The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Timeseries of temperature, salinity, ADCP velocity with ice track, nitrate, fluorescence, turbidity, dissolved oxygen collected from Bering Strait Moorings A2, A3, A4 in Bering Strait from 2023-07-07 to 2024-09-11 (NCEI Accession 0302481) |
| Abstract: | This is an archive of data from moorings deployed in Bering Strait from summer 2023 and to summer 2024. 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 2023 (4th-14th 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 2024 (8th-18th September), 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 2023, 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 2024, 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. For access to these data, please contact the named PI in list below table. -------------------------------------------------------------------------- ID Deployed Latitude Longitude Instrument S/N Time Inst.

Soundtrap - APL Marine Mammal Recorder, PI: Kate Stafford UW. 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. For some instruments (e.g., SBE16,37, SUNA, ADCP, raw data files and calibration information are also included. See file listings. 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. ----------------------------------------------------------------------------- For details of the measurements and their interpretation,as well as relevant papers please see references in the Documentation section.
