In a 2 degrees Celsius world, the Arctic Ocean would be ice-free roughly one-in-four years, whereas if warming does not exceed 1.5 degrees Celsius, the odds drop to one-in-40, the researchers concluded. "I didn't expect to find that half-a-degree Celsius would make a big difference, but it really does," ... Arctic
Using different climate model simulations and techniques, the studies both show that adhering to the aspirational target of 1.5 degrees Celsius under the Paris Agreement would have a far better chance of keeping the Arctic Ocean ice-covered year-round. Sure, there might be a year or two where ... pollution Arctic
Sunday, March 25, 2018, 16:02 - Winter sea ice on the Arctic Ocean covered the second smallest area on record this year, part of a thaw that is opening the region to shipping and oil exploration and may be disrupting weather far to the south, scientists said on Friday. The extent of floating ice likely reached an ...
In 1845, Franklin sailed from England with two ships, the HMS Erebus and HMS Terror, in an attempt to find a navigable route to the Pacific along the coast of North America through the Arctic Ocean. Aside: Who in his right mind names his ship the Terror? It turns out it was a fitting moniker. "Franklin's Lost ...

Every year, the sea ice cover blanketing the Arctic Ocean and surrounding seas thickens and expands during the fall and winter, reaching its maximum yearly extent sometime between late February and early April. The ice then thins and shrinks during the spring and summer until it reaches its annual ...

As a result, the gas can be transported thousands of kilometres across the Arctic Ocean and released in a completely different region months later. This phenomenon is the subject of an article by researchers from the Alfred Wegener Institute, published in the current issue of the online journal Scientific ...
It's often said that on this warming planet, nowhere is changing faster than the Arctic. But this winter is providing stunning new evidence of a region in extraordinary, worrying flux. It's also a hint of the future to come: an Arctic Ocean that's not permanently frozen and all the disastrous consequences that come ...
"From a military, geographic, and scientific perspective, the Arctic Ocean is truly unique, and remains one of the most challenging ocean environments on earth," Pitts said. The unique acoustic undersea environment is further compounded by the presence of a contoured, reflective ice canopy when ...
In late February, a large portion of the Arctic Ocean near the North Pole experienced an alarming string of extremely warm winter days, with the surface temperature exceeding 25 degrees Fahrenheit above normal. These conditions capped nearly three months of unusually warm weather in a region that ...
Both submarines, as well the U.K. Royal Navy submarine HMS Trenchant, are participating in the biennial exercise in the Arctic to train and validate the warfighting capabilities of submarines in extreme cold-water conditions. “From a military, geographic, and scientific perspective, the Arctic Ocean is truly ...
It's one of the harshest environments on Earth. But the Arctic is also of growing strategic importance - where the U.S. is in a race with the Russians to dominate the ice and sea militarily and exploit it scientifically. To that end, the Navy's ICEX submarine exercise regularly held in the icy Arctic Ocean since the ...

1, 1947, the diesel submarine USS Boarfish with Arctic Submarine Laboratory's founder Dr. Waldo Lyon onboard serving as an Ice Pilot, conducted the first under-ice transit of an ice floe in the Chukchi Sea.

Three of us -- me, my wife, Lisa, and my brother, Jerry -- were traveling from northwest Alaska's De Long Mountains to the Arctic Ocean, negotiating a route from the south side of the mountains to the North Slope, down the Kokolik River. If you look at the area on Google Earth, you'll see a vast treeless ...
He is one of the few scientists to have witnessed the Arctic Ocean move from a period of relative stability toward ecological upheaval under changing climate conditions and report back on the region's changing story. Last week, in recognition of his lifetime contribution to Arctic research, Carmack received ...
ANCHORAGE, ALASKA – Some polar bears in the Arctic are shedding pounds during the time they should be beefing up, a new study shows. It's the climate change diet and scientists say it's not good. They blame global warming for the dwindling ice cover on the Arctic Ocean that bears need for hunting ...
It also stressed China's support to formulate a legally binding international agreement on the management of fisheries in the high seas portion of the Arctic Ocean and to the establishment of an Arctic fisheries management organization or making other institutional arrangements based on the UNCLOS.
In December, the EU, the US, Russia, China, Canada, Japan, Iceland, Denmark and South Korea – all with interests in the Arctic – agreed an official moratorium on commercial fishing across an area of 2.8 million sq km in Arctic Ocean waters. While there is as yet no commercial fishing taking place at this ...
Our goal was to fingerprint the source of methane in the Arctic Ocean to determine if ancient methane was being liberated from the seafloor and if it survives to be emitted to the atmosphere,” says Sparrow, who conducted the study as part of her doctoral research at the University of Rochester. Sparrow, her ...
As the world warms, methane trapped in ice beneath the Arctic Ocean is released. Methane is such a powerful greenhouse contributor that if the unfrozen gas reaches the atmosphere, the effects would be catastrophic. Thankfully, the methane in at least one location is being consumed by microorganisms ...
Climate change is transforming the Arctic Ocean in ways that could permanently alter the food chain and impact ocean species, according to a new study. The study, published in the journal Science Advances, looked at the concentration of the chemical element radium-228 in the central Arctic Ocean and ...
The Arctic melt pond shown in the photograph above is a sign of much greater changes afoot in the frozen north. Over the past decade, the amount of material in the central Arctic Ocean that comes from ice shelves – such as nutrients, carbon, trace metals, and radium – has greatly increased. This increase ...
Friday, January 12, 2018, 2:45 PM - As climate change accelerates, the Arctic Ocean has experienced tremendous upheaval over the past decade: Warm water streaming into the region north of Scandinavia and Russia has led to an “atlantification” of the ocean; sea ice cover has experienced the greatest sustained rate of ...
Having lived in Alaska for 22 years and having been able to travel throughout the state — to Prudhoe Bay, to Barrow on the Arctic Ocean and many points in between — I have been in ANWR. The footprint of Prudhoe Bay, which is to the east of ANWR, for example, is only 558 square miles. The argument ...
So normally in the middle of the summer, when you have 24 hours of daylight, the Arctic ocean has been covered in ice, so 24 hours a day, most of the Arctic ocean was acting like a big mirror, reflecting solar energy back into space, like it never occurred. Now in the summer about half the Arctic ocean is ...
As climate change accelerates, the Arctic Ocean has experienced tremendous upheaval over the past decade: Warm water streaming into the region north of Scandinavia and Russia has led to an “atlantification” of the ocean; sea ice cover has experienced the greatest sustained rate of decline on record; ...
But the scientists weren't just calling for a moratorium on fishing in the Central Arctic Ocean. They wanted data, lots of data that would inform governments, fisheries and other stakeholders about the health and resources of the area that for centuries had remained a “terra incognita” for commercial fisheries.
Date: January 8, 2018; Source: Helmholtz Centre for Ocean Research Kiel (GEOMAR); Summary: For years, methane emissions from the seabed have been observed in the Arctic Ocean off Spitsbergen. The assumption that the warming of seawater by climate change is responsible for the release of methane, has not been ...
Researchers working near the middle of the Arctic Ocean have found that levels of radium-228 have shot up rapidly over the last decade, as vanishing ice leads to more sediment getting swept up into the water. Not only does it show how far-reaching and complicated the effects of global warming can be, ...
Trump's push to open up the Arctic Ocean to offshore drilling is irresponsible and dangerous. The remote, harsh Arctic waters have been largely off limits to oil development for good reason. An oil spill would be impossible to clean up and would imperil endangered polar bears and bowhead whales.
Kipp led efforts to measure radium at 69 locations from the western edge of the Arctic Ocean to the Pole on a two-month voyage aboard the icebreaker Healy in the summer of 2015.
