A bio-optical database collates biogeochemical and optical measurements from multiple Australian marine monitoring programs. The dataset includes HPLC chlorophyll, spectral absorptions, water leaving radiance, and atmospheric optical depth data. It is used to assess the accuracy of satellite ocean colour products for Australian waters.
Use Cases
- Validate satellite-derived chlorophyll a concentrations based on in-situ HPLC and spectrophotometric measurements.
- Assess algorithms for phytoplankton species composition based on full spectral absorption data.
- Calibrate ocean colour data products for Australian waters based on water leaving radiance and reflectance measurements.
- Quantify uncertainty in regional ocean colour products based on the collated biooptical and in-situ optical data.
- Support international space agencies in reducing bias towards Northern Hemisphere observations based on the contributed database.
Strengths
- Data is aggregated from multiple authoritative sources including the IMOS National Mooring Network, National Reference Stations, and legacy programs.
- The database underpins accuracy assessments for current and forthcoming satellite missions.
- File formats include WMS and WFS, suggesting standardized geospatial web service access.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
