NESP TWQ 5.2: Cumulative Stressor Impacts on the Great Barrier Reef, 2019-2020

Experimental analyses of concentration-response relationships for selected species under controlled local stressors and climate scenarios inform ecological risk assessments for the Great Barrier Reef. The project produced exposure maps and ecological models to understand the contribution of individual disturbances within a cumulative framework. This data was published by the Australian Ocean Data Network and last updated in July 2026.

Use Cases

• Modeling ecological risk from multiple stressors based on experimental concentration-response relationships.
• Informing management priorities for catchments and regions based on exposure maps and ecological models.
• Setting future water quality thresholds for the Great Barrier Reef based on cumulative impact assessments.
• Analyzing the contribution of acute and chronic disturbances to reef health status.

Strengths

• Data is based on controlled experimental analyses of species under different climate scenarios.
• Project integrates exposure maps and ecological models to advance understanding of cumulative impacts.
• Results are intended to directly inform management under the Reef2050 Plan.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified despite the 2026 update date.
