Seaglider SG660 CTD Measurements in the Southern and South Indian Oceans, 2019

NCEI Accession 0228185 contains water temperature, salinity, dissolved oxygen, and other variables collected by a seaglider in the Southern and South Indian Oceans from May to July 2019. The data were gathered during the SOGOS project, where the glider followed a SOCCOM biogeochemical float, and were processed using optimal interpolation. The dataset is provided in NetCDF format by NOAA NCEI.

Use Cases

• Modeling ocean submesoscale dynamics based on high-resolution temperature and salinity profiles.
• Analyzing biogeochemical cycles based on dissolved oxygen and chlorophyll fluorescence data.
• Calibrating and validating satellite-derived oceanographic products based on in-situ CTD measurements.
• Studying water mass properties and frontal structures in the Southern Ocean based on the gridded spatial data.

Strengths

• Includes multiple oceanographic variables: temperature, salinity, dissolved oxygen, optical backscatter, and chlorophyll fluorescence.
• Data were collected during a targeted scientific mission (SOGOS) following a biogeochemical float.
• Data were processed using an optimal interpolation method to create a gridded product.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2019-07-25; freshness should be verified for current applications.
• Row count and file size are unknown, which may limit suitability assessment.
