Rip 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 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...

متن کاملBottom-trawling along submarine canyons impacts deep sedimentary regimes
Many studies highlight that fish trawling activities cause seafloor erosion, but the assessment of the remobilization of surface sediments and its relocation is still not well documented. These impacts were examined along the flanks and axes of three headless submarine canyons incised on the Barcelona continental margin, where trawling fleets have been operating for decades. Trawled grounds alo...
