Seaglider Oceanographic Measurements from Washington Coast Deployment

Seaglider SG014 collected temperature, salinity, and depth-averaged current data via sawtooth glides in the North Pacific Ocean. The autonomous underwater vehicle was deployed by the University of Washington and data is archived by NOAA NCEI. The mission occurred from March 15 to September 10, 2007.

Use Cases

• Analyze temperature and salinity profiles to study coastal water mass structure and mixing.
• Model depth-averaged current measurements to understand near-shore circulation patterns.
• Validate regional ocean models using the high-resolution time-series data from the glider trajectory.
• Study seasonal changes in water properties from March to September 2007 off the Washington/Oregon coast.

Strengths

• Data collected over a nearly six-month continuous deployment from March to September 2007.
• Measurements include key physical oceanographic variables like temperature, salinity, and currents.
• Data originates from a well-established Seaglider platform developed by University of Washington researchers.

Limitations

• Specific row count, column details, and file formats are unknown.
• Data is from a single vehicle (SG014) in one region, limiting geographic generalizability.
• The dataset is from 2007, which may not represent current oceanographic conditions.
