Bering Strait Mooring Data, 2017-2018

This is an archive of data from moorings deployed in Bering Strait from summer 2017 to summer 2018. Mooring deployments were funded by the National Science Foundation (NSF)-Arctic Observing Network award PLR (Division of Polar Programs)-1304052 (PI (Principal Investigator): Woodgate, Heimbach and Nguyen). The mooring work required 2 dedicated cruises: - in 2017 (7th - 15th July), a ~ 9 day cruise on the US (United States) vessel Norseman2 deployed the moorings. Some CTD (conductivity, temperature, and depth) sections were run on this cruise, and those data are archived separately. - in 2018 (10th - 19th August), a ~ 10 day cruise on the US vessel. For 2017 to 2018, 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. Sites A2, and A3 were established in 1990. A2 and A3 have been occupied almost continuously (all years except 1996-1997) 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. For an overview of previous and on-going Bering Strait mooring work, please see http://psc.apl.washington.edu/BeringStrait.html. Moorings carry a variety of instruments, listed in the table below. All records are year-round, sampling hourly or more frequently (Time Interval. in table below). Data from instruments marked with * are not included in this archive.
