British project launches to study the world’s most dangerous glacier
canada goose clearance sale “For global sea canada goose outlet official level change in the next century, canada goose jacket outlet store this Thwaites glacier is almost the entire story,” said David Holland, a geoscientist at New York University, who will pair with British Antarctic Survey canada goose outlet nyc researcher Keith Nicholls to lead one of the six scientific field missions. canada goose clearance sale
canada goose coats Thwaites is wide and deep canada goose outlet mississauga and flows out of the heart of West Antarctica, a marine ice sheet that could contribute about 10 feet of global sea level rise. Thwaites is losing ice rapidly, with its 50 billion tons per year currently driving 4 percent of global sea level rise, and sits perched in 2,600 foot deep waters atop a seafloor “bump” that scientists fear is the last thing holding it in place. canada goose coats
canada goose coats on sale Past the bump, the ocean gets deeper still, and if Thwaites retreats down that hill, canada goose outlet uk sale there could be no stopping it. Its contribution to sea level rise could increase dramatically, bumping up the current global rate of 3.2 millimeters per year. canada goose coats on sale
Canada Goose Online “The thinking is that if it goes inland, there are no bumps to hold it, and it will go faster and faster and retreat effectively to the South Pole,” Holland said. Canada Goose Online
canada canada goose outlet black friday sale goose black friday sale Thwaites is a key part of the reason that recent computer modeling studies have predicted that the Antarctic could double the previously projected rate of sea level rise during this canada goose parka uk century. But it is located in an extremely remote area, and the critical region that will determine how fast the canada goose outlet uk glacier retreats the “grounding line” where ocean, ice and bedrock meet at canada goose outlet new york 2,600 foot depths remains little studied. canada goose black friday sale
canadian canada goose outlet locations in toronto goose jacket It’s among the most difficult places on Earth for humans to explore. National Science Foundation (NSF) and the British Natural Environment Research Council (NERC) will deployto Thwaites in the next several years will be canada goose outlet price backed by two computer modeling projects to process data from those missions and calculate what it means for the world’s coastlines. canadian goose jacket
uk canada goose One canada goose outlet in chicago celebrity will be participating: “Boaty McBoatface,” an underwater research vehicle whose name stems from a online vote in Britain. After NERC gently ignored a popular vote and declined to award that name to a new icebreaker, as the online voters wanted, it went to the research vehicle. uk canada goose
canada goose The cost: $25 million for the research itself and possibly $25 million more for logistical support, which canada goose clothing uk will mean transporting canada goose outlet uk fake scientists to the remote Thwaites via planes, icebreakers, tractors, helicopters and other vehicles, and supporting them in the harsh environment. About 100 scientists are involved in the project in various capacities.”Thwaites is exactly in the worst position in West Antarctica,” said Sridhar Anandakrishnan, a Penn State canada goose outlet seattle geoscientist who will lead a Thwaites mission with Andy Smith of the British Antarctic Survey. “It’s just about as far from anywhere as you can get. It makes it really, really important Canada Goose Outlet to have this kind of integrated push of logistics.” canada goose
canada goose uk shop Anandakrishnan’s team will be doing seismic surveys detonating small explosives within Thwaites to measure the echo as the sound waves from the blastbounce off the seabed beneath the thick ice and return. That will allow for measurement of what kind of substance Thwaites is flowing over, whose makeupcould determinethe glacier’srate of retreat. canada goose uk shop
Canada Goose Coats On Sale “If you have a soft bed, the bed deforms readily, the ice at the grounding line melts because of the ocean, it gets steep there, it wants to accelerate, and it wants to pull in ice from the interior,” Anandakrishnan said. “And the bed says, ‘Yep, that’s fine, here you go.’ ” Canada Goose Coats On Sale
Canada Goose Outlet Holland’s project, meanwhile, will involve setting up atop the ice over the grounding line, drilling down as much as 2,600 feet, and releasing undersea vehicles and installing measuring devices in the ocean below in pitch blackand at extreme pressures. Canada Goose Outlet
buy canada canada goose outlet florida goose jacket cheap “We are going to drill at the grounding zone, put in a remotely operated vehicle and explore that canada goose outlet real area that’s never before been seen,” Holland said. “That’s very exciting.” buy canada goose jacket cheap

cheap canada goose uk The entire Amundsen canada goose outlet miami Sea region, where Thwaites lies, has been losing ice rapidly, and scientists think this is canada goose stockists uk being caused by warm ocean waters, which are climbing onto continental shelves from farther offshore and melting the glaciers from below. cheap canada goose uk
Canada Goose sale In the Antarctic, a canada goose outlet london uk cold surface layer of ocean water actually lies above a warmer, deeper layer. While not much above freezing, the salty waters, acting at high pressures because of the depths involved, can rapidly melt ice. Canada Goose sale
uk canada goose outlet Moreover, recent research suggests that in the Amundsen Sea region, the ongoing losses of ice from Thwaites and other glaciers are freshening the surface ocean,blockinga process in which surface waters sink and form so called canada goose outlet store montreal Antarctic Bottom Water and, along the way, inhibit warm offshore waters from melting Thwaites and other glaciers. uk canada goose outlet
Canada Goose Jackets This could be a “feedback” process in which more ice loss from Thwaites leads, via the ocean, to more ice loss canada goose outlet michigan from Thwaites. Canada Goose Jackets
canada goose uk black friday The thickness of the glacier is another concern. As Thwaites canada goose uk site retreats backward into a deep ocean canyon even deeper than the current 2,600 feet the entire glacier front will get thicker and thicker, canada goose factory outlet and more than300 feet of ice could eventually protrude above sea level. But it’s not clear whether ice cliffs this tall are able to be sustained above the water level, meaning that the cliffs could continually collapse, driving faster retreat. canada goose uk black friday
canada goose uk outlet The Thwaites mission is designed to gather large volumes of data on all of these processes that, once fed into computer models, will give more accurate projections of the rate and volume of sea level rise during the current century and help determine whether Thwaites will indeed play an outsize role canada goose uk outlet.
