Mapping of Marine Environmental and Anthropogenic Pressures in Northern Australia

Northern Australian marine spatial data collated for pressure mapping, categorizing resource extraction, pollution, habitat modification, climate, and other factors. The dataset includes derived additive and multiplicative pressure hotspot maps to identify areas of high versus low risk for management benefit. The information was generated by the NESP MB A12 project and hosted by the Australian Ocean Data Network, with a last update recorded in 2026.

Use Cases

• Identifying cumulative impact hotspots based on additive pressure maps that weight multiple high-risk pressures.
• Prioritizing management interventions based on multiplicative hotspot maps that de-emphasize areas with multiple low-risk pressures.
• Assessing risk from specific activities like trawl fisheries, aquaculture, or seismic operations using the collated spatial layers.
• Informing marine spatial planning by integrating pressure maps with species distribution data and interaction matrices.

Strengths

• Includes multiple specific pressure sources such as Commonwealth trawl fisheries effort, aquaculture infrastructure, and cyclone intensity.
• Provides two derived analytical products: an additive pressure hotspots map and a multiplicative hotspot pressure map.
• Hosted by the authoritative Australian Ocean Data Network with a recorded update in 2026.

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.
