Beaufort Gyre Mooring A 2008-2009 Pressure and Temperature Records

Mooring A collected 39,274 samples of pressure, temperature, and salinity over a 428-day deployment in the Beaufort Gyre. The dataset was gathered by the SCIOPS organization and covers the period from 2008 to 2009. It includes data from a bottom pressure recorder, though data from other instruments like the upward-looking sonar were still being processed at the time of publication.

Use Cases

• Analyze temporal trends in bottom pressure to infer changes in ocean mass and circulation over the 428-day period.
• Correlate temperature and salinity measurements to study water mass characteristics and stratification in the Beaufort Gyre.
• Use the high-frequency pressure data (39,274 samples) to investigate tidal or sub-seasonal oceanic variability.

Strengths

• 39,274 data samples provide a high-resolution time series.
• Deployment lasted 428 days, offering over a year of continuous observations.
• Includes co-located measurements of pressure, temperature, and salinity.

Limitations

• The McLane Moored Profiler recorded 0 profiles, indicating a partial instrument failure or data loss.
• Data from the upward-looking sonar was not available at publication, limiting sea ice or surface layer analysis.
• The dataset is temporally stale, with the last update in 2009.
