Seaweed has been discovered in Antarctica 100 metres beneath the surface.

The seaweed was found by a research team using a remotely-operated vehicle (ROV) from a boat off the south-western Antarctic peninsula.

Samples have been collected for further examination.

Seaweed is known to store carbon (CO2) so finding it here is an exciting discovery as it reveals more about Antarctica and the role it could play in tackling climate change.

The type of seaweed that was discovered is called Palmaria decipiens.

It is a species of red algae, well adapted to the Antarctic environment, where there are permanent low water temperatures.

But finding it attached to the sea floor, at a depth of 100m, is new to science and experts are hoping it may live even deeper.

It is good news because seaweeds play a "huge role" in protecting the environment, as Professor Frithjof Kuepper, from the University of Aberdeen, explains:

"We know that carbon capture will be crucial to limiting global warming as we move forward, and seaweeds sequester (hide away) large amounts of CO2."

Seaweed also plays a huge role in marine ecosystems and provides food and protection for animals and fish.

So knowing it lives this deep means it is almost certainly playing some role in providing habitats for creatures to live in, as well as absorbing and storing carbon dioxide in the deep.

"Antarctica... is so important to understand for addressing the environmental challenges the world faces today," added Prof Kuepper.
