The ice holeknown as a polynya in the parlance of sea ice researcherswas likely caused by a powerful cyclone that spun up in Antarcticas Weddell sea before migrating eastward into the Lazarev sea in mid-September 2017, according to research published Wednesday in the Journal of Geophysical Research: Atmospheres. 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. They claimed that to be the protectors of planet Earth to protect its inhabitants from the scurrilous activities of the power brokers and nefarious government agencies with impure agendas. After lowering the sediment corer through the borehole, the scientists then lowered it through about 1,600 feet of seawater below the floating ice shelf. Copyright 2023 CBS Interactive Inc.

They had expected the seafloor to be mud, but were dismayed when they hit a boulder, which meant they couldnt get the intended sediment samples. She lives right Why wetlands are so critical for life on Earth, Rest in compost? 96, 320325 (1970). But the new study questions that assumption. Admiral Richard E. Byrd Encounter With A Lost Civilization in Two SOCCOM instruments were trapped in the vortex above Maud Rise and recorded years of observations there. The second lake drained between 2014 and 2015 and is currently filling up again, while the third lake drained just slightly between 2016 and 2017. So, the legacy of the ozone hole story was that effective environmental action can be taken at the international level to resolve global environmental problems. U.S. News: Latest News, Breaking News, Today's News Stories Updat Their findings transformed the fields of atmospheric science and chemical kinetics, and led to global changes in environmental policy. 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. It seemed that each Antarctic spring which for the Antarctic is September, October ozone levels were dropping. Today, 33 years later, the ozone hole is showing its first signs of recovery. Computers were just coming in. Nature 557, 413417 (2018). So, they ultimately wound up corroborating the British Antarctic Surveys story and getting a bit of egg on their faces too.

Something went wrong, please try again later. A year and a half ago, in the middle of the Antarctic winter, satellite images of the frozen continent revealed something wild: a gaping hole in the middle of Antarticas sea ice that spanned thousands of square miles. So, when the Goddard folks mapped all these flags of potentially bad data, they were all over the Antarctic, exactly where the British Antarctic Survey said it should be. If they live out of town but will be flying out of the Memphis hub, they stay overnight in a crash pad, a cheap place to rent close to the airport. Well, the Goddard folks had set quality control software to look at the data automatically as it came back from the satellite and mark as potentially bad data anything that showed levels below a certain amount, and these levels of the prediction of the Antarctic Surveys were below that amount. (See more of the world below Antarctic ice.). Ex-Navy pilot says he saw UFOs that did things his plane could not do. Res. The lakes grow and shrink beneath the ice. 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. Chem. Large bullet holes were visible in the front door, front windows and paneling of the house. How did this mountain lion reach an uninhabited island? WebThere is a hole presumably allowing a very civilization to dwell inside the world. My name is Erik Conway. Res. It became the ozone hole and it seems to me that it certainly made it easier to reach a greater part of the public by having a simple key word that you could describe it by. 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.

National Research Council. Update: This article has been updated to clarify that the cyclone in question formed in the Weddell sea, but migrated east over the Lazarev sea where it generated a polynya. 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. 10, 94519472 (2010). Amid the glow of 24-hour summer sunlight filtering down through fog, they assembled an automobile-sized contraption of pipes, hoses, and boilers. 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. World Meteorological Organization. How a zoo break-in changed the life of an owl called Flaco, Naked mole rats are fertile until they die, study finds. After drilling out the borehole, the scientists lowered a sediment corer and an attached video camera through the ice shelf. 2019 CBS Interactive Inc. All Rights Reserved. Scientists have peered into one of the least-explored swaths of ocean on Earth, a vast region located off the coast of West Antarctica. Now, thats a hero. Admiral Richard E. Byrd Encounter With A Lost Civilization in Antarctica On February 19, 1947, Admiral Richard E. Byrd left Base Camp Arctic and flew northward. What happened on that flight? For years rumors have persisted that on his historic flight to the North Pole, Admiral Byrd flew beyond the Pole into an opening leading inside the Earth. See Admiral Byrd Diary for more details on what was apparently in his secret diary relating to Admiral Richard Byrds expedition of the North Pole. The Montreal Protocol, as its initially written, was a 50% reduction in production of chlorofluorocarbons it was not a ban. As the scientists analyze that mud, it may yield more diatoms. The hole was, in a word, enormous, and it prompted a raft of speculation as to what could have caused it. 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. Google Scholar. de Zafra, R. L. et al. Climate change is also warming the oceans, potentially making it harder for the polynya to refreeze once its been opened. NY 10036. 16th May 1985. It is stabilized, at least for the time being, by a phalanx of floating ice shelves, that hang off its outer edgesof which the Ross Ice Shelf is by far the largest. At 12:10 a.m. Tuesday, one pilots crash pad became a crime scene. And yeah, with nice coloured graphics it hits you in the face. Future US, Inc.

Welcome to the Hollow Earth Research Society, Admiral Richard Byrd andthe Hollow Earth. US Navy pilot tells of an Ancient Alien City found in Antarctica. A Warner Bros. 94, 1148011520 (1989). ISSN 0028-0836 (print). So, while there are lessons, I think with carbon dioxide we are dealing with a much more difficult problem that goes way beyond the parameters that were involved in the ozone hole. Sign up for the Nature Briefing newsletter what matters in science, free to your inbox daily. Also, it was common knowledge that planes were forbidden to fly directly above the north pole. "We're really talking about a water system that is connected to the whole Earth system. A hole that appeared in 2016 and 2017 drew intense curiosity from scientists and reporters. 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.

Google Scholar. Meanwhile, the lakes beneath Academy Glacier drained between 2009 and 2018. Whereas if youre stuck to a rock and youre waiting for food to come to you, then the one bit that comes past this year could go past you.. But he believes it could also have collapsed as recently as 120,000 years ago, the last time that temperatures were about as warm as they are today. Phys. Total ozone has been measured at the British Antarctic Survey stations, Argentine islands and Halley Bay since 1957. In January of 1956, Admiral Byrd led yet another expedition to the South Pole. After the shooting, 23-year-old Dillon Munn rushed to check on his mother. The Southern Ocean is thought to play a key role in global ocean currents and carbon cycles, but its behavior is poorly understood. Changes to the polynya could, in other words, ripple outward across Earths oceans. What is wind chill, and how does it affect your body? ", Related: Photos of Antarctica: The ice-covered bottom of the world. The 2021 Antarctic ozone hole reached its maximum area on Oct. 7 and ranks 13th largest since 1979. It is growing at an "explosive" rate that surprised researchers conducting astudy the agency led on the glacier. A huge collection of photographs that show Australian and British expeditions to Antarctica in the early 20th century have been digitized and released to the public for the first time. The harvesting of fish and plant life are also affected. 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. Conspiracy theorists have actually interpreted these written remembrances as clear evidence that Richard Byrd did actually uncover an entry to the center of the planet. She was previously a senior writer for Live Science but is now a freelancer based in Denver, Colorado, and regularly contributes to Scientific American and The Monitor, the monthlymagazine of the American Psychological Association. In other words, they knew them to be good and rigorous scientists, so the initial questioning of those scientists was, well, how could they get such results because what they had found was ozone concentrations are far lower than anyone had ever seen on Earth. You have to remember that the ozone hole story was sort of simple and straightforward, and that CFCs had not been part of our economy for that long and they were not the same as carbon dioxide which is coming from our basic energy generation, so that the regulations that limited the CFCs could be handled by the economy quite easily.
