Boaty McBoatface returns from first mission under the ice

The yellow high-tech autonomous underwater vehicle (AUV), affectionately known as Boaty McBoatface, has successfully returned from an ambitious science expedition deep below half a kilometre of ice.

Warm summers could weaken ocean circulation

Deep convection in the North Atlantic is one of the key components of large-scale ocean circulation. Based on long-term observations, scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel have now demonstrated ...

Warmer, saltier polar water could change global ocean currents

Melting ice shelves are changing the ocean's chemistry at the South Pole and the result could be a change in global currents and increased glacial melt, according to scientists who are creating maps to feed into climate change ...

Tracking ocean salinity from space using colour

Measuring salinity at the ocean's surface is important for tracking global ocean circulation as well as local ecosystem health. A research team from Universiti Malaysia Terengganu have proposed a new method to measure sea ...

Ocean floor mud reveals secrets of past European climate

Samples of sediment taken from the ocean floor of the North Atlantic Ocean have given researchers an unprecedented insight into the reasons why Europe's climate has changed over the past 3000 years.

How a 'shadow zone' traps the world's oldest ocean water

New research from an international team has revealed why the oldest water in the ocean in the North Pacific has remained trapped in a shadow zone around 2km below the sea surface for over 1000 years.
