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 …

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 …

The threat posed by plastic pollution to marine ecosystems and human health is under
increasing scrutiny. Much of the macro-and microplastic in the ocean ends up on the …

Volcanic eruptions on land create hot and fast pyroclastic density currents, triggering
tsunamis or surges that travel over water where they reach the ocean. However, no field …

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 distinction between turbidites, contourites and hemipelagites in modern and ancient
deep-water systems has long been a matter of controversy. This is partly because the …

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 …

Marine litter is an emerging environmental threat affecting all world's oceans including the
deep seafloor, where the extent of the phenomenon is still largely unknown. We report the …

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 …

Interactions between along-slope bottom currents and down-slope turbidity flows can create
a myriad of features and deposits. Despite numerous efforts to differentiate contourites from …
