Linear dynamics in turbulent stratified plane Poiseuille flow (2024)
Journal Article

We investigate a turbulent stratified plane Poiseuille flow using linear models and nonlinear simulations. We propose the first complete explanation for the prolific and coherent backward (BWs)-and forward-propagating waves (FWs), which have been obs...

Modeling the Tilt of Bend-Traversing Turbidity Currents: Implications for Sinuous Submarine Channel Development (2024)
Journal Article
Crisóstomo-Figueroa, A., Dorrell, R. M., Amy, L., McArthur, A. D., & McCaffrey, W. D. (2024). Modeling the Tilt of Bend-Traversing Turbidity Currents: Implications for Sinuous Submarine Channel Development. Journal of Geophysical Research: Oceans, 129(10), Article e2023JC020131. https://doi.org/10.1029/2023JC020131

The controls on the development of submarine channel sinuosity are contested: slope gradient and Coriolis forcing have both been recognized as key governing factors: gradient via an inverse relationship (low sinuosity at high slope and vice versa), a...

Circulation of hydraulically ponded turbidity currents and the filling of continental slope minibasins (2024)
Journal Article
Reece, J. K., Dorrell, R. M., & Straub, K. M. (2024). Circulation of hydraulically ponded turbidity currents and the filling of continental slope minibasins. Nature communications, 15(1), Article 2075. https://doi.org/10.1038/s41467-024-46120-2

Natural depressions on continental margins termed minibasins trap turbidity currents, a class of sediment-laden seafloor density driven flow. These currents are the primary downslope vectors for clastic sediment, particulate organic carbon, and micro...

Benthic biology influences sedimentation in submarine channel bends: Coupling of biology, sedimentation and flow (2024)
Journal Article
Azpiroz-Zabala, M., Sumner, E. J., Cartigny, M. J., Peakall, J., Clare, M. A., Darby, S. E., Parsons, D. R., Dorrell, R. M., Özsoy, E., Tezcan, D., Wynn, R. B., & Johnson, J. (2024). Benthic biology influences sedimentation in submarine channel bends: Coupling of biology, sedimentation and flow. The Depositional Record, https://doi.org/10.1002/dep2.265

Submarine channels are key features for the transport of flow and nutrients into deep water. Previous studies of their morphology and channel evolution have treated these systems as abiotic, and therefore assume that physical processes are solely res...
