The transport and vertical distribution of microplastics in the Mekong River, SE Asia (2024)
Journal Article
Mendrik, F., Hackney, C. R., Cumming, V. M., Waller, C., Hak, D., Dorrell, R., Hung, N. N., & Parsons, D. R. (2025). The transport and vertical distribution of microplastics in the Mekong River, SE Asia. Journal of hazardous materials, 484, Article 136762. https://doi.org/10.1016/j.jhazmat.2024.136762

Rivers are primary vectors of plastic debris to oceans, but sources, transport mechanisms, and fate of fluvial microplastics (<5 mm) remain poorly understood, impeding accurate predictions of microplastic flux, ecological risk and socio-economic impa...

Linear dynamics in turbulent stratified plane Poiseuille flow (2024)
Journal Article
Lloyd, C. J., & Dorrell, R. M. (2024). Linear dynamics in turbulent stratified plane Poiseuille flow. Journal of Fluid Mechanics, 999, Article A104. https://doi.org/10.1017/jfm.2024.1000

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...

Monopile-induced turbulence and sediment redistribution form visible wakes in offshore wind farms (2024)
Journal Article
Bailey, L. P., Dorrell, R. M., Kostakis, I., McKee, D., Parsons, D., Rees, J., Strong, J., Simmons, S., & Forster, R. (2024). Monopile-induced turbulence and sediment redistribution form visible wakes in offshore wind farms. Frontiers in Earth Science, 12, Article 1383726. https://doi.org/10.3389/feart.2024.1383726

Offshore wind farms are becoming an increasingly common feature in the marine environment as a renewable energy source. There is a growing body of evidence on the effects of wind farms on the seabed and its organisms. However, an important and unders...
