2004-2005 data from a mooring deployed for 362 days in the Beaufort Gyre. It contains over 20,800 bottom pressure recorder samples, 322 profiler casts, and more than 15.6 million upward-looking sonar samples of pressure, temperature, salinity, velocity, and ice draft. The dataset was collected by the SCIOPS organization and published in March 2006.
Use Cases
- Analyze ice draft and pressure time series from the upward-looking sonar to study sea ice thickness variability.
- Correlate temperature and salinity profiles from the McLane Moored Profiler with horizontal velocity data to examine water mass structure and currents.
- Use the long-term bottom pressure recorder data to investigate seasonal changes in ocean bottom pressure and infer geostrophic flow.
- Model ocean-ice heat exchange by combining the profiler's temperature and salinity data with the sonar's ice draft measurements.
- Validate regional climate models by comparing simulated oceanographic parameters against the in-situ pressure, temperature, and salinity records.
Strengths
- High-resolution time series from the upward-looking sonar, with over 15.6 million samples of pressure, temperature, and ice draft.
- Multivariate profiling from the McLane Moored Profiler, providing 322 concurrent profiles of pressure, temperature, salinity, and horizontal velocity.
- Continuous temporal coverage from a single mooring location over a full annual cycle of 362 days.
Limitations
- Data is temporally limited to a single deployment year (2004-2005), restricting analysis of long-term trends.
- Spatial coverage is from a single point location (Mooring B), limiting regional representativeness.
- Sample data and specific column definitions are unavailable, complicating initial data exploration and parsing.
