NASA omi Project: Upper Ocean Salinity and Temperature Profiles near Guam

Near Guam (14°N 144°E), three autonomous Seagliders collected profiles of salinity and temperature from October 2019 to January 2020. The project, led by the University of Washington Applied Physics Laboratory, aimed to measure oceanic response to rain in real-time using an adaptive sampling formation. Data is gridded by profile on depth bins from 0 to 1000 meters and is available in Level 2 and Level 3 processed netCDF files.

Use Cases

• Modeling the spatial patchiness of salinity based on adaptive glider formation data.
• Analyzing the real-time oceanic response to tropical rain events based on concurrent radar measurements.
• Studying temperature-salinity profiles in the upper 1000 meters of the ocean.
• Developing or validating autonomous sampling strategies for marine environments.

Strengths

• Data covers a specific campaign from October 2019 to January 2020 with a clear geographic focus near Guam.
• Includes two processing levels (Level 2 gridded, Level 3 despiked and interpolated) providing flexibility for analysis.
• Sampling was designed for real-time adaptive measurement of rain-driven events, suggesting targeted data collection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
