Ocean Glider Trajectory Profile Data from the North Pacific

Physical trajectory profile data was collected by a Teledyne Webb Research Slocum 1000m thermal glider during a test deployment off the west coast of Hawai'i. The dataset contains measurements of oceanographic properties including temperature, salinity, conductivity, and density. The data were assembled by the IOOS National Glider Data Assembly Center and archived by NOAA's National Centers for Environmental Information in October 2013.

Use Cases

• Analyze vertical temperature and salinity profiles to identify oceanographic fronts and water masses.
• Map the glider's trajectory to study advection and dispersion processes in the North Pacific.
• Calculate derived properties like density and sound speed from the measured conductivity, temperature, and depth data.
• Validate satellite-derived sea surface temperature measurements with in-situ glider profile data.
• Assess glider performance and sensor accuracy during the test deployment phase for a trans-Pacific mission.

Strengths

• Data covers a continuous 45-day deployment period from August to October 2013.
• Includes multiple core physical oceanographic variables measured by a deep-diving (1000m) platform.
• Data underwent quality checks and standardization by the IOOS National Glider Data Assembly Center before archival.

Limitations

• The exact number of profiles, rows, and data resolution is unspecified.
• Data is from a single glider deployment, limiting spatial and temporal generalizability.
• Dataset is from 2013 and may not represent current ocean conditions.
