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...

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)
Journal Article

Fill, flush or shuffle: How is sediment carried through submarine channels to build lobes?. Earth and Planetary Science Letters, 584, Article 117481. https://doi.org/10.1016/j.epsl.2022.117481

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...

Near‐Bed Structure of Sediment Gravity Flows Measured by Motion‐Sensing “Boulder‐Like” Benthic Event Detectors (BEDs) in Monterey Canyon (2022)
Journal Article

Near‐Bed Structure of Sediment Gravity Flows Measured by Motion‐Sensing “Boulder‐Like” Benthic Event Detectors (BEDs) in Monterey Canyon. Journal of Geophysical Research: Earth Surface, 127(2), https://doi.org/10.1029/2021jf006437

The near-bed section of submarine gravity flows travels at the highest and most destructive speeds making direct measurements of this region of the flow difficult. Here results are presented from “boulder-like” Benthic Event Detectors (BEDs) that mea...

How distinctive are flood-triggered turbidity currents? (2022)
Journal Article

Turbidity currents triggered at river mouths form an important highway for sediment, organic carbon, and nutrients to the deep sea. Consequently, it has been proposed that the deposits of these flood-triggered turbidity currents provide important lon... Read More about How distinctive are flood-triggered turbidity currents?.
