PESA WA Branch September Technical Luncheon: Building the regional understanding of the deep water geology and benthic ecology of the Great Australian Bight

Thursday, September 21, 2017 @ 12:00 - 14:00

Event Categories:

Guest Speaker: Andrew Ross

Andrew Ross is a research scientist based at CSIRO. He leads research projects focused on marine geology, the development of new hydrocarbon sensor devices and baseline and oil spill monitoring. He and his team have been involved in seeps surveys both in Australian basins and in the Gulf of Mexico. More recently he has commenced a series of research projects to characterise the geology of the Great Australian Bight. Dr Ross joined CSIRO in 2004 and has qualifications in marine biology, oceanography and petroleum geoscience.

Building the regional understanding of the deep water geology and benthic ecology of the Great Australian Bight

Andrew Ross

The Great Australian Bight (GAB) represents one of Australia’s most prospective frontier hydrocarbon exploration regions. Its largest subregion – the Ceduna sub-basin – is a deep (slope to abyss) area of 126,300 km2 with a 12 km deep sedimentary sequence that remains effectively untested. Knowledge of the Ceduna sub-basin’s geology is rapidly evolving following recent collection of 3D seismic data sets, but many questions remain about its geological evolution. The composition of the seabed biota and its ecology in the deep GAB was virtually unknown.

To address a range of geological and biological questions, the multidisciplinary Great Australian Bight Deepwater Marine Program (GABDMP) aims to build a more comprehensive regional understanding of the geology of the deep (~700 to 4800 m) GAB, with a focus on rocky outcrops, seeps and volcanic seamounts, and to document aspects of the biota and benthic ecology for the first time.

This PESA Lunch presentation will walk through some of the facets of the program, including the marine survey approach and technology implemented to collect the data and samples, the samples collected and their interpretation in context of the local and basin context.
