Sedimentation of two contrasting continental shelf environments have been investigated. Numerical ocean models were used to assess the oceanic processes which dominate Torres Strait and the Gulf of Papua, Northern Australia, and then the ocean cavity beneath the Amery Ice Shelf, East Antarctica. A three-dimensional, numerical ocean model (MECO) was applied to the Torres Strait/Gulf of Papua region at 0:05 degree resolution. Validation of the model was carried out against current meter and sea-level observational data. Dispersal pathways of sediments, derived from the Fly River, Papua New Guinea, and from a resuspension event on the Northern Great Barrier Reef, into Torres Strait were investigated via the introduction of passive tracers into the model. Sediment input into Torres Strait is found to be greater during the Trade season by approximately 10%. Wave data was also obtained, and together with hydrodynamic model output, sediment mobility due to currents, waves and wave-current interactions was ...
