Integrating legacy data and regional geology to anticipate carbonate sediment properties at new locations (Australia)
Integrating legacy data and regional geology to anticipate carbonate sediment properties at new locations (Australia)
The TIDE Research Hub is working with industry partners to develop a large database of geological and geotechnical data from the North-West Shelf of Australia (NWS), one of the largest carbonate-dominated shelves in the world, to better understand the geotechnical behaviour of carbonate sediments. Within this framework, this paper investigates the processes that control the carbonate content, grain size and degree of cementation of the near seabed sediments. The study demonstrates how the source of carbonate sediments, the amount of fluvial runoff, the hydrodynamics of the environment and palaeo sea level changes combine to govern seabed geology. This knowledge has been used to develop a reasoning framework for predicting seabed conditions at other sites affected by similar processes thereby highlighting the potential for using geological analogues and historical data to assess ground conditions at new project locations.
