Southern Ocean Seaglider CTD Measurements from the SOGOS Project, 2019

Seaglider SG659 collected water temperature, salinity, dissolved oxygen, and optical backscatter data in the Southern and South Indian Oceans from 2019-05-01 to 2019-07 26. The data were collected as part of the Southern Ocean observations of the submesoscale (SOGOS) project, following an Argo float from the SOCCOM program. Data are provided in NetCDF format and were processed using optimal interpolation.

Use Cases

• Modeling submesoscale ocean dynamics based on high-resolution temperature and salinity profiles.
• Analyzing biogeochemical cycles based on dissolved oxygen and chlorophyll fluorescence measurements.
• Calibrating or validating satellite-derived ocean data based on in-situ CTD measurements.
• Studying water column structure and variability in the Southern Ocean based on the gridded time-series data.

Strengths

• Includes multiple oceanographic variables: temperature, salinity, dissolved oxygen, and optical backscatter.
• Data were collected during a targeted scientific project (SOGOS) following a SOCCOM Argo float.
• Data were processed using optimal interpolation, suggesting a level of quality control.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2019-07-26 00:00:00; freshness should be verified.
• Row count and file size are unknown, which may limit suitability assessment.
