Coastal Glider Physical Profile Data from the Northeast Pacific Ocean

Physical trajectory profile data from the Slocum glider 'ce_384' deployed in the Northeast Pacific Ocean off the coasts of Oregon and Washington. The dataset contains raw, unprocessed measurements of oceanographic properties like temperature and salinity, collected by the Ocean Observatories Initiative (OOI) Endurance Array. Data was preserved by the National Centers for Environmental Information (NCEI) after aggregation by the IOOS National Glider Data Assembly Center.

Use Cases

• Analyze vertical profiles of temperature and salinity to study coastal upwelling intensity and water mass structure.
• Map glider trajectory and density measurements to visualize cross-shelf and along-shelf variability in the coastal ocean.
• Use conductivity and temperature time-series data to validate or calibrate regional ocean circulation models.
• Investigate the relationship between physical properties like density and spatial coordinates to understand frontal dynamics.

Strengths

• Data covers a specific 6-day deployment from July 8 to July 13, 2020, providing a focused temporal snapshot.
• Includes multiple core physical oceanographic variables (temperature, salinity, conductivity, density) per profile.
• Data originates from the authoritative OOI Endurance Array and was processed through the IOOS National Glider Data Assembly Center pipeline.

Limitations

• The data is explicitly raw with no corrections or quality control algorithms applied, requiring user expertise for interpretation.
• The spatial coverage is limited to the specific trajectory of a single glider deployment over 6 days.
• The total number of data rows, profiles, or file size is unknown from the provided metadata.
