Geology, 46(6), 563-566. https://doi.org/10.1130/g40095.1

Submarine channels have been important throughout geologic time for feeding globally significant volumes of sediment from land to the deep sea. Modern observations show that submarine channels can be sculpted by supercritical turbidity currents (seaf...

Quaternary evolution of high-latitude margins has, to a large degree been shaped by the advance and retreat of ice sheets. Our understanding of these margins and the role of ice sheets is predominantly derived from the polar North Atlantic during the...

Which triggers produce the most erosive, frequent and longest runout turbidity currents on deltas? (2018)
Journal Article

Subaerial rivers and turbidity currents are the two most voluminous sediment transport processes on our planet, and it is important to understand how they are linked offshore from river mouths. Previously it was thought that slope failures or direct... Read More about Which triggers produce the most erosive, frequent and longest runout turbidity currents on deltas?.

Multi-stage volcanic island flank collapses with coeval explosive caldera-forming eruptions (2018)
Journal Article
Hunt, J. E., Cassidy, M., & Talling, P. J. (2018). Multi-stage volcanic island flank collapses with coeval explosive caldera-forming eruptions. Scientific Reports, 8(1), Article 1146. https://doi.org/10.1038/s41598-018-19285-2

Volcanic flank collapses and explosive eruptions are among the largest and most destructive processes on Earth. Events at Mount St. Helens in May 1980 demonstrated how a relatively small (<5 km3) flank collapse on a terrestrial volcano could immediat...

A general model for the helical structure of geophysical flows in channel bends (2017)
Journal Article

Meandering channels formed by geophysical flows (e.g. rivers and seafloor turbidity currents) include the most extensive sediment transport systems on Earth. Previous measurements from rivers show how helical flow at meander bends plays a key role in... Read More about A general model for the helical structure of geophysical flows in channel bends.

Newly recognized turbidity current structure can explain prolonged flushing of submarine canyons (2017)
Journal Article
Azpiroz-Zabala, M., Cartigny, M., Talling, P., Parsons, D., Sumner, E., Clare, M., …Pope, E. (2017). Newly recognized turbidity current structure can explain prolonged flushing of submarine canyons. Science Advances, 3(10), Article e1700200. https://doi.org/10.1126/sciadv.1700200

Seabed-hugging flows called turbidity currents are the volumetrically most important process transporting sediment across our planet and form its largest sediment accumulations. We seek to understand the internal structure and behavior of turbidity c... Read More about Newly recognized turbidity current structure can explain prolonged flushing of submarine canyons.
