DNA analyses reveal secrets about the Pacific oyster

Is oyster larvae drift across the Skagerrak the cause of wild oysters great increase? New DNA analyses provide insight into the origin of the first wild Norwegian sea oyster populations.

Ancient living soil microbes discovered over two kilometres beneath the seafloor

A new study has drilled deeper into the seabed than ever before, and discovered a thriving community of ancient soil microbes, tens of millions of years old

Scientists rediscover extinct sea snakes

A team of scientists from Australia and Denmark have rediscovered two species of sea snakes that were though to have been extinct since 2001.

Killer whales and walruses more closely related to wolves than each other

New study shows how some animals ended up looking very similar yet share almost none of the same genetic mutations.

Red listed species on Svalbard

Red List assessment has been conducted for five groups of species on Svalbard. Overall, 270 species of vascular plants, springtails, freshwater fish, birds and mammals were evaluated. Of these, 71 species were red listed, of which 47 are considered to be threatened.

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.

Blue mussels à la Svalbard on the menu?

Back when the Vikings ruled, blue mussels had a natural habitat in Svalbard. They disappeared when the climate cooled, but today blue mussels have re-established themselves at 78 degrees North. The Svalbard blue mussel is thus a clear and present climate indicator of a warming Arctic.

An acidic ocean may mean less fish

Calanus makes up about 90 percent of the bottom of the food chain in northern oceans, and is eaten by fish and baleen whales alike, but as the ocean becomes more acidic, populations may decrease dramatically.

Spying on seals with videocams and sensors

Researchers are equipping seals with cameras and sensors to find out exactly what they do down in the deep blue sea.

The Greenland shark: an overlooked creature

The Greenland shark is a mythicised and unpopular animal, perhaps due to a lack of knowledge. Now a research team has spent several weeks with some of Disko Bay’s Greenland sharks, where they performed risky experiments to find out more about the shark.
