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...

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...

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...

Journal Article
Heerema, C. J., Cartigny, M. J., Jacinto, R. S., Simmons, S. M., Apprioual, R., & Talling, P. J. (2022). How distinctive are flood-triggered turbidity currents?. Journal of Sedimentary Research, 92(1), 1-11. https://doi.org/10.2110/jsr.2020.168

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?.

Preconditioning by sediment accumulation can produce powerful turbidity currents without major external triggers (2021)
Journal Article
Bailey, L. P., Clare, M. A., Rosenberger, K. J., Cartigny, M. J., Talling, P. J., Paull, C. K., …Lundsten, E. (2021). Preconditioning by sediment accumulation can produce powerful turbidity currents without major external triggers. Earth and Planetary Science Letters, 562, Article 116845. https://doi.org/10.1016/j.epsl.2021.116845

Turbidity currents dominate sediment transfer into the deep ocean, and can damage critical seabed infrastructure. It is commonly inferred that powerful turbidity currents are triggered by major external events, such as storms, river floods, or earthq...

Does Retrogression Always Account for the Large Volume of Submarine Megaslides? Evidence to the Contrary From the Tampen Slide, Offshore Norway (2020)
Journal Article

Evidence to the Contrary From the Tampen Slide, Offshore Norway. Journal of Geophysical Research. Solid Earth, 126(2), Article e2020JB020655. https://doi.org/10.1029/2020jb020655

Submarine landslides can be several orders of magnitude larger than their terrestrial counterparts and can pose significant hazards across entire ocean basins. The landslide failure mechanism strongly controls the associated tsunami hazard. The Tampe... Read More about Does Retrogression Always Account for the Large Volume of Submarine Megaslides?

Submarine channels are the primary conduits for terrestrial sediment, organic carbon, and pollutant transport to the deep sea. Submarine channels are far more difficult to monitor than rivers, and thus less well understood. Here we present 9 years of...
