CTD Hydrographic Profiles from RV Algoa in the Indian Ocean

Hydrographic profiles of water conductivity, temperature, and salinity collected by CTD from the research vessel Algoa in the Indian Ocean from April 9 to 15, 2016 for the Agulhas System Climate Array (ASCA) program. The data are stored in NetCDF format and were contributed by NOAA NCEI. It is listed on multiple platforms including NASA EarthData and Data.gov.

Use Cases

• Analyzing vertical profiles of conductivity, temperature, and salinity to study water mass properties.
• Investigating the dynamics and variability of the Agulhas Current region during the week-long survey.
• Calibrating and validating regional oceanographic models with in-situ CTD measurements.
• Assessing ocean heat content and salinity distribution for climate studies in the Indian Ocean.

Strengths

• Data provides a focused, week-long time-series from a dedicated research cruise for the ASCA program.
• Cross-platform presence on NASA EarthData and Data.gov indicates recognized scientific value and accessibility.

Limitations

• Key metadata such as row count, file size, and specific column names are unknown across all sources.
• Conflicting 'last updated' dates exist: one source reports 2016-04-15, while others report 2026-04-01, creating uncertainty about data currency.
