Please be respectful of copyright. It has been said that when he returned, he reported exactly what took place during this exploration. Its European Space Agency equivalent, CryoSat-2, collected similar data starting in 2010 but over a broader area and with less precision. Satellite images from Aug. 30, 2017 through Dec. 2, 2017 show the rarely-seen opening in the late Southern Hemisphere winter sea ice. Investigators said they found .223 caliber shell casings at the scene, the kind of bullets used in an AR-15 or other style rifle. 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. The fluorocarbon-ozone theory was a theory. The lakes grow and shrink beneath the ice. First Steps to Recovery. Crutzen, P. J. Q. J. R. Meteorol. It would balloon in size over the weeks to come, reaching 31,000 square miles (roughly the size of Ireland) by late October before it merged with the open ocean as Antarctic sea ice retreated with the onset of summer. Past the South Pole is the great unknown. You could fly one of our LC130 into this thing. At 12:10 a.m. Tuesday, one pilots crash pad became a crime scene. Lett. When you purchase through links on our site, we may earn an affiliate commission. A National Geographic team has made the first ascent of the remote Mount Michael, looking for a lava lake in the volcanos crater. As the scientists analyze that mud, it may yield more diatoms. The Commonwealth has been found guilty of two charges over the 2016 death of a helicopter pilot in Antarctica. Those floating shelves provide a buttress; they are holding back a very big amount of ice, says Craig Stevens, an oceanographer from the National Institute of Water and Atmospheric Research in New Zealand, who participated in the expedition. At 12:10 a.m. Tuesday, one pilots crash pad became a crime scene. Changes in the ice surface of the Amery Ice Shelf in Antarctica reveal the rapid draining of a lake deep below in 2019. It seems the animals attached to the boulder drifted there as microscopic larvae, and then grew into their adult forms: life is everywhere and the environment selects the species that eventually thrive., A future stage will be to determine if the animals are similar to those in the open ocean, or if they had evolved to live where they are now, Priscu said in an email. But once it does, we have the knowledge and the technology to do something about it. I started at the present and was going to work back, and my colleagues really didnt believe that this was significant. To obtain Global sea levels would rise by 10 feet if West Antarctica lost these crucial stabilizers and spilled its ice into the ocean. 58 (WMO, 2018). We may earn a commission from links on this page. In January of 1956Admiral Byrdled an expedition to the South Pole. By 1984, the stratospheric ozone layer over Halley in October was only about two-thirds as thick as that seen in earlier decades a phenomenon that became known as the Antarctic ozone hole. When is it going to stop?. A student lowered his camera 93 meters into the ground in Antarctica while collecting ice that's estimated to be over two million years old. All rights reserved, See more of the world below Antarctic ice, See what would happen if all the worlds ice melted, Learn about the Maine-size hole in Antarctica. The ice holeknown as a polynya in the parlance of sea ice researcherswas likely caused by a powerful cyclone that spun up in Antarcticas Press, 1984). So, basically, it was more than an order of magnitude greater than we expected. Campbell was supported by the U.S. Department of Defense through the National Defense Science & Engineering Graduate Fellowship program. We need to improve our models so we can study this process, which could have larger-scale climate implications.. I really think that the whole episode of the ozone hole discovery and all the subsequent things that happened, in terms of explaining it, mapping it etc., are a huge success story for the science of understanding the stratosphere. They also found that what was thought to be one lake under the MacAyeal ice stream was actually two. J. C. Farman, B. G. Gardiner and J. D. Shanklin, British Antarctic Survey, Cambridge, UK. Like I said, its pilots. (See what would happen if all the worlds ice melted.). Scientic Assessment of Ozone Depletion: 2018 Report No. Admiral Richard Byrd referred to Antarctica as The Land of Everlasting Mystery and of the North Pole he said: Id like to see that land past the North Pole, it is the Center of the Great Unknown.. Nature, international weekly journal of science. It's thought both types of stationary animals are types of sponges or are related to sponges, but scientists did not expect to find them beneath the ice shelf, in pitch-blackness and hundreds of miles from the coast. Explore a billion-year-old volcanic mystery on Lake Superior, A journey of the senses through Abu Dhabi. "The reason stated because of a air sampling camp in that area. But to their surprise, the camera showed colonies of stationary animals attached to the rock probably sponges and related sea creatures. Thank you for visiting nature.com. The Ross Ice Shelf is considered more stable, at present, than many of West Antarcticas other floating shelvesand this observation could help explain that: if a few inches of sea water periodically freezes onto the bottom of its ice, this could buffer it from thinning more rapidly. For more information, contact Campbell at ethancc@uw.edu and 224-388-0301, Riser at riser@uw.edu and 206-543-1187 or Wilson at earlew@uw.edu. Already, researchers are finding the links between the under-ice lakes and the ocean: In January, a study co-authored by Fricker found that the drainage of one lake on the Amery Ice Shelf in East Antarctica flushed as much as 198 billion gallons (750 billion liters) into the ocean in only three days, Live Science reported at the time. In 1985, Joe Farman, Brian Gardiner and Jonathan Shanklin reported1 unanticipated and large decreases in stratospheric ozone levels over the Antarctic stations of Halley and Faraday. The ICESat satellite used lasers to precisely measure the elevation of Antarctic ice. Total ozone has been measured at the British Antarctic Survey stations, Argentine islands and Halley Bay since 1957. In a statement to WMC, FedEx said: Our thoughts remain focused on the well-being of our team member. Whatever the absolute error of the recent values may be, the annual variation of total ozone at Halley Bay has undergone a dramatic change. We may earn a commission from links on this page. Atmos. 'NASA images show giant hole at North Pole leading to hollow Earth' conspiracy theorists claim. These images reveal NASA is hiding a huge hole leading directly to the centre of the Earth, conspiracy theorists have claimed. As senior study author David Holland of New York Universitys Abu Dhabi Research Institute explained to Earther by phone this week, the presence of the Maud Rise seamountwhich he described as the equivalent of the Himalayas except underwater in a polar oceanpushes the warm, dense, salty water that typically lingers near the seafloor closer to the oceans surface. In January of 1956, Admiral Byrd led yet another expedition to the South Pole. 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. Ex-US Naval officer 'saw entrance to secret alien base in Antarctica' Life discovered in buried Antarctic lake, Extreme Antarctica: Amazing photos of Lake Ellsworth. Cold, dark and alive! What if we could clean them out? 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. Google Scholar. This flow, in turn, can change the currents in the Southern Ocean and potentially affect ocean circulation worldwide. This certainly had more of a military signature rather than an innocent exploration. Welcome to the Hollow Earth Research Society, Admiral Richard Byrd andthe Hollow Earth. CNN Sans & 2016 Cable News Network. It sits in a broad, low bowl that dips thousands of feet below sea levelmaking it vulnerable to deep, warm ocean currents that are already nipping at its outer edges.

My name is Erik Conway. Scientists fear that some of these ice shelves are already weakening. Lett. Discovery Company. PubMed Ex-Navy pilot says he saw UFOs that did things his plane could not do. 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. Pyle, J. What we call the ozone Google Scholar. Admiral Richard Byrdproved not only a great explorer who had enough integrity to lead massive explorations of both poles, but sufficient character to tell the world what the government did not want him to reveal. Concerns were raised, really, in the 1960s and 70s that substances that we were manufacturing, in particular chlorofluorocarbons the CFCs might put chlorine high into the atmosphere where it could then photocatalytically interact with the ozone and destroy ozone. Youve been listening to the Nature PastCast, produced by Charlotte Stoddart and with contributions from Jonathan Shanklin, Richard Stolarski and historian Erik Conway. So, when the British Antarctic Survey paper is published in 1985, a lot of people are rather shocked because during the early 1980s, they werent sure whether there was evidence of depletion and thats because its a difficult question to answer. Their work could shed light on a poorly understood, but ominous episode in Antarcticas recent past. The new year once started in Marchhere's why, Jimmy Carter on the greatest challenges of the 21st century, This ancient Greek warship ruled the Mediterranean, 3 ways Jimmy Carter changed the world for the better, Why evenings can be harder on people with dementia, This disease often goes under-diagnosedunless youre white, The groundbreaking promise of cellular housekeeping. 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. We also may change the frequency you receive our emails from us in order to keep you up to date and give you the best relevant information possible. Ocean measurements were also collected by seals swimming under the sea ice with temporary satellite tags, showing normal water conditions in the years that did not have large polynyas.Dan Costa/University of California, Santa Cruz, This study shows that this polynya is actually caused by a number of factors that all have to line up for it to happen, said co-author Stephen Riser, a UW professor of oceanography.
