Submarine Canyons: Their role in shaping biodiversity patterns on the Australian margin
Submarine canyons are recognised as potential areas of high biological productivity and marine life aggregation, in Australia ranging from deep water corals to foraging blue whales. While factors such as nutrient upwelling and the presence of hard substrate can account for the biodiversity of particular canyons, the variability of these characteristics between canyons at the national scale is p...
متن کاملRip Currents Onshore Submarine Canyons
The long-term goals of this research are to understand the dynamics of rip currents generated by largescale variations in alongshore pressure gradients and wave forcing, and the impact of rip currents on nearshore bathymetry. These goals will be accomplished collaboratively using field observations and numerical models, and will be pursued as part of the Nearshore Canyon Experiment (NCEX) sched...
متن کاملMegafaunal Benthic Ecology of the Submarine Canyons of Southern California
Submarine canyons have been studied to a very limited extent in spite of their important biological roles as hotspots of secondary production and organic matter conduits between the shelf and the deep sea. The heterogeneity and rugged terrain of submarine canyons makes them difficult to sample using traditional means such as trawling, however there has be a great deal of success in using ROVs t...
متن کاملCirculation Near Submarine Canyons: A Modeling Study
Circulation near a submarine canyon is analyzed with a numerical model. Previous theoretical work indicated that stratification controlled the interaction of coastal flow with canyons, specifically, the ratio of canyon width to the internal radius of deformation. A wide canyon was thought to merely steer the flow, while a narrow canyon would create substantia• cross-shelf exchange. Four cases a...
