Description
The 2025 OceanXplorer field campaign collected in-situ oceanographic measurements in the Indian Ocean and eastern Atlantic Ocean to validate NASA's PACE satellite mission. Data includes ocean optical properties, phytoplankton pigments, organic carbon, community composition, and aerosol measurements. This dataset provides ground-truth observations across diverse water types, from clear ocean to turbid coastal waters.
Use Cases
Validating satellite-derived ocean color and phytoplankton biomass algorithms based on in-situ radiometry and pigment data.
Assessing phytoplankton community composition and physiology in relation to optical properties.
Calibrating atmospheric correction models for satellite data using coincident aerosol measurements.
Studying carbon cycling in marine ecosystems using measured organic carbon concentrations.
Strengths
Data collection was strategically timed to coincide with the second year of NASA's PACE mission for optimal validation.
Measurements span a wide range of oceanographic conditions, from low to high productivity waters and clear to turbid water types.
Campaign involved collaboration between NASA and OceanX, leveraging the advanced OceanXplorer research vessel.
Limitations
Key metadata such as row count, file size, and specific column names are unavailable across all platforms.
The dataset's license is listed as 'other-license-specified' on Data.gov but is 'None' on NASA Earthdata, indicating a conflict or lack of clarity.
Data descriptions are repeated verbatim across platforms, suggesting limited unique contextual or documentation depth.
