From September 1981 to December 1999, this dataset contains physical, biological, and chemical measurements from radiometer, profiling reflectance radiometer, and CTD casts collected worldwide. It was submitted by NASA's Goddard Space Flight Center as part of the SeaWiFS/SIMBIOS project for sensor intercomparison and oceanic studies.
Use Cases
- Calibrating and validating satellite ocean color sensors based on in-situ radiometer measurements.
- Studying marine biogeochemical cycles using the collected chemical and biological data.
- Analyzing global ocean optical properties from profiling reflectance radiometer casts.
- Conducting sensor intercomparison studies for the SeaWiFS/SIMBIOS project.
Strengths
- Covers an 18-year time range from 1981 to 1999.
- Includes multi-faceted data types: physical, biological, and chemical measurements.
- Features a global spatial distribution of collection sites.
Limitations
- Last updated 1999-12-16 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
