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 extensive studies into the marine life and ecosystems of the Timor Sea. This record describes the high resolution multibeam data collected by the Australian Institute of Marine Science during PTTEP-funded field surveys to predict the types and distribution of substrate that make up each shoal. The shoal maps are supplied in vector Shapefile format, resampled to 4m, and at native resolution (~2m) in Geotiff format, with the following substratum classes: 1 = Limestone (high relief), 2 = Limestone (low relief), 3 = Rubble, 4 = Mixed substrate, 5 = Sand and rubble, 6 = Sand
