Seaglider Physical Oceanographic Measurements from Labrador Sea 2004-2005

Seaglider SG015 collected temperature, salinity, and depth-averaged current data in the Labrador Sea from September 24, 2004, to March 31, 2005. The autonomous underwater vehicle executed sawtooth dive profiles, transmitting measurements in near real-time. NOAA's National Centers for Environmental Information (NCEI) archives this dataset under accession 0111844.

Use Cases

• Analyze temporal trends in water temperature and salinity profiles to study seasonal changes in the Labrador Sea.
• Calculate depth-averaged currents from glider trajectory data to investigate local ocean circulation patterns.
• Validate regional ocean model outputs using in-situ temperature and salinity measurements collected along the glider path.
• Study the vertical structure of the water column using the high-resolution dive profile data from the sawtooth trajectory.

Strengths

• Data collected over a continuous 6-month deployment period from September 2004 to March 2005.
• Includes core physical oceanography variables: temperature, salinity, and depth-averaged currents.
• Measurements transmitted in near real-time, indicating potential for operational quality control.

Limitations

• Exact sample size (number of dives or data points) and spatial resolution are unknown.
• Dataset is temporally stale, with the last update recorded in March 2005.
• Limited geographic scope focused solely on the Labrador Sea deployment track.
