Arctic Ocean

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,” said ...

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 natural ...

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 annual ...

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 ...

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 annual maximum of 14.5 ...

The Arctic Ocean is not only ranked the smallest in size (it's 10 times smaller than the Pacific Ocean), it's also the shallowest. The average ocean depth, according to the National Oceanic and Atmospheric Administration, is 2.3 miles (3.7 kilometers), or about 12,100 feet. The Arctic Ocean's average depth, ...

The Arctic Ocean is becoming more accessible for shipping. This February a commercial tanker, the Eduard Toll, made the first crossing of the Northern Sea Route in winter. The development of ice-strengthened hull technology is a major factor enabling winter Arctic shipping. The Arctic Ocean is becoming ...

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. In 1958, the nuclear-powered USS Nautilus made the first crossing of the Arctic Ocean beneath the ...

“The Arctic Ocean is fundamentally different now … [it's] a new Arctic Ocean,” he said. The first panel, titled “Sustainable Development Goals in an Arctic Setting,” was sponsored by the Tufts Institute of the Environment and moderated by Bill Moomaw, professor emeritus at The Fletcher School. The panel ...

Scientists say it's a clear sign of “Atlantification,” a sea change now underway as warm Atlantic waters muscle their way into the Arctic Ocean. “This area used to be polar-influenced, cold water,” says Geir Wing Gabrielsen, a scientist with the Norwegian Polar Institute and a coauthor of the new study. “Now it ...

"To the north, this would mean a connection to the Arctic Ocean, and to the south, a connection to the European rail network via the Helsinki-Tallinn tunnel and Rail Baltica. The Arctic Ocean Railway should therefore be seen as part of the global transport system. Curbing climate change also requires ...

When Brynn Devine and Laura Wheeland headed up to the Canadian Arctic for some routine underwater ecosystem surveying, they didn't know what they were going to find. Hailing from the Memorial University of Newfoundland, the researchers were working with the Arctic Fishery Alliance to deploy ...

Ice Camp Skate is seen during camp build during Ice Exercise (ICEX) 2018. ICEX 2018 is a five-week exercise that allows the Navy to assess its operational readiness in the Arctic, increase experience in the region, advance understanding of the Arctic environment, and continue to develop relationships ...

The US Navy's Commander, Submarine Forces (COMSUBFOR) has officially begun this year's Ice Exercise (ICEX) in the Arctic Ocean. ICEX 2018 will see participation from three nations' naval services, three submarines and more than 100 personnel during its five weeks of operations. The US Navy ships ...

MOSCOW – Shipping company Mitsui O.S.K. Lines Ltd. put an ice-breaking tanker into service in the Arctic Ocean on Thursday to transport liquefied natural gas from a Russian plant to Europe, becoming the first Japanese firm to own and operate such a vessel. The Vladimir Rusanov will deliver LNG from a ...
