The shape and size of sedimentary bedforms play a key role in the reconstruction of sedimentary processes in modern and ancient environments. Recent laboratory experiments have shown that bedforms in mixed sand–clay develop at a slower rate and ofte...

The interaction of marine (tides and waves) and fluvial processes determines the sedimentary fill of coastal systems in the fluvial-tomarine (FTM) transition zone. Despite frequent recognition of tidal and wave i... Read More about Controls on mud distribution and architecture along the fluvial-to-marine transition.

Carbon and sediment fluxes inhibited in the submarine Congo Canyon by landslide-damming (2022)
Journal Article

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...

Chemical communication via infochemicals plays a pivotal role in ecological interactions, allowing organisms to sense their environment, locate predators, food, habitats, or mates. A growing number of studies suggest that climate change-associated st... Read More about Becoming nose-blind—Climate change impacts on chemical communication.

First source-to-sink monitoring shows dense head controls sediment flux and runout in turbidity currents (2022)

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...
