6.0 Summary: Ocean Science for Offshore and Coastal EngineeringGo back to program
About the project
The research in this Node was undertaken to enhance engineering design and operations through understanding and prediction of the physical oceanographic processes over the vast regions of operations, including the continental slope and down to the abyssal plain.
The research is to support some of the largest ocean developments in the world in a hostile environment where there are many oceanographic unknowns. While the work considers much of the WA marine region, the prime focus is the North West Shelf which has a number of unique physical characteristics.
- Project 6.1: To better understand how to manage current facilities and optimise the design of future facilities in West Australian coastal waters under the influence of climate change.
- Project 6.2: To better understand how we manage current facilities and optimise the design of future facilities on the North West Shelf and adjacent seas in the face of the intense forcing from tidally driven waves and currents.
- Project 6.3: To better understand how we use the new generation of instrument systems such as ocean gliders to obtain sustained observations of the ocean conditions in Western Australia.
- Analyse past field observations of internal tides at number sites on North West Shelf.
- Build laboratory models to study internal tide generation and dynamics.
- Build hybrid numerical models linking global ocean circulation models (BLUElink) with regional scale ocean models (ROMS).
- Develop very high resolution non-hydrostatic numerical ocean models to couple with regional ocean models.
- Build high resolution benthic boundary layer instruments for ocean measurements diverse sites on North West Shelf.
- Obtain understanding of internal tide dynamics in southern portions of North West Shelf; and
- Deploy ocean gliders monitor to obtain near-real time data from the continental shelf and slope regions.
