Beaufort Gyre Exploration Project Mooring B collected oceanographic and sea ice data over a 378-day deployment from 2006 to 2007. The dataset includes over 14.7 million samples of ice draft from an upward looking sonar, 302 profiles from a moored profiler, and 32,820 bottom pressure recorder samples. The project was conducted by the SCIOPS organization, with data last updated in March 2008.
Use Cases
- Analyze temporal trends in ice draft from the upward looking sonar to study sea ice thickness variability.
- Correlate bottom pressure recorder measurements with temperature to investigate deep water column processes.
- Use McLane Moored Profiler profiles of salinity and horizontal velocity to model ocean circulation and freshwater storage in the Beaufort Gyre.
- Combine pressure, temperature, and ice draft time-series to validate coupled ocean-ice climate models.
Strengths
- High-resolution ice draft data with 14,766,800 samples from the upward looking sonar.
- Continuous temporal coverage from a 378-day mooring deployment.
- Multisensor integration providing pressure, temperature, salinity, velocity, and ice draft.
Limitations
- Data is temporally limited to a single annual cycle from 2006-2007.
- Geographic coverage is limited to the specific location of Mooring B in the Beaufort Gyre.
- Unknown data quality flags or sensor calibration details for the raw samples.
