Underway O2/Ar (Oxygen/Argon) and oxygen data collected on a research cruise on the vessel Ocean Starr, Bering, Chukchi, and Beaufort Seas, Arctic Ocean, 2019.

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.

Description
Summary: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.
