Montara offshore banks substrata mapping
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

- Statement
- Nine banks and shoals were surveyed in 2011 with high resolution multibeam swath bathymetry, ranging in distance from within three kilometres to around 150 km from the Montara well. With the exception of Vulcan and Barracouta shoals, all were poorly described, with limited bathymetric data. Multibeam swath mapping was undertaken using a Reson Seabat 7101 and post-processed to 2m pixel size. At each bank and shoal, video transects and sediment samples were conducted to assess biotic communities and substratum, and investigate exposure to hydrocarbons. A total of 16,000 still images from towed video were used for substratum and habitat analysis. Extensive biological and ecological surveying was carried as part of this survey, see https://www.dcceew.gov.au/sites/default/files/env/pages/bcefac9b-ebc5-4013-9c88-a356280c202c/files/2011-offshore-banks-assessment-survey.pdf
