Seaglider Oceanographic Measurements from Labrador Sea 2005

Seaglider SG016 collected temperature, salinity, and depth-averaged current data during a 9-month mission in the Labrador Sea from April 2005 to January 2006. The autonomous underwater vehicle was developed by the University of Washington and deployed by NOAA's National Centers for Environmental Information. This dataset captures physical ocean properties along a sawtooth glider trajectory.

Use Cases

• Analyze temperature and salinity profiles to study water mass formation in the Labrador Sea.
• Model depth-averaged current measurements to understand regional ocean circulation patterns.
• Validate satellite-derived sea surface salinity data using in-situ glider measurements.
• Study the temporal evolution of oceanographic properties over the 9-month deployment period.

Strengths

• Data collected over a continuous 9-month mission from April 2005 to January 2006.
• Measurements include key physical oceanographic variables: temperature, salinity, and currents.
• Deployed in the scientifically significant Labrador Sea, a region critical for deep water formation.

Limitations

• The dataset is from a single glider (SG016), limiting spatial coverage.
• Data is over 15 years old, which may not reflect current ocean conditions.
• Specific row count, sampling resolution, and data completeness are unknown.
