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 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.

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
Int. in table below).
Data from instruments marked with * are not included in this archive.

Each data file contains the data from one instrument-year - the listed year
in the mooring name is the year in which the mooring was deployed.

For non-ADCP instruments, calibrated data are recorded in one file per instrument
per year, with naming convention:
BeringStrait_yyyy_ID_III_#####.ttt
yyyy=Deployment year; ID=mooring ID; III=instrument type; #####=serial number;
ttt=indicates calibration, with .pre=pre-deployment calibration used,
.ppp=pre and post deployment calibrations merged.
The SBE-16 and 37 hexidecimal files (unaltered from the download) are also
included, indicated by extension .hex or .asc

For the ADCPs, there are multiple files per instrument.
BeringStrait_yyyy__ID_#####ADCPraw.000 = Binary download from the ADCP
(see notes below for multiple .000 files)
BeringStrait_yyyy__ID_#####_ADCPdeploytests.txt = pre deployment tests
BeringStrait_yyyy__ID_#####_ADCPrecoverytest.txt = post deployment tests
The remainder are ASCII conversions of the data, corrected for clock drift
and magnetic declination.
BeringStrait_yyyy__ID_#####.btm = ASCII bottom track data
(including ice range and velocity)
BeringStrait_yyyy__ID_#####.ins = ASCII instrument data
(e.g. heading, pitch, roll, temperature)
BeringStrait_yyyy__ID_#####_bin01.rdat = ASCII water velocity data in Bin 1
BeringStrait_yyyy__ID_#####.bin02.rdat = ASCII water velocity data in Bin 2
etc. (Bin depths are given in the data files)
Header information is included in each data file.
