Journal Article
Baker, M. L., Talling, P. J., Burnett, R., Pope, E. L., Ruffell, S. C., Urlaub, M., Clare, M. A., Jenkins, J., Dietze, M., Neasham, J., Silva Jacinto, R., Hage, S., Hasenhündl, M., Simmons, S. M., Heerema, C. J., Heijnen, M. S., Kunath, P., Cartigny, M. J. B., McGhee, C., & Parsons, D. R. (2024). Seabed Seismographs Reveal Duration and Structure of Longest Runout Sediment Flows on Earth. Geophysical Research Letters, 51(23), Article e2024GL111078. https://doi.org/10.1029/2024gl111078

Turbidity currents carve the deepest canyons on Earth, deposit its largest sediment accumulations, and break seabed telecommunication cables. Powerful canyon‐flushing turbidity currents break sensors placed in their path, making them notoriously chal...

A threshold in submarine channel curvature explains erosion rate and type (2024)
Journal Article
Zulkifli, Z., Clare, M. A., Heijnen, M., Lintern, D. G., Stacey, C., Talling, P. J., Cartigny, M. J., Minshull, T. A., Moreno, H. M., Peakall, J., & Darby, S. (2024). A threshold in submarine channel curvature explains erosion rate and type. Earth and Planetary Science Letters, 646, https://doi.org/10.1016/j.epsl.2024.118953

Submarine channels are conduits for sediment-laden flows called turbidity currents, which play a globally significant role in the offshore transport of sediment and organic carbon and pose a hazard to critical seafloor infrastructure. Time-lapse repe... Read More about A threshold in submarine channel curvature explains erosion rate and type.

Time-lapse surveys reveal patterns and processes of erosion by exceptionally powerful turbidity currents that flush submarine canyons: A case study of the Congo Canyon (2024)
Journal Article
Ruffell, S. C., Talling, P. J., Baker, M. L., Pope, E. L., Heijnen, M. S., Jacinto, R. S., Cartigny, M. J., Simmons, S. M., Clare, M. A., Heerema, C. J., McGhee, C., Hage, S., Hasenhündl, M., & Parsons, D. R. (2024). Time-lapse surveys reveal patterns and processes of erosion by exceptionally powerful turbidity currents that flush submarine canyons: A case study of the Congo Canyon. Geomorphology, 463, Article 109350. https://doi.org/10.1016/j.geomorph.2024.109350

The largest canyons on Earth occur on the seafloor, and seabed sediment flows called turbidity currents play a key role in carving these submarine canyons. However, the processes by which turbidity currents erode submarine canyons are very poorly doc...

Globally significant mass of terrestrial organic carbon efficiently transported by canyon-flushing turbidity currents (2024)
Journal Article
Baker, M. L., Hage, S., Talling, P. J., Acikalin, S., Hilton, R. G., Haghipour, N., Ruffell, S. C., Pope, E. L., Jacinto, R. S., Clare, M. A., & Sahin, S. (2024). Globally significant mass of terrestrial organic carbon efficiently transported by canyon-flushing turbidity currents. Geology, 52(8), 631-636. https://doi.org/10.1130/g51976.1

Burial of organic carbon in marine sediments is a long-term sink of atmospheric CO2, and submarine turbidity currents are volumetrically the most important sediment transport process on Earth. Yet the processes, amounts, and efficiency of organic car... Read More about Globally significant mass of terrestrial organic carbon efficiently transported by canyon-flushing turbidity currents.

Morphometric fingerprints and downslope evolution in bathymetric surveys: insights into morphodynamics of the Congo canyon-channel. Frontiers in Earth Science, 12, Article 1381019. https://doi.org/10.3389/feart.2024.1381019

Submarine canyons and channels are globally important pathways for sediment, organic carbon, nutrients and pollutants to the deep sea, and they form the largest sediment accumulations on Earth. However, studying these remote submarine systems compreh...
