The ice holeknown as a polynya in the parlance of sea ice researcherswas likely caused by a powerful cyclone that spun up in Antarcticas A UFO whistleblower claims he saw the entrance to a top secret alien base hidden deep in the Antarctic. The two plus signs show the location of oceanographic robots that were trapped in a spinning column of water above an underwater mountain known as Maud Rise.AMSR2-ASI/University of Bremen. The hole in the sea ice offshore of the Antarctic coast as seen by a NASA satellite on Sept. 25, 2017. "The reason stated because of a air sampling camp in that area. In the new study, Siegfried and Fricker combined data from ICESat, CryoSat-2 and ICESat-2 to trace changes in the subglacial lake system from October 2003 to July 2020. In February of 1947, Rear Admiral Richard Byrd was in charge of a gigantic procedure in the Arctic that was called Operation Highjump. For out-of-this-world news, sign up for the Spaced Out newsletter. ISSN 1476-4687 (online) A hole the size of Maine has opened in the wintertime sea ice surrounding Antarctica. Police said the pilot, whose identity has not been released, was rushed to Regional One in non-critical condition, hit in the back near his right shoulder. Your effort and contribution in providing this feedback is much In the video the Navy Seal (aka Spartan 1) described the launch of his mission from an aircraft carrier voyaging near West Antarcticas Ross Sea. He was taken by helicopter to McMurdo station, the largest U.S. base in Antarctica, and then taken by ground transport to the structures location. One of the tasks that I had when I first joined the Survey was to process the missing data. NASA said the hole is large enough to have held 14 billion tons of ice -- the majority of which has melted during the last three years.

It's asking people to spot the giraffe hidden among the toy animals, 'I'm a model in my 60s I embrace grey hair and flaunt my body in bikinis', Kathy Jacobs, 60, is in the best shape of her life and she's not shy of posing in a bikini. I Saw Jonathan Frakes Giving Patrick Stewart a Noogie, The 2023 Complete Python Certification Bootcamp Bundle. When we were working up to publishing our paper, concerns had been expressed that these CFCs might destroy the ozone layer, that exhaust gases from Concorde might destroy the ozone layer, and the general thoughts were that any destruction would probably take place at high altitude in the tropics. The 2021 Antarctic ozone hole reached its maximum area on Oct. 7 and ranks 13th largest since 1979. Once this water reaches the surface that carbon could be released. What we discovered at our Antarctic station was quite curious. I was with NASA for 35 years, and I had just come off of a stint as a low-level manager and was just getting back into doing some real science, and we had people who had been taking satellite data of ozone. Campbell joined the UW as a graduate student in 2016 to better understand this mysterious phenomenon. Warmer, saltier water from the depths gets churned up to the surface, where air chills it and makes it denser than the water below. You had to learn how to find the right 9 track tape in a room full of tapes, and its really ironic to look at it today because the satellite was taking about 5 GB of data per year and at that time, when you said that, people were overwhelmingly impressed and now I think a lot of people probably run that through their smartphone every month. Google Scholar. Heres why each season begins twice. This water system was largely invisible until the advent of NASA's ICESat mission in 2003. Its a huge area, but we have a tiny widow into it, Griffiths said. Observations show that the recent polynyas opened from a combination of factors one being the unusual ocean conditions, and the other being a series of very intense storms that swirled over the Weddell Sea with almost hurricane-force winds.. As Heuz put it, everythings connected.. This means that we may include adverts from us and third parties based on our knowledge of you. Solomon, S., Mount, G. H., Sanders, R. W. & Schmeltekopf, A. L. J. Geophys. The fluorocarbon-ozone theory was a theory. All of a sudden, you look at it differently wow, we really can affect the planet as a whole.

But the question of how these animals get food will have to wait until another scientific expedition can visit the spot, perhaps equipped with a remotely operated underwater vehicle that can recover samples of the animals. Many scientists told me that, in fact, they trusted the British Antarctic Survey people. Global sea levels would rise by 10 feet if West Antarctica lost these crucial stabilizers and spilled its ice into the ocean. Investigators said they found .223 caliber shell casings at the scene, the kind of bullets used in an AR-15 or other style rifle. In 1925 there was a singular man on a mission to explore desolate lands rarely seen by humans to that time Admiral Richard Byrd. Who created it? Torge Martin, a meteorologist and climate modeler at the Helmholtz Centre for Ocean Research in Kiel, Germany, told Earther via email that the studys authors make a valuable contribution to explaining the occurrence of the polynya, and they are correct in arguing that the atmospheric side has been less studied in the past., This is because the preconditioning in the ocean is essential, Martin wrote. The lakes beneath the Mercer and Whillans ice stream boundary are currently undergoing their third period of drainage in 17 years. The geologists used hot-water equipment to drill the borehole through more than half a mile of the ice shelf, on the southern edge of Antarctica's Weddell Sea. In that region, an underwater mountain known as Maud Rise forces dense seawater around it and leaves a spinning vortex above. Never was a problem. Atmos. Changes in the ice surface of the Amery Ice Shelf in Antarctica reveal the rapid draining of a lake deep below in 2019. The Ross Ice Shelf has come and gone probably many times in the last million years, says Scherer. Visit our corporate site (opens in new tab). Unauthorized use is prohibited. And yeah, with nice coloured graphics it hits you in the face. A vast amount of aquatic life has its beginnings. If a big storm rolls through and clears away the overlying sea ice, it can then cause this warm water to mix with the cooler, fresher water floating atop the Lazarev sea. Large losses of total ozone in Antarctica. The site of the polynyadirectly above an enormous undersea mountain known as the Maud Risemade it especially intriguing, as similar giant polynyas had been spotted in the same location in satellite imagery from the 1970s. Admiral Richard E. Byrd Encounter With A Lost Civilization in "Talk among the flight crews was that there is a UFO base at South Pole and some of the crew heard talk from some of the scientists working with and interacting with the scientists at that air sampling camp/large ice hole.". Photograph by Herbert G. Ponting, Nat Geo Image Collection, One of Earth's loneliest volcanoes holds an extraordinary secret. 4, 108144 (R. Soc. A. et al. It is not clear to me to this day who coined the term ozone hole and when and where it was done. Former Navy fighter pilot Ryan Graves tells CNN's Alisyn Camerota about his unit's experiences with UFOs and explains the problems they can pose for military and commercial aviation. A legend among those in the know was that Adolph Hitler did not die due to a suicide in 1945, but fled to Argentina, to an SS base carved under the ice in New Swabia during the very early 1950s, where he resumed his passion as a painter. In January 2015, UFO researcher Linda Moulton-Howe (editor of the earthfiles.com website) So said the great explorer, Admiral Richard Byrd. The retired petty officer, 59, claimed to have been seen UFOs, aliens and a giant hole in the ice as he flew through a "no fly zone" in Antartica. This particular spot far from the Antarctic coast often has small openings and has seen large polynyas before. But as the camera passed through the bottom of the hole, it showed the underside of the ice adorned with a glittering layer of flat ice crystalslike a jumble of snowflakesevidence that in this particular place, sea water is actually freezing onto the base of the ice instead of melting it. Lett. Tom Metcalfe writes about science and space for NBC News. The new study used observations from the Southern Ocean Carbon and Climate Observations and Modeling project, or SOCCOM, which puts out instruments that drift with the currents to monitor Antarctic conditions. Ex-US Naval officer 'saw entrance to secret alien base in Antarctica' The Montreal Protocol, as its initially written, was a 50% reduction in production of chlorofluorocarbons it was not a ban. So, I eventually worked up all the missing years and was able to show it was systematic and if youve got something systematic, there has to be something real going on. "ICESat-2 is like putting on your glasses after using ICESat: The data are such high precision that we can really start to map out the lake boundaries on the surface," Siegfried said. Nature 557, 413417 (2018). She lives right Whats going through my mind? Strahan and her colleague Anne Douglass published one of the first studies in 2018 confirming that atmospheric chlorine levels are falling in step with reduced ozone depletion over Antarctica proof that the Montreal Protocol is working.. Atmos. 1). Or by navigating to the user icon in the top right. Cline Heuz, a physical oceanographer at the University of Gothenburg, Sweden, told Earther in a phone interview that other recent research has shown 2017 to be quite an intense year in the Southern Ocean with respect to storm activity. While Heuz said that the new studys findings make sense, shes keen to learn more about the role that the ocean plays, which is why she recently had a student trek out and deploy an autonomous profiler to measure temperature and salinity in the Maud Rise area. The winter ice on the Something went wrong, please try again later. Geologists taking sediment cores from the seafloor beneath the giant Filchner-Ronne Ice Shelf on the southern edge of Antarcticas Weddell Sea discovered what biologists believe are types of sponge. Causes and Effects of Changes in Stratospheric Ozone: Update 1983 (Natl Acad. The ozone hole actually still appears every year, and it has completely disappeared from public conversation. So, after the discovery of the 1985 ozone hole, there was already scheduled a set of negotiations over chlorofluorocarbons to reduce, but not ban, the production of chlorofluorocarbons, and what the discovery of the ozone hole does is demonstrate that there really is a problem and probably helped accelerate the negotiations that were already ongoing. 21, 11911194 (1994). The unexpected discovery of a hole in the atmospheric ozone layer over the Antarctic revolutionized science and helped to establish one of the most successful Eyring, V. et al. Nature (Nature) In 2007, Scripps Institution of Oceanography glaciologist Helen Amanda Fricker connected the elevation changes measured by ICESat to the dynamics of the lakes deep beneath the ice surface. Byrd was an heroic figure, lauded worldwide as an American pilot, polar explorer, and organizer of polar logistics. Frieler, K. et al. Animal life was not what scientists were expecting to find in the pitch-black seawater beneath almost half a mile of floating Antarctic ice, but it seems to have found a way with the discovery of sea creatures living in the extreme environment.

Reed Scherer made this discovery back in 1998 while studying mud that had been plucked from beneath the West Antarctic Ice Sheet, through another borehole, 100 miles inland from the back edge of the ice shelf. Those studies provided only brief glimpses of how deep, warm water circulates under the ice shelf, covering a few hours or days. One day in December, a cylinder dripping with gray gleaming mud was hoisted out of the borehole, into the bright summer suna core plucked from the sea floor, 2,400 feet beneath the drill site. Key points: David Wood died of hypothermia after falling into a crevasse during a routine fuel drop Both the Commonwealth Environment Department and his employer were charged over the death This thinning of the ozone layer over Antarctica came to be known as the ozone hole. In 1977, researchers drilled through the ice shelf 300 miles in from its seaward edge (about 80 miles inland from the current holes), and in 2015 a team drilled through the back corner of the ice shelf, 500 miles in from its seaward edge. Chem. Its messed up right here, right now in Memphis. Scientists have peered into one of the least-explored swaths of ocean on Earth, a vast region located off the coast of West Antarctica. At 3:29 p.m. on November 28, 1929, Byrd, the pilot Bernt Balchen, and two others took off from Little America in the Floyd Bennett, headed for the South Pole. They focused on three areas with good satellite coverage and known active lakes: the boundary between the Mercer and Whillans ice streams in West Antarctica; the lower MacAyeal Ice Stream, also in West Antarctica; and the upper Academy Glacier in East Antarctica.
