Bering Strait Moorings 2019-2021

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 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.

   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

Meta data
=========

1) Platform: Subsurface oceanographic moorings

2) Project title: Bering Strait

3) Data collection dates: September 2019 to July 2021

4) PI:   Rebecca Woodgate (woodgate@uw.edu)

5) Data collection method:
     Year-round moorings carrying
     - Sea-Bird temperature/conductivity and pressure recorders (SBE)
     - RDI 300kHz Workhorse Acoustic Doppler Current Profilers (ADCP)
     - APL data loggers for inductive data from ISCAT system

6) Data calibration method:
     Unless noted otherwise in the header on each data file, timestamps
     have been corrected for observed instrument clock drift.
     All times are given in GMT.
     For SBEs, calibration coefficients are given in header file.

  SBEs:
     - Generally pre and post calibrated by the manufacturer (indicated
       by suffix .ppp).  
     - pre and post calibrations linearly time-weighted through the
       deployment.
     - .pre suffix indicates only pre-cruise calibration used
     - just prior to recovery, a CTD cast was performed in the vicinity
       of the mooring as an attempt to provide and inwater calibration.
       This is found to be of inconsistent quality as a calibration check.
       Immediately after recovery, SBE instruments were placed in a stirred
       tank of sea water, to check immediate post deployment calibrations.
       For full details, see cruise report. These are both just informational checks
       to assess how well the post-cruise manufacturer's calibration captures
       the final in-water state. The final post-cruise calibration used is
       that from the manufacturer.

  ADCPS:  Tested by APL/manufacturer pre deployment.
     - compasses calibrated as per manufacturer's
       specifications in Seattle prior to deployment.  Estimated
       compass error is included in the header file
     - where available, at sea compass check also included in header file
     - direction corrected to true north, magnetic declination used is cited
       in the header.
     - data requiring speed of sound in water is corrected by the ADCP using
       the water temperature measured by the ADCP.
     - intensity of returned signals is not specially calibrated.

7) Instrumentation used:  (see table for sampling frequencies)
     Sea-Bird SBE16 recorders
     ISCAT loggers (SBE37 Microcat logging data to an APL-Logger)
     RDI 300 kHz Workhorse ADCP - bin size typically 2m 

8) Quality control procedures:
     Quality control provided by Rebecca Woodgate.
     ADCP data rely on ADCP internal temperature for speed of sound
       corrections.
     ADCP Data files are included for all bins up to the surface although
       bins near the surface contain much larger errors (likely due to
       surface effects) and should be treated with caution.

9) Data format:
     SBE data - ASCII, format given in individual headers
        (uncalibrated "hex", "asc" or "XML" data also included for SBEs)
     ADCP data - 2 formats: a) BINARY download file from ADCP and
                            b) ASCII conversion of these files (in 2m bins)


10) Data collection problems:
    By Mooring:
      - no significant problems.  One moorings (A3-19) required
    dragging due to biofouling.  All others released without dragging 
      - biofouling is a typical issue in the strait, and was still
    sigificant on these moorings, especially those in the water since
    2019.   The effect of this on the data is to make salinities appear
    erroreously fresh.  Estimates of the extent of this problem by
    instrument are given below and in the individual file headers.
    Photographic documentation of biofouling on recovery is available
    via cruise reports, included here and on the Bering Strait website:
    http://psc.apl.washington.edu/BeringStrait.html.

 - post cal not available, but other data show sensor        
  drift in the strait may be as large as 0.05-0.1psu too      
 fresh by end of year deployment                             
 - winter freezing temperatures suggest salinities ok then

 ** Data times irregular, only uncorrected logger time given
          
 A419  - SBE37  20935 - recovered
  - biofouling was extreme, but cell seemed clear             
  - clock 0 min fast by end of deployment                     
  - record linearly interpolated between pre & post cals      
 - test tank results suggest salinities still within         
 instrument specs on recovery, although winter temperatures  
 suggest in the second winter iscat is ~0.1psu too fresh  
  - Logger 21 - recorded no data (but overall no data loss as
  SBE37 was recovered)

 Due to the Covid Pandemic preventing a science party on the ship in 2020,
 no iscats were deployed on the 2020 moorings.

11) Other related data sets:
       This data set is a continuation of mooring measurements made in the
       Bering Strait almost continuously since 1990.  Mooring data have
       already been archived via the SBI project, managed by JOSS/EOS,
       and at NODC (now NCEI), and metadata at arcticdata.io and AOOS.
       For details see
        http://psc.apl.washington.edu/BeringStrait.html
        https://data.eol.ucar.edu/master_lists/generated/sbi/
        http://www.ncei.noaa.gov
       Since 2000, CTD sections have been run in the Bering Strait on
       the mooring cruises.  These data are also accessible via the http
       links above.

13) Data qualifications or warnings:
       See also Data collection problems.
       For data issues relevant to a specific deployment, see the
       individual headers.  In general:
       SBE data: Standard Sea-Bird limitations apply
            - estimated accuracy 0.02 deg C, 0.0012 S/m
              (corresponding to 0.02 psu), and < 1 db.
            - see header files for difference between pre and post calibration
              which are usually 0.03 psu or greater.
            - Note that post-calibrations on the SBE16s
              suggests salinity sensor drift during deployment of between
              0.02 and 0.1psu, and this should be considered if post
              calibrations are not available
            - Note also that clogging of the salinity cell during
              deployment will not be captured by the post calibration
              and thus generally ends of records should be suspected
              for anomalously low salinities, especially if the SBE
              is not mounted vertical.
       ADCP data: Standard RDI limitations apply
            - estimated accuracy
              ~ 0.5 cm/s for water velocities (~100 pings per ensemble)
              Estimated errors (given in the files) vary with bin and time
              ~ 1 cm/s for ice velocities (2 or 5 pings per ensemble)
              Estimated errors (given in the files) vary with time
              ~ 1 deg in direction (see header files)
              Range to ice - accurate to 1% of range to surface (i.e. ~ 0.4 m)
              ~ 0.4 deg C in temperature
              Note that ADCP range measurements are not corrected
              for pitch and roll.  For full discussion and correction,
              see: Woodgate and Holroyd, 2011, included in archive.
