Climate Linked Atlantic Sector Science (CLASS)

Three miles down, 30-year study, the giant amphipods are changing

Studying samples that date back to 1985, NOC scientists have discovered that the key scavengers of the deep-sea floor have changed in a way that matches changes in surface ocean climate. The work has also discovered a new species in the giant amphipod genus Eurythenes.

Deep-sea sponge vulnerable marine ecosystems under threat

NOC’s historic observations of the glass sponge Pheronema carpenteri in the Porcupine Seabight, NE Atlantic. Top row: original observations from 1983/4 (epibenthic sledge camera system); middle row: as observed in 1991 (WASP camera system); bottom row: specimens recovered in 1991, now held in the Discovery Collections.

Deep-sea sponges in the Porcupine Seabight (NE Atlantic), regarded as vulnerable marine ecosystems, appear to have declined dramatically in recent decades as a result of fishing, according to research published today.

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.

Research expedition assesses the continued ability of the North Atlantic to mitigate global heating

On 19 January an international research expedition led by scientists from the National Oceanography Centre (NOC) will be sailing from Fort Lauderdale in the USA to conduct a high precision scientific survey along 24.5°N of the North Atlantic.

Early career fellowships awarded for Atlantic Ocean research

A major NOC-led research programme, focused on the Atlantic Ocean, has awarded four fellowships to support early career researcher development.

These fellowships will also help address key knowledge gaps in Atlantic Ocean variability and climate regulation, as well as assessing how the Atlantic will change in response to human activity.
