Scientists investigate a particular kind of fish that has evolved to survive in the severe arctic climate. However, on a field trip in 2018, they discovered an unusual phenomenon: several of the fish had terrible skin tumors.
Life in the Arctic is harsh. Arctic temperatures are punishing, making life difficult for many animals to survive. Yet lots of insects, including mosquitoes, manage to thrive in the frozen region. So why don't they freeze themselves?
Whales are huge, but they live in an even larger environment—the world's oceans. Researchers use a range of tools to study their whereabouts, including satellite tracking, aerial surveys, sightings and deploying individual hydrophones to listen for their calls.
Rising temperatures are melting the Arctic sea-ice on which polar bears hunt, limiting their access to food. A recent study has found a remote population of polar bears that have adapted to hunt on chunks of glacier ice.
As we know, the Arctic tundra won't be around much longer. Climate change is causing the sea levels to rise, and the ice to melt, which is also, in turn, wiping out the plant and animal species that live there. And unfortunately things aren't much different in Siberia.
Home to polar bears, the midnight sun and the northern lights, a Norwegian archipelago perched high in the Arctic is trying to find a way to profit from its pristine wilderness without ruining it.
These are strange times for the Indigenous Nenets reindeer herders of northern Siberia. In their lands on the shores of the Arctic Ocean, bare tundra is thawing, bushes are sprouting, and willows that a generation ago struggled to reach knee height now grow 3 meters tall, hiding the reindeer. Su ...
At first, it was a simple question: what exactly did oil pollution do to gray seals off the coast of Norway?
With marine heat waves helping to wipe out some of Alaska’s storied salmon runs in recent years, officials have resorted to sending emergency food shipments to affected communities while scientists warn that the industry’s days of traditional harvests may be numbered.
Researchers at the Barcelona Expert Center (BEC) of the Institut de Ciències del Mar (ICM-CSIC) have proved that satellite-derived salinity improves marine circulation prediction in the Arctic, which, as in the rest of the planet, is directly influenced by this and other parameters such as tempe ...
A new study published in Ocean Science conducted by CAGE Ph.D. candidate Knut Ola Dølven and co-authors presents time-series data from two methane seep sites offshore western Svalbard, in the Arctic.
The combined effects of climate change and nutrient availability on Arctic vegetation growth are poorly understood. Archaeological sites in the Arctic could represent unique nutrient hotspots for studying the long-term effect of nutrient enrichment.
Small fish are abundant in the 200-600 m deep Atlantic water layer of the Amundsen Basin, according to a unique hydroacoustic dataset collected by the EFICA Consortium, which revealed a "deep scattering layer" (DSL) consisting of zooplanktion and fish along the MOSAiC expedition's 3170 km long t ...
Canada is known for its varied landscape, ranging from mountains and rolling plains, to rivers, lakes and Arctic tundras. It is therefore unsurprising that a great variety of animals make this region its home.
We may lose up to three meters of coastline in the Arctic every year by 2100 if greenhouse gas emissions are not reduced, according to a study published in the journal Nature Climate Change. The authors also warn about bigger waves due to increasing temperatures, making the coastline very vulner ...
In the last five years, scientists have observed sea animals dying off at an alarming rate in the northern Pacific waters.
Cultural heritage sites are irreplaceable sources of historical information, providing insight into the social, religious, and economic life of our ancestors. They are important markers of identity, and constitute attractions to both locals and visitors, and can thus play an important role in a ...
Ihad dreamed about photographing polar bears for a long time. Some time ago my hobby, wildlife photography, ceased to be just a hobby and turned into a large part of my life.
IT'S EARLY August and the research vessel Barba sails at 80 degrees north along the coastline of Svalbard. The endless Arctic sun lies low on the horizon, the ocean is calm, and the temperate a mild 5 degrees.
As the arctic warms four times faster than the global average, Europe’s only indigenous population is under threat. For centuries, the Sámi people have herded reindeer throughout northern Europe.
An Asian megacity partially locked down because of pollution. Acres of farms in Africa destroyed by extreme weather. Ancient Arctic cultures disappearing with melting ice. This isn’t the future. It’s happening now.
Irina Panyushkina grew up in Siberia, near the Arctic Circle. She was raised on stories of explorers trudging through seas of ice to reach the North Pole.
Thawing Arctic permafrost laden with billions of tonnes of greenhouse gases not only threatens the region's critical infrastructure but life across the planet, according a comprehensive scientific review.
I stepped onto the battlefield of climate change, sidestepping carcass after carcass. In the grass were the remains of Arctic terns, common terns, and roseate terns. Along the boulders, researchers pointed out dead puffin chicks.
The transformation of the rapidly warming Arctic is being accelerated by a wave of thousands of newcomers that are waddling and paddling northwards: beavers.
As the Arctic and the oceans warm due to climate change, understanding how a rapidly changing environment may affect birds making annual journeys between the Arctic and the high seas is vital to international conservation efforts.
As the UN Climate Change Conference (COP 26) called on nations to cooperate on mitigating climate change, nowhere is this call more urgent than in the Arctic region.
The field of pathogens in northern wildlife is ripe for further study, according to some scientists
The ice shelf was cracking up. Surveys showed warm ocean water eroding its underbelly. Satellite imagery revealed long, parallel fissures in the frozen expanse, like scratches from some clawed monster. One fracture grew so big, so fast, scientists took to calling it “the dagger.”
The highest temperature ever recorded in the Arctic, 38C (100F), has been officially confirmed, sounding "alarm bells" over Earth's changing climate.
While a reduction in frozen ocean surface is one of the most widely recognised impacts of Arctic warming, it has also long been anticipated that a warmer Arctic will be a wetter one too, with more intense cycling of water between land, atmosphere and ocean.
The warship HMS Terror lies at the bottom of the Arctic Ocean in the Northwest passage, lost in 1848 after two grueling years stuck in the Arctic ice. Rescue missions launched to recover the ship in 1851 suffered the same fate, crushed under the year-round ice that encased Northern Canada and th ...
The Arctic Ocean has been warming since the onset of the 20th century, decades earlier than instrument observations would suggest, according to new research.
The reason for the increased attention is that the Arctic is becoming a new stage for some of the most defining issues of our time: climate change, the urgent need for inclusive and sustainable development, and geopolitics.
In one of the planet’s coldest places, 130 km south of Russia’s Arctic coast, scientist Sergey Zimov can find no sign of permafrost as global warming permeates Siberia’s soil.
The disruption from the climate emergency being experienced by marine wildlife reached a new high in the first week of Cop26, when a female walrus was discovered sleeping on a submarine in a naval base in North Holland.
Climate change is disproportionately affecting the polar regions. In a paper published earlier this year, researchers from the Arctic Monitoring and Assessment Programme (AMAP) revealed that in the last just the last 50 years, the Arctic warmed up by nearly three times quicker than the rest of t ...
The annual migration of birds from the Arctic to the Gulf of Mannar Marine Biosphere Reserve, has begun with an enormous flock seen swarming the Manoli Islands inside the park last weekend.
Sweating, headaches, fatigue, dehydration – the ways heat exhaustion affects the human body are well documented. As temperatures inch up year by year we need to change the way we live, creating cooler places that provide refuge from heat.
One way that scientists monitor climate change is through the measure of sea ice extent. Sea ice extent is the area of ice that covers the Arctic Ocean at a given time. Sea ice plays an important role in reflecting sunlight back into space, regulating ocean and air temperature, circulating ocean ...
In a pair of recently published papers, Michael Rawlins, a professor in the University of Massachusetts Amherst's geosciences department and associate director of the Climate System Research Center, has made significant gains in filling out our understanding of the Arctic's carbon cycle—or the w ...
The melting of polar ice is not only shifting the levels of our oceans, it is changing the planet Earth itself. Newly minted Ph.D. Sophie Coulson and her colleagues explained in a recent paper in Geophysical Research Letters that, as glacial ice from Greenland, Antarctica, and the Arctic Islands ...
A massive Russian icebreaker ship clears a path to the North Pole, cutting through the thin ice of the Arctic Ocean. Even in this far-flung region, the impact of climate change can be seen.
Warmer air weakens the vortex, which normally keeps cold air trapped in Arctic, letting it go south. Warming of the Arctic caused by climate change has increased the number of polar vortex outbreaks, when frigid air from the far north bathes other parts of the Northern Hemisphere in killer cold, ...
In June, the Central Arctic Ocean Fisheries Agreement entered into force, bringing to fruition a diplomatic effort that began more than a decade ago.
Like many people, I will remember this summer in shades of gray and red. As snapshots of a dull orange sun circulated social media, "zombie fires" rose from the Russian permafrost, entire towns were wiped off the map and Southern Europe became a scene of the apocalypse.Satellites tracked enormou ...
Climate change is driving periods of unusually high temperature across large swaths of the planet. These heat waves are especially detrimental in the Arctic, where they can push surface temperatures in regions of significant permafrost past the melting point of ice lenses.
As the North Pole, the Arctic Ocean, and the surrounding Arctic land warm rapidly, scientists are racing to understand the warming's effects on Arctic ecosystems. With shrinking sea ice, more light reaches the surface of the Arctic Ocean. Some have predicted that this will lead to more plankton, ...
Natural silence -- the kind when you hear nothing but the sound of nature around you -- is becoming increasingly scarce. The rumblings of man-made noise can be heard even in the remote corners of national parks and deep in the Arctic Ocean.
Known as 'forever' chemicals due to the fact they do not break down in the environment, poly- and perfluoroalkyl substances (PFAS) are used in a wide range of products and processes from fire proofing to stain resistant surfaces.
