Bering Strait Mooring Data 2022-2023

Bering Strait Moorings 2022-2023 This is an archive of data from moorings deployed in Bering Strait from summer 2022 and to summer 2023. Mooring deployments were funded by the NSF-Arctic Observing Network award PLR-2153942 (PIs: Woodgate and Peralta-Ferriz). The mooring work required 2 dedicated cruises: - in 2022 (8th-19th September), a ~ 12 day cruise on the US vessel Norseman2 deployed the moorings. Some CTD (conductivity, temperature, depth) sections were run on this cruise, and those data are archived separately. - in 2023 (4th-14th July), a ~ 11 day cruise on the US vessel Norseman2 recovered the moorings. Some CTD sections were run on this cruise, and those data are archived separately. In 2022, a total of three moorings were deployed: - two moorings (A2 and A4) in the US channel of the strait, - one mooring (A3) at a site just north of the strait. In what follows, mooring names include a two digit suffix to represent year of deployment. In 2023, all three moorings were successfully recovered. Sites A2, and A3 were established in 1990. A2 and A3 have been occupied almost continuously (all years except 96-97) since then. Site A4 was established in 2001. Mooring location A2 is in the middle of the eastern (Alaskan side) channel. Mooring location A3 is just north of the strait, immediately east of the Russian-US EEZ (Exclusive Economic Zone) line. Experience has shown that site A3 samples both eastern and western channel water. Mooring location A4 is close to the Alaskan coast and allows measurement of the Alaskan Coastal Current.
