A new study led by scientists from the National Oceanography Centre (NOC) and Durham University has revealed, for the first time, evidence of a giant landslide dam blocking megatonnes of organic carbon from being transported to deep-sea ecosystems.

Fast-moving waterfalls in the deep sea

Upper Channel 3D Perspective.

New research led by the National Oceanography Centre (NOC) has discovered how fast-moving waterfalls under the sea control the shape and behaviour of submarine channels.

Do deep-sea fish migrate?

The DELOS project is well matched with the NOC’s deep-ocean observation programme.

The first documented seasonal migrations of fish across the deep-sea floor has been revealed in research published today, involving NOC authors.

Major reductions in seafloor marine life from climate change by 2100

Large animals (megafauna), such as this hydroid Corymorpha glacialis, are projected to suffer major declines

A new study quantifies for the first time future losses in deep-sea marine life, using advanced climate models. Results show that even the most remote deep-sea ecosystems are not safe from the impacts of climate change.

Simple study advances seafloor ecological modelling

Seabed community biomass seems to increase continuously with individual body weight

A new study carried out at the National Oceanography Centre challenges a long accepted theory about how the biomass of animals living at the seafloor increases as animal size increases.

Results show that the complex trends detected by conventional sampling methods may be artefacts, and that the true relationship may be much simpler – and therefore easier to predict.
