This is an archive of data from moorings deployed in Bering Strait from 2021-07-10 to 2022-09-11. Mooring deployments were funded by the NSF-Arctic Observing Network award PLR-1758565 (PIs: Woodgate and Peralta-Ferriz). The mooring work required 2 dedicated cruises: - in 2021 (7th - 17th July), a ~ 11 day cruise on the US vessel Norseman2 deployed the moorings. Some CTD sections were run on this cruise, and those data are archived separately. - in 2022 (8th-19th September), a ~ 12 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 2021, 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. Unfortunately, mooring A2 was lost. Moorings carry a variety of instruments, listed in the file "Bering_Strait_Moorings_2021-2022_NSFAON_ReadMe_versFeb2024.txt" included in this dataset. For an overview of previous and on-going Bering Strait mooring work and related publications, please see PI web site, the above file, and publications listed in the Documentation section.

This is an archive of data from moorings deployed in Bering Strait from summer 2013 to summer 2014. Mooring deployments were funded by the ONR award N00014-13-1-0468 (PI: Woodgate) with shiptime support from the concurrent NSF-AON awards (Award ARC0855748, PIs: Woodgate, Weingartner, Lindsay and Whitledge; and Award PLR-1304052, PIs: Woodgate, Heimbach and Nguyen), in collaboration with the NOAA RUSALCA (Russian-US Long Term Census of the Arctic) program. The mooring work required 2 dedicated cruises. In 2013 (3rd - 10th July), a ~ 8 day cruise on the US vessel Norseman2 deployed the moorings. Some CTD sections were run on this cruise, and those data are archived separately. In 2014 (30th June - 7th July), a ~ 8 day cruise on the US vessel Norseman2 deployed the moorings. Some CTD sections were run on this cruise, and those data are archived separately. For 2013 to 2014, a total of three moorings were deployed. Two moorings (A2 and A4) in the US channel of the strait and 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. 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 Alaska Coastal Current.
