Mooring A collected oceanographic and sea ice data in the Beaufort Gyre region over a 362-day deployment from 2004 to 2005. The dataset includes over 15.6 million samples of ice draft, pressure, and temperature from an upward-looking sonar, 322 profiles of salinity and horizontal velocity from a moored profiler, and over 20,000 samples of bottom pressure, temperature, and salinity. The data was collected by the Beaufort Gyre Exploration Project under the organization SCIOPS and was last updated in March 2006.
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 and salinity to investigate water mass properties and density.
- Use McLane Moored Profiler profiles of horizontal velocity and salinity to calculate ocean currents and freshwater transport.
- Combine pressure, temperature, and ice draft time-series to model heat exchange between the ocean and sea ice.
Strengths
- High-resolution time-series with over 15.6 million ice draft, pressure, and temperature samples from the upward-looking sonar.
- Multi-instrument deployment providing 322 detailed ocean profiles and over 20,000 bottom pressure records over 362 days.
Limitations
- Data is from a single mooring location, limiting spatial representativeness.
- Temporally limited to a single year-long deployment from 2004-2005, which may not represent current Arctic conditions.
