctic.

Underway O2/Ar (Oxygen/Argon) and oxygen data collected on a research cruise on the vessel Norseman II, Bering, Chukchi, and Beaufort Seas, Arctic Ocean, July-September 2022
Data were collected between July 13, 2022 and September 5, 2022 using an equilibrated inlet mass spectrometer (EIMS, Cassar et al., 2009) connected to the surface seawater supply of Norseman II on Cruise ID NRS2022 (01T, 01S, 02S). Data were collected near-continuously over the cruise track which departed from Homer, Alaska (AK) and sampled waters of the Bering, Chukchi and Beaufort seas, ending in Nome, AK. The measurements here contribute to characterizing both the chemical environment and the rate of net biological oxygen production.

These data files contain surface dissolved O2 (Oxygen) concentration and dissolved O2/Ar (Oxygen/Argon) saturation ratio for the Bering and Chukchi Seas with relevant accompanying ancillary information. 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 1928684 “High Resolution Observing of Arctic Net Community Productivity with Ships of Opportunity” Data were collected between May 21st, 2021 and June 13th, 2021 from the surface uncontaminated seawater supply of R/V (Research Vessel) Sikuliaq on Cruise ID (Identifier) SKQ202014S. Data were collected near-continuously using an equilibrated inlet mass spectrometer (EIMS) and an Aanderaa optode, with occasional outages for instrument maintenance or flow disruptions. The cruise departed from Dutch Harbor, AK (Alaska) and disembarked in Seward, AK and sampled waters of the Bering and Chukchi Seas.more » « less

Data were collected between August 1, 2019 and August 24, 2019 using an equilibrated inlet mass spectrometer (EIMS, Cassar et al. 2009) connected to the surface uncontaminated seawater supply (which had a nominal intake depth of 3.5 meters) of Ocean Starr on leg 1 of Cruise identifier (ID) OS1901. Data were collected near-continuously over the cruise track which departed from Dutch Harbor, Alaska (AK) and sampled waters of the Bering and Chukchi Sea, ending in Nome, AK. This was a part of the Arctic Integrated Ecosystem Survey (Arctic IES) program. The objective of Arctic IES is to understand how reductions in Arctic sea ice and the associated changes in the physical environment influence the flow of energy through the ecosystems of the Chukchi and Beaufort seas. Two research expeditions in the Beaufort and Chukchi seas during late summer and early fall 2017 and 2019 were designed to address this objective. This survey takes measurements of the: 1) physical environment (temperature, salinity, nutrients); 2) seasonal composition, distribution and production of phytoplankton (plants); 3) distribution and standing stocks of zooplankton (bird, whale, and fish food); 4) assemblages, distributions, abundances, size, diet, and fitness of larval, early juvenile, and adult fishes; and 5) distribution and relative abundances of seabirds and marine mammals. The measurements here contribute to characterizing both the chemical environment and the rate of net biological oxygen production.more » « less

Data were collected on Cruise identifier (ID) OS1901_L1 between August 1, 2019 and August 24, 2019 from either the surface uncontaminated seawater supply of research vessel (R/V) Ocean Starr or from Niskin-style water sample bottles attached to a conductivity-temperature-depth package maintained by the National Oceanic and Atmospheric Administration (NOAA) Pacific Marine Environmental Laboratory. Data were collected periodically over the cruise track which departed from Dutch Harbor, Alaska (AK) and sampled waters of the Bering and Chukchi Sea, ending in Nome, AK. This was a part of the Arctic Integrated Ecosystem Survey (Arctic IES) program.

These data files contain surface dissolved O2 (Oxygen) concentration and dissolved O2/N2 (Oxygen/Nitrogen) saturation ratio for the Bering, Chukchi, and Beaufort Seas with relevant accompanying ancillary information. 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 1928684 “High Resolution Observing of Arctic Net Community Productivity with Ships of Opportunity” Data were collected between October 17th, 2020 and November 16th, 2020 from the surface underway seawater supply of R/V (Research Vessel) Sikuliaq on Cruise ID (Identifier) SKQ202014S. Data were collected near-continuously using Pro-Oceanus miniTDGP (total dissolved gas pressure instrument), a SBE45 thermosalinograph, and a SBE43 dissolved O2 sensor, with occasional outages for instrument maintenance or flow disruptions. The cruise departed and returned from Seward, AK (Alaska) and sampled waters of the Bering, Chukchi and southern Beaufort Seas.more » « less
