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 {"type": "Polygon", "coordinates": [[[123.47, -13.97], [124.64, -13.97], [124.64, -12.48], [123.47, -12.48], [123.47, -13.97]]]} 123.47 124.64 -13.97 -12.48 Benthic habitat Montara banks environmental impact assessment oil spill SHAPE-ZIP documentDigital DATA ACCESS - Download (Montara offshore banks substrata - reduced to 4m resolution) in Shapefile format.
