Hurricanes move massive amounts of sediment from shallow reefs to deep oceans, affecting ecosystems long-term.

Organisms in the deep sea rely on gravity flows to lay down sediment and then make burrows beneath the seafloor, according to a new study.

Mining of polymetallic nodules from the seabed might lead to significant and long-lasting ecological changes -- both in the mined area, where surface sediments and the fauna living in and on it are ...

Plus, each claw kicks up a relatively small puff of sediment as it plucks its target off the seafloor. Impossible Metals aims ...

The deep-sea, covering more than 60% of the Earth's surface, is a realm of mystery. It hosts a diverse range of geological features, which are all subject ...

over a distance of 1,100 kilometres -- from the mouth of the Congo River through the Congo deep-sea fan and canyon system. These are the longest-runout sediment flows ever recorded. The flows also ...
