Deep Canada Basin Mooring Temperature Salinity Velocity Data

61 profiles of temperature, salinity, and velocity were collected over 25 days from a McLane Moored Profiler in the deep Canada Basin. The data, part of the Beaufort Gyre Observing System, includes measurements from depths between 2100 m and 3040 m, with a subsequent year-long time series at a fixed depth. The dataset was published by SCIOPS in 2009.

Use Cases

• Analyze temporal changes in potential temperature (THETA) and salinity (S) to study deep water mass evolution.
• Calculate vertical velocity (W) and profiling speed (DPDT) to understand instrument performance and local water movements.
• Correlate east (U) and north (V) velocity components with pressure (pgrid) to map deep current structures.
• Use the time-encoded (TIME) and profile number (number) vectors to reconstruct the temporal sequence of 61 profiling events.

Strengths

• Contains 61 detailed oceanographic profiles from a single location.
• Measures multiple core variables: temperature, salinity, and 3D velocity.
• Data spans a significant depth range from approximately 2100 m to 3040 m.

Limitations

• Limited to 25 days of full-depth profiling before a mechanical failure.
• Subsequent year-long record is from a very narrow depth band (2144-2148 m), reducing vertical resolution.
• Data is from a single mooring location, limiting spatial representativeness.
