Hasenhündl, M., Talling, P. J., Pope, E. L., Baker, M. L., Heijnen, M. S., Ruffell, S. C., …Cartigny, M. J. B. (2024). 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...

Predicting turbidity current activity offshore from meltwater-fed river deltas (2023)
Journal Article
Bailey, L. P., Clare, M. A., Pope, E. L., Haigh, I. D., Cartigny, M. J., Talling, P. J., …Heijnen, M. (2023). Predicting turbidity current activity offshore from meltwater-fed river deltas. Earth and Planetary Science Letters, 604, Article 117977. https://doi.org/10.1016/j.epsl.2022.117977

Quantification of the controls on turbidity current recurrence is required to better constrain land to sea fluxes of sediment, carbon and pollutants, and design resilient infrastructure that is vulnerable to such flows. This is particularly important... Read More about Predicting turbidity current activity offshore from meltwater-fed river deltas.

Carbon and sediment fluxes inhibited in the submarine Congo Canyon by landslide-damming (2022)
Journal Article
Pope, E. L., Heijnen, M. S., Talling, P. J., Jacinto, R. S., Gaillot, A., Baker, M. L., …Urlaub, M. (2022). Carbon and sediment fluxes inhibited in the submarine Congo Canyon by landslide-damming. Nature Geoscience, 15(10), 845-853. https://doi.org/10.1038/s41561-022-01017-x

Landslide-dams, which are often transient, can strongly affect the geomorphology, and sediment and geochemical fluxes, within subaerial fluvial systems. The potential occurrence and impact of analogous landslide-dams in submarine canyons has, however...

Stratigraphic record reveals contrasting roles of overflows and underflows over glacial cycles in a hypersaline lake (Dead Sea) (2022)
Journal Article
Lu, Y., Pope, E. L., Moernaut, J., Bookman, R., Waldmann, N., Agnon, A., …Strasser, M. (2022). Stratigraphic record reveals contrasting roles of overflows and underflows over glacial cycles in a hypersaline lake (Dead Sea). Earth and Planetary Science Letters, 594, Article 117723. https://doi.org/10.1016/j.epsl.2022.117723

In lakes and oceans, links between modern sediment density flow processes and deposits preserved in long-term geological records are poorly understood. Consequently, it is unclear whether, and if so how, long-term climate changes affect the magnitude...

Longest sediment flows yet measured show how major rivers connect efficiently to deep sea (2022)
Journal Article
Talling, P. J., Baker, M. L., Pope, E. L., Ruffell, S. C., Jacinto, R. S., Heijnen, M. S., …Hilton, R. J. (2022). Longest sediment flows yet measured show how major rivers connect efficiently to deep sea. Nature Communications, 13(1), https://doi.org/10.1038/s41467-022-31689-3

Here we show how major rivers can efficiently connect to the deep-sea, by analysing the longest runout sediment flows (of any type) yet measured in action on Earth. These seafloor turbidity currents originated from the Congo River-mouth, with one flo... Read More about Longest sediment flows yet measured show how major rivers connect efficiently to deep sea.

Turbidity Currents Can Dictate Organic Carbon Fluxes Across River‐Fed Fjords: An Example From Bute Inlet (BC, Canada) (2022)
Journal Article
Hage, S., Galy, V., Cartigny, M., Heerema, C., Heijnen, M., Acikalin, S., …Talling, P. (2022). Turbidity Currents Can Dictate Organic Carbon Fluxes Across River‐Fed Fjords: An Example From Bute Inlet (BC, Canada). Journal of Geophysical Research: Biogeosciences, 127(6), https://doi.org/10.1029/2022jg006824

The delivery and burial of terrestrial particulate organic carbon (OC) in marine sediments is important to quantify, because this OC is a food resource for benthic communities, and if buried it may lower the concentrations of atmospheric CO2 over geo...

First source-to-sink monitoring shows dense head controls sediment flux and runout in turbidity currents (2022)
Journal Article
Pope, E. L., Cartigny, M. J., Clare, M. A., Talling, P. J., Lintern, D. G., Vellinga, A., …Vendettuoli, D. (2022). First source-to-sink monitoring shows dense head controls sediment flux and runout in turbidity currents. Science Advances, 8(20), Article eabj3220. https://doi.org/10.1126/sciadv.abj3220

Until recently, despite being one of the most important sediment transport phenomena on Earth, few direct measurements of turbidity currents existed. Consequently, their structure and evolution were poorly understood, particularly whether they are de...

Fill, flush or shuffle: How is sediment carried through submarine channels to build lobes? (2022)

Submarine channels are the primary conduits for land-derived material, including organic carbon, pollutants, and nutrients, into the deep-sea. The flows (turbidity currents) that traverse these systems can pose hazards to seafloor infrastructure such...

Re-channelization of turbidity currents in South China Sea abyssal plain due to seamounts and ridges (2021)
Journal Article
Yin, S., Pope, E. L., Lin, L., Ding, W., Gao, J., Wu, Z., …Li, J. (2021). Re-channelization of turbidity currents in South China Sea abyssal plain due to seamounts and ridges. Marine Geology, 440, Article 106601. https://doi.org/10.1016/j.margeo.2021.106601

Turbidity currents can be characterized as net-erosive, net-depositional or net-bypassing. Whether a flow is erosive, depositional or bypasses depends on the flow velocity, concentration and size but these can also be impacted by external controls su...
