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...

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...

Submarine landslides pose a hazard to coastal communities and critical seafloor infrastructure, occurring on all of the world's continental margins, from coastal zones to hadal trenches. Offshore monitoring has been limited by the largely unpredictab...

The Global Turbidity Current Pump and Its Implications for Organic Carbon Cycling (2023)
Journal Article
Talling, P. J., Hage, S., Baker, M. L., Bianchi, T. S., Hilton, R. G., & Maier, K. L. (2024). The Global Turbidity Current Pump and Its Implications for Organic Carbon Cycling. Annual Review of Marine Science, 16(1), https://doi.org/10.1146/annurev-marine-032223-103626

Submarine turbidity currents form the largest sediment accumulations on Earth, raising the question of their role in global carbon cycles. It was previously inferred that terrestrial organic carbon was primarily incinerated on shelves and that most t...

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.

Time‐Lapse Seafloor Surveys Reveal How Turbidity Currents and Internal Tides in Monterey Canyon Interact With the Seabed at Centimeter‐Scale (2023)
Journal Article
Wolfson‐Schwehr, M., Paull, C. K., Caress, D. W., Gwiazda, R., Nieminski, N. M., Talling, P. J., …Troni, G. (2023). Time‐Lapse Seafloor Surveys Reveal How Turbidity Currents and Internal Tides in Monterey Canyon Interact With the Seabed at Centimeter‐Scale. Journal of Geophysical Research: Earth Surface, 128(4), https://doi.org/10.1029/2022jf006705

Here we show how ultra-high resolution seabed mapping using new technology can help to understand processes that sculpt submarine canyons. Time-lapse seafloor surveys were conducted in the axis of Monterey Canyon, ∼50 km from the canyon head (∼1,840...

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...

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...
