Water temperature, salinity, velocity, including ADCP ice tracking, collected from Bering Strait Moorings A2, A3, A4 in Bering Strait from 2019-09-07 to 2021-07-09 (NCEI Accession 0253624)

This is an archive of data from moorings deployed in Bering Strait from summer 2019 and summer 2020 to summer 2021. Mooring deployments were funded by the NSF-Arctic Observing Network award PLR-1758565 (PIs: Woodgate and Peralta-Ferriz). The mooring work required 3 dedicated cruises: - in 2019 (5th - 15th September), a ~ 11 day cruise on the US vessel Norseman2 deployed the 2019 moorings. Some CTD sections were run on this cruise, and those data are archived separately. - in 2020 (1st - 18th September), a ~ 19 day cruise on the US vessel Norseman2 deployed the 2020 moorings. Some CTD sections were run on this cruise, and those data are archived separately. - in 2021 (7th - 17th July), a ~ 11 day cruise on the US vessel Norseman2 recovered all the moorings. Some CTD sections were run on this cruise, and those data are archived separately. In both 2019 and 2020, a total of three moorings were deployed (each year): - 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. Although the 2019 moorings would normally have been recovered in 2020, the global COVID-19 pandemic prevented this. Instead, the 2020 cruise only deployed a further 3 new moorings (each ~ 400m west of their usual positions). All 6 moorings were recovered in 2021. 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.
