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 …

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 …

Climate, tectonics, and life influence the flux and caliber of sediment transported across
Earth's surface. These environmental conditions can leave behind imprints in the Earth's …

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 …

Until recently, despite being one of the most important sediment transport phenomena on
Earth, few direct measurements of turbidity currents existed. Consequently, their structure …

Turbidity currents dominate sediment transfer into the deep ocean, and can damage critical
seabed infrastructure. It is commonly inferred that powerful turbidity currents are triggered by …

Upper‐flow‐regime bedforms, including upper‐stage‐plane beds, antidunes, chutes‐and‐
pools and cyclic steps, are ubiquitous in glacigenic depositional environments characterized …

Particle-laden gravity flows, called turbidity currents, flow through river-like channels across
the ocean floor. These submarine channels funnel sediment, nutrients, pollutants and …

Submarine channels are the primary conduits for terrestrial sediment, organic carbon, and
pollutant transport to the deep sea. Submarine channels are far more difficult to monitor than …
