Russia's Federal Assembly will investigate the scrapping of the maritime delimitation treaty with Norway. This should not be interpreted as an empty threat, Nupi researcher Julie Wilhelmsen states.

Climate change: One year of warm currents fundamentally changed Spitsbergen’s sea ice coverage

OPINION: When meteorologists report fine weather on Svalbard, it's the air temperature they talk about. But when it comes to global warming, ocean temperature is the big joker.

Seabed methane release follows the rhythm of the tides

SHARE YOUR SCIENCE: Methane is constantly being released from the seabed into the ocean. A recent study in the Arctic Ocean shows that this release follows pressure changes in the sea level related to daily lunar cycles.

The deep blue Arctic Ocean: A scientific diver's tales of life under water

"I love the ocean, I love the Arctic, I love the knowledge of this stunningly beautiful world I have gathered over the years. This is why I wanted to become a marine biologist."

Do you think we know whom we share this planet with? Then you are mistaken.

Hot topics from the cold

More than 75% of the Earth’s surface is occupied by cold environments. Cold environments are hot spots for the organisms living there.

Care for you core!

We have recently drilled 34 ice cores from the sea ice. We expected to find very little life inside the ice, but we were proven wrong.

Do the animals at the bottom of the ocean know it’s dark season?

Do the animals at the bottom of the ocean, that might never have been exposed to sunlight, notice the dark season as we do? It seems logical to assume that the polar night should go by completely unnoticed by them. But it doesn’t.

In the Arctic Ocean and on the shoulders of giants

Blowing in the Arctic wind

Imaging driving with an open cabriolet car at 90km/h inside a gigantic freezer box at -25 degrees C with all windows opens. This does not sound comfortable and most people would not be part of such a situation voluntarily. But this has been the conditions we had been facing for the first days of our Q4 expedition.

The Arctic Ocean is not an important shipping route – yet

OPINION: Ten ships navigated the Northeast Passage last year, while 18,000 transited the Suez Canal. It will be a long time before the Northern Sea Route becomes an important navigational route, but the development must be followed closely.

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.

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.

Tiny polar creature must deal with competition

Calinoid copepods are tiny creatures of vital importance to the northern polar marine ecosystem. If temperatures in the Arctic Ocean rise, the balance between the species may change.
