An estimated 8.3 billion tons of non-biodegradable plastic has been produced over the last
65 years. Much of this is not recycled and is disposed into the natural environment, has a …

Seafloor sediment flows, called turbidity currents, form the largest sediment accumulations,
deepest canyons and longest channels on Earth. It was once thought that turbidity currents …

Here we show how major rivers can efficiently connect to the deep-sea, by analysing the
longest runout sediment flows (of any type) yet measured in action on Earth. These seafloor …

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 …

In recent decades, the land-ocean aquatic continuum, commonly defined as the interface, or
transition zone, between terrestrial ecosystems and the open ocean, has undergone …

Seafloor sediment flows (turbidity currents) are among the volumetrically most important yet
least documented sediment transport processes on Earth. A scarcity of direct observations …

Seabed-hugging flows called turbidity currents are the volumetrically most important process
transporting sediment across our planet and form its largest sediment accumulations. We …

The interaction of deep-marine bottom currents with episodic, unsteady sediment gravity
flows affects global sediment transport, forms climate archives, and controls the evolution of …

Cyclic steps are a type of upper flow-regime bedform consisting of trains of upstream-and
upslope-migrating bed undulations. The overriding flow is characterised by a series of …

Rivers (on land) and turbidity currents (in the ocean) are the most important sediment
transport processes on Earth. Yet how rivers generate turbidity currents as they enter the …
