Eastward and northward components of ocean current, temperature, salinity and ice analysis collected from industry sponsored moorings in the Chukchi Sea, Alaska from 2008-09-08 to 2016-10-13 (NCEI Accession 0164964)

Thirteen moorings sites throughout the northeastern Chukchi Sea shelf were occupied in various combinations for eight field years, 2008-2016. Two separate taut line moorings were deployed at most sites. The primary mooring employed at all sites deployed a Teledyne RDI Acoustic Doppler Current Profiler (ADCP) to measure water and sea ice velocities. Except at the locations over Hanna Shoals, 2011-2012, a second mooring deployed an Ice Profiling Sonar (IPS) instrument, manufactured by ASL Environmental Sciences Inc. (ASL), to measure ice keel depths and wave diagnostics, and a Sea Bird Electronics 37-SM CT sensor to measure water temperature and conductivity (and thus derive salinity). Moorings were deployed during the ice-free season, then recovered and redeployed in subsequent years. Data at the Crackerjack mooring location was collected until 2016 because though recovery was intended for 2015, weather delayed it until the next year.

Data collection was conducted by Olgoonik Fairweather LLC (Fairweather) of Anchorage, Alaska, and ASL, Victoria, B.C., Canada. Fairweather provided logistical support to ASL field personnel during oceanographic mooring recovery and redeployment, and ASL was contracted to collect and analyze data. UAF processing was limited to assembling the data into this data submission. NCEI received the data in text and MS Excel formats. The latter have been exported to CSV text.

Purpose This is a synthesis of multiple data sets collected from 2008 to 2015 in support of offshore production systems for the Chukchi Sea exploration lease areas by Shell International Exploration and Production Inc. (Shell), ConocoPhillips Alaska Inc. (CPAI or COP), and Statoil. Data were provided to Dr. Tom Weingartner to be incorporated into an overall analysis of Chukchi Sea currents funded by the US Dept. of the Interior, Bureau of Ocean Energy Management (BOEM) through Cooperative Agreement #M12AC00008 ("Characterization of the Circulation on the Continental Self Areas of the Northern Chukchi and Western Beaufort Seas.")

Processing Steps
  • Data Type: CONDUCTIVITY (measured); Units: mS/cm; Observation Type: in situ; Sampling Instrument: CTD - moored CTD.
  • Data Type: SALINITY - BOTTOM WATER (measured); Units: psu; Observation Type: other; Sampling Instrument: CTD - moored CTD; Sampling and Analyzing Method: Salinity was calculated from measured conductivity and temperature, with a constant pressure value based on the CT sensor's depth.
  • Data Type: TEMPERATURE - BOTTOM WATER [WATER TEMPERATURE] (measured); Units: degrees Celsius; Observation Type: in situ; Sampling Instrument: CTD - moored CTD.
  • Data Type: CURRENT METER - EAST-WEST COMPONENT (U) (measured); Units: cm/s; Observation Type: in situ; Sampling Instrument: ADCP; Sampling and Analyzing Method: ADCP current data is presented at 3 depths - bottom, mid-depth, and surface. The surface measurement was produced using a process that accounts for contamination by surface reflections and ice drafts. This procedure is detailed in ASL's reports.
  • Data Type: CURRENT METER - NORTH-SOUTH COMPONENT (V) (measured); Units: cm/s; Observation Type: in situ; Sampling Instrument: ADCP; Sampling and Analyzing Method: ADCP current data is presented at 3 depths - bottom, mid-depth, and surface. The surface measurement was produced using a process that accounts for contamination by surface reflections and ice drafts. This procedure is detailed in ASL's reports.
  • Data Type: PRESSURE - WATER [HYDROSTATIC PRESSURE] (measured); Units: dbar; Observation Type: in situ; Sampling Instrument: Ice Profiling Sonar (IPS).
  • Data Type: ICE - MOVEMENT - DIRECTION (measured); Units: cm/s; Observation Type: in situ; Sampling Instrument: ADCP.
  • Data Type: ICE - MOVEMENT - SPEED (measured); Units: cm/s; Observation Type: in situ; Sampling Instrument: ADCP.
  • Data Type: Ice Depth/Thickness (measured); Units: m; Observation Type: in situ; Sampling Instrument: Ice Profiling Sonar (IPS); Sampling and Analyzing Method: The IPS instrument is an upward-looking ice profiling sonar, which provides the ice draft data required for characterizing the winter oceanic environment. Originally, this instrument was designed by the Institute of Ocean Sciences, Victoria, BC, Canada, and has been further developed and subsequently manufactured by ASL. The ice keel depth is determined from the return travel time of an acoustic pulse (420 kHz; 1.8° beam at -3 dB) reflected off the underside of the sea ice. The return time is converted to an acoustic range value using the speed of sound in seawater.
  • Data Type: WAVE HEIGHT - SIGNIFICANT (measured); Units: m; Observation Type: in situ; Sampling Instrument: Ice Profiling Sonar (IPS).
  • Data Type: WAVE PERIOD (measured); Units: s; Observation Type: in situ; Sampling Instrument: Ice Profiling Sonar (IPS).
  • Data Type: WATER LEVEL (measured); Units: m; Observation Type: in situ; Sampling Instrument: Ice Profiling Sonar (IPS).
