Bering Strait Mooring Data 2014-2015

This is an archive of metadata from moorings deployed in Bering Strait from
summer 2014 to summer 2015.
Mooring deployments were funded by the NSF-Arctic Observing Network
award PLR-1304052 (PI: Woodgate, Heimbach and Nguyen), in collaboration
with the NOAA RUSALCA (Russian-US Long Term Census of the Arctic) program.
For 2014 to 2015, 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 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.

For access to the data, please visit NODC or our website.
Moorings carry a variety of instruments, listed in the attached table.
All records are year-round, sampling hourly or more frequently (Time
Int. in attached table).
Data from instruments marked with * are not included in the NODC archive.
For access to these data, please contact the named PI in list below.
Depths are estimated from mooring design and pressure sensors where available,
and are good to 1-2m.
