Seaglider Physical Oceanographic Measurements from Labrador Sea 2004-2005

Seaglider SG014, an autonomous underwater vehicle, collected oceanographic data during a seven-month mission from September 2004 to April 2005. The dataset includes measurements of temperature, salinity, and depth-averaged currents along a sawtooth trajectory through the Labrador Sea. Data was collected by the University of Washington and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyzing temperature and salinity profiles to study water mass formation and convection in the Labrador Sea.
• Estimating depth-averaged currents from glider trajectories to understand regional ocean circulation.
• Modeling the sawtooth dive trajectory data to optimize autonomous underwater vehicle mission planning.
• Calibrating remote sensing sea surface temperature data with in-situ glider measurements.

Strengths

• Data collected over a continuous 7-month deployment period.
• Measurements include multiple physical variables (temperature, salinity, currents) from a single platform.

Limitations

• Specific row count, column details, and data resolution are unknown.
• Data is from a single glider mission, limiting spatial coverage.
• Dataset is over 15 years old, which may limit relevance for studying recent ocean changes.
