Modelling what substrates make up the NW shoals of the Timor Sea

Submerged reefs and shoals are important features of the North West Marine Region of Australia due to their diverse and often unique benthic (e.g., corals, sponges) and fish biodiversity. In 2009, reefs and shoals near the Montara oil field were exposed to an uncontrolled release of oil and gas that lasted for 74 days.

In response, PTTEP commissioned a new world class body of independent scientific research into the marine life and ecosystems of the Timor Sea. Spatial scientists at the Australian Institute of Marine Science used high resolution multibeam data collected during PTTEP-funded field surveys to predict the types and distribution of substrate that make up each shoal, as shown below:
