Oligotrophic Southern Pacific Ocean Measurements from R/V Latalante

Oceanographic measurements were collected in the oligotrophic Southern Pacific Ocean during a 1994 research cruise by the French vessel R/V Latalante. The dataset captures physical and chemical properties of the open ocean environment. It is managed and distributed by NASA's OB_DAAC.

Use Cases

• Analyzing relationships between ocean temperature, salinity, and density in a low-nutrient region.
• Studying optical properties like light absorption or scattering in clear Southern Pacific waters.
• Modeling baseline chemical conditions (e.g., dissolved oxygen, nutrients) in an oligotrophic ocean ecosystem.
• Validating satellite-derived ocean color or sea surface temperature data with in-situ measurements.

Strengths

• Data originates from a dedicated 1994 research cruise, providing a coherent snapshot of ocean conditions.
• Cross-platform presence on NASA EarthData and Data.gov indicates established curation and importance.
• Covers multiple earth science domains: ocean chemistry, optics, temperature, and salinity/density.

Limitations

• Critical metadata is missing: specific column names, row counts, and file sizes are unknown across all sources.
• The license is inconsistently reported as 'other-license-specified' or 'None', requiring verification.
• The temporal coverage is limited to the single year 1994.
