Food and health security in the Norwegian–Finnish–Russian border region

In many Arctic regions, hazardous substances from local or (mostly) far-away sources are found at levels that may threaten the health of both humans and the environment.

Fat matters when sea ice melts: polar bears, pollutants and sea ice decline

While most of us have declared war on fat, the layer of fat beneath our skin is vital. Fat cells store energy in the form of lipids. In addition to being the body’s largest energy supplier, these cells secrete hormones that control whether we feel hungry. Arctic animals also need fat as insulation.

Looking for answers from indigenous peoples on the tundra

What happens when indigenous pepoles are exposed to globalisation and assimilation? It is possible for ttem to maintain their cultural heritage and continue with their traditional way of life? Zoia Vylka Ravna went to the Nenets on the Russian tundra in search of answers.

Searching for environmental contaminants using UFOs

Environmental contaminants can travel with the wind from the equator to the Arctic, and the longer such contaminants survive in the environment, the greater their potential to cause unwanted effects on people, animals, and nature. Scientists from NILU have recently criss-crossed Norway, using “UFOs” to search for airborne organic contaminants.

Polar cod: Vulnerable to oil spills

The arctic cod is common throughout the Arctic and is a major source of food for seals, whales and seabirds. Recent research shows that even small amounts of oil can affect the growth of this vital fish, and lead to deformities and death.

SOS from the Arctic

What happens if a ship loaded with toxic chemicals founders in the Arctic during the dark months of the polar night? What about the crew? And the ecosystem? 

The spread of toxic mercury is affecting the Arctic

The transport of environmental contaminants to the Arctic via water and air is a threat to the environment. Research done at the Fram Centre confirms that in the Arctic, methylmercury moves more effectively through the food chain than in more southerly waters.

Seabird breeding timing at high latitudes

Imagine an Arctic bird cliff in summer, teeming with fledging chicks and predators waiting below. Now fast-forward to a short time later and picture a quiet breeding cliff dusted in snow. What evolutionary adaptations and constraints shape when birds breed in seasonal environments? And when conditions change, will birds breed at the “right” time?

The atmosphere’s role in the rise and fall of the guillemot

What killed the guillemots? In a north Norwegian colony of common guillemots at Hornøya, fewer than one in three birds survived the winter of 1986/87. The obvious cause was a lack of fish, but thanks to the emerging science of climate ecology, we now know that weather patterns may also have played a part.

SEATRACK – Where do seabirds go after the breeding season?

Most seabirds spread over vast areas in the non-breeding season. Until now, these movements have been difficult to study, but in a new programme called SEATRACK, birds are being fitted with tiny logging devices that will give us clues on where they go in winter and what threats they face there.
