The fluid mechanics of deep-sea mining

T Peacock, R Ouillon - Annual Review of Fluid Mechanics, 2023 - annualreviews.org
Fluid mechanics lies at the heart of many of the physical processes associated with the
nascent deep-sea mining industry. The evolution and fate of sediment plumes that would be …

Turbulence processes within turbidity currents

MG Wells, RM Dorrell - Annual Review of Fluid Mechanics, 2021 - annualreviews.org
Sediment-laden gravity currents, or turbidity currents, are density-driven flows that transport
vast quantities of particulate material across the floor of lakes and oceans. Turbidity currents …

A new modelling approach to sediment bypass prediction applied to the East Coast Basin, New Zealand

A Crisóstomo-Figueroa, AD McArthur… - …, 2021 - pubs.geoscienceworld.org
Predicting when turbidity currents are erosional or depositional (ie, leaving no depositional
record versus leaving a deposit) remains challenging. Here we combine observations from …
