BioSCape CDOM Spectral Data for South African Coastal and Inland Waters

Spectral absorption and fluorescence characteristics of colored dissolved organic matter (CDOM) and coincident hyperspectral water remote sensing reflectance measurements collected during NASA's 2023 Biodiversity Survey of the Cape (BioSCape) field campaign. The dataset covers three coastal bays and four inland aquatic systems within South Africa's Greater Cape Floristic Region. It is provided by the National Aeronautics and Space Administration to support remote sensing algorithm development.

Use Cases

• Calibrating and validating satellite-derived CDOM retrieval algorithms using field-measured spectral absorption and fluorescence.
• Assessing spatial variability in dissolved organic matter characteristics across distinct coastal bays and inland water bodies.
• Linking hyperspectral water remote sensing reflectance with in-situ CDOM measurements for bio-optical model development.
• Studying the relationship between aquatic biodiversity hotspots and dissolved organic carbon dynamics in a unique floristic region.

Strengths

• Samples cover seven distinct aquatic systems, providing ecological contrast across three coastal bays and four inland water bodies.
• Data includes coincident field measurements of both CDOM spectral properties and hyperspectral remote sensing reflectance.
• Collected as part of a coordinated NASA field campaign (BioSCape) in 2023, ensuring methodological consistency.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date, with one reporting 2026-03-13 and another 2023-11 14.
