Seaglider Physical Oceanographic Measurements from Hawaiian Coastal Waters

Physical oceanographic data collected by an autonomous Seaglider vehicle during a nine-day mission in November 2004. The dataset includes measurements of temperature, salinity, and depth-averaged current along a sawtooth trajectory through the water column. Data was collected by the University of Washington and archived by NOAA NCEI.

Use Cases

• Analyze vertical temperature and salinity profiles to identify thermocline and halocline structures in Hawaiian coastal waters.
• Calculate depth-averaged currents from glider navigation data to study coastal circulation patterns.
• Correlate sensor measurements from the sawtooth trajectory to map water mass properties over the mission's spatial range.
• Validate and calibrate regional oceanographic models using in-situ temperature and salinity observations.

Strengths

• Data collected via a specialized autonomous underwater vehicle designed for long-duration missions.
• Includes core physical oceanography variables: temperature, salinity, and depth-averaged current.

Limitations

• Dataset size, row count, and specific column details are unknown.
• Temporal coverage is limited to a single nine-day mission in late 2004.
• Geographic scope is restricted to a specific deployment area in Hawaiian coastal waters.
