NESP TWQ Project 2.3.1 - Benthic light as ecologically validated GBR wide indicator for wa

A 2016-2018 project developed a water quality indicator based on benthic irradiance for the Great Barrier Reef. The project, associated with the Australian Ocean Data Network, created a new remote sensing algorithm and quantified near-daily benthic irradiance over 14 years. It aimed to establish irradiance thresholds for ecosystem health and assess region-specific drivers like river discharge.

Use Cases

• Developing ecological thresholds for coral health based on benthic light levels.
• Modeling cumulative risks for coral bleaching using irradiance as a limiting factor.
• Assessing regional water quality drivers, such as river discharge, from remote sensing data.
• Validating remote sensing algorithms for benthic irradiance against in-situ measurements.
• Informing reef management and reporting through prototype guideline values.

Strengths

• Project developed a new, ecologically validated remote sensing algorithm for benthic irradiance.
• Analysis includes near-daily data over a 14-year period for the Great Barrier Reef.
• Indicator is designed to directly feed into formal reef health reporting (Reef Plan report cards).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
