Researchers discover missing link in the evolution of complex cells

Researchers have discovered a new microbe in the Mid-Atlantic Ridge between Greenland and Norway, which represents a missing link in the evolution of complex life.

New sideswimmer discovered

A new species of sideswimmers (amphipod) has been found on the continental slope off northern Norway. The new species is approximately 1 cm long, and appears to prefer water temperatures below 0 °C and depths of 1,000-2,600 metres. In total, 50 specimens of the new species were found.

Sea creatures are threatened by our medicines

Medication ingested by humans is taken up by algae and sea creatures. Entire ecosystems can be affected, according to a Swedish researcher.

A ship loaded with copepods

The sweet smell of plankton envelopes researchers on deck as they haul up buckets of copepods, shrimp, algae and fish. Spring has come to the Labrador Sea. The marine science gold rush is in full swing.

Soft sea slugs pack a hard punch

Sea slugs may sound like they're soft and squishy, but they have poisonous tentacles and eat nearly everything they come across, including each others' eggs. These delicate and often brightly coloured animals are ferocious predators.

Hitchhiking with ocean currents

Marine animals living on Arctic ice seem destined for a catastrophe if all the summer ice melts. But a tiny krill can survive by hitchhiking north with ocean currents.

Arctic species will survive less ice

Some of the species in the Arctic have adapted to minimal ice cover in summer. The scientists call their hypothesis the “Nemo hypothesis”.

Mapping marine life before oil drilling starts

Foul-smelling bubbles rise from the floor of the Barents Sea. Living organisms in these depths are being studied before the oil and gas industry starts drilling operations.

Waking plankton from hibernation

They are the motor of the ecosystem in the oceans of the high North. But we don’t know much about where plankton are during the sunless winters or how they waken in spring.

World's toughest organisms live in northern seas

If you thought polar explorers were rugged outdoorsmen, then you haven’t met the small organisms that live on the seabed off Svalbard.
