2003-2004 data from a mooring deployed for 362 days in the Beaufort Gyre. The dataset includes over 15.6 million samples of ice draft, pressure, and temperature from an upward-looking sonar, 180 profiles of salinity and velocity, and over 20,000 samples of bottom pressure, temperature, and salinity. It was collected by the Beaufort Gyre Exploration Project and managed by SCIOPS.
Use Cases
- Analyze temporal trends in ice_draft from the upward-looking sonar to study sea ice thickness variability.
- Correlate salinity and temperature profiles from the McLane Moored Profiler with horizontal_velocity data to understand water mass movement.
- Model bottom pressure records from the bottom pressure recorder as an indicator of ocean circulation changes.
- Use the 180 profiles of pressure, temperature, and salinity to validate or calibrate regional ocean circulation models.
Strengths
- Contains 15,628,919 samples of ice draft, pressure, and temperature from the upward-looking sonar.
- Includes 180 detailed vertical profiles of pressure, temperature, salinity, and horizontal velocity.
- Covers a continuous 362-day deployment period from 2003 to 2004.
Limitations
- Data is from a single mooring location, limiting spatial representativeness.
- The dataset is temporally stale, with collection ending in 2004 and no recent updates.
