Satellite images from Aug. 30, 2017 through Dec. 2, 2017 show the rarely-seen opening in the late Southern Hemisphere winter sea ice. 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. It is said that there is a US regulation to prevent citizens from checking out caverns and holes in the polar regions. We were looking for, at most, a few percent change in ozone and we werent necessarily looking in Antarctica. A great many people compare the ozone depletion problem and the climate change problem. The paper really changed the way people look at the environment. Other co-authors on the paper are Kent Moore at the University of Toronto, who was the 2016-17 Canada Fulbright Visiting Chair in Arctic Studies at the UW; Casey Brayton at the University of South Carolina; and Lynne Talley and Matthew Mazloff from Scripps Institution of Oceanography at the University of California, San Diego. This water system was largely invisible until the advent of NASA's ICESat mission in 2003. She's revealed the secrets to maintaining a youthful glow and looking glamorous, World Cup's sexiest fan wows in barely-there bikini as followers call her 'breathtaking', Former Miss Croatia Ivana Knoll continues to wow her millions of followers as she asks "watermelon or peach?" The hole in the sea ice offshore of the Antarctic coast as seen by a NASA satellite on Sept. 25, 2017. The growing cavity sits in West Antarctica at the bottom of Thwaites Glacier, which is about as big as Florida and contains enough ice to contribute more than 2 feet to sea level rise, NASA said. Youve been listening to the Nature PastCast, produced by Charlotte Stoddart and with contributions from Jonathan Shanklin, Richard Stolarski and historian Erik Conway. Broken glass was everywhere. WebThere is a hole presumably allowing a very civilization to dwell inside the world. ", Related: Photos of Antarctica: The ice-covered bottom of the world. Why? (See more of the world below Antarctic ice.). 94, 1148011520 (1989). Copyright 2023 CBS Interactive Inc. All rights reserved. Nature. Now, a team of researchers has bored a hole through the ice and sampled the ocean beneath it. Your effort and contribution in providing this feedback is much 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. Phys. 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. As Heuz put it, everythings connected.. US Navy pilot tells of an Ancient Alien City found in Antarctica. Cold, dark and alive! When is it going to stop?. Atmos. In that region, an underwater mountain known as Maud Rise forces dense seawater around it and leaves a spinning vortex above. Some complained we shouldnt use that term, but once you let that term out of the bag, there was no going back. 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. 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. The study also used data from the long-running Argo ocean observing program, elephant seals that beam data back to shore, weather stations and decades of satellite images. 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. I started at the present and was going to work back, and my colleagues really didnt believe that this was significant. 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. The contention continues thatAdmiral Byrddid make a trip inside the North Pole entrance to the Hollow Earth in 1926. Youve got so much crime going on. Never was a problem. But the new study questions that assumption. Some of the Special Reports available at the. These animals can sniff it out. Benedick, R. A. Ozone Diplomacy: New Directions in Safeguarding the Planet (Harvard Univ. I was given the task of writing the programmes, supervising the digitisation of the data and processing it. In January of 1956, Admiral Byrd led yet another expedition to the South Pole. Ozone is an invisible upper atmospheric gas that protects all forms of life on Earth from most of the Suns damaging radiation, radiation that can cause skin cancer, eye damage and suppression of the immune system. NASA warns of 3 skyscraper-sized asteroids headed toward Earth this week. When I first went to Rothera, we used to get drinking water in the summer from a melt pool that formed on a patch of ice nearby. Analysis shows that when the surface ocean is especially salty, as seen throughout 2016, strong winter storms can set off an overturning circulation. In order to survive, the organisms would have to feed on floating material from other animals or plants, because it is impossible for plants to photosynthesize in the sunless seawater. It seemed that each Antarctic spring which for the Antarctic is September, October ozone levels were dropping. But theres a lot of work ahead before. The last time I was at Rothera, we couldnt do that because the ice level had dropped so much that the water just spilled out into the sea and Ive seen the glaciers retreating, slowly, admittedly, but I can see that theyre going back and yes, change is very obvious along the Antarctic Peninsula. The New Zealanders project could shed light on this question. 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 Now, a team of researchers has bored a hole through the ice and sampled the ocean beneath it. Campbell joined the UW as a graduate student in 2016 to better understand this mysterious phenomenon. 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. Stephanie Pappas is a contributing writer for Live Science, covering topics ranging from geoscience to archaeology to the human brain and behavior. Now, a team of researchers think they know what caused it. He was killed for his knowledge. in Stratospheric Ozone Depletion and Climate Change (ed. 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. The Goddard team was scooped and they knew it. Im pretty sure they aint out here riskin it.. Over time, these lakes experienced major change. She lives right across the street from where the FedEx pilot was hit by gunfire. For an optimal experience visit our site on another browser. NASA/AP. We thought this large hole in the sea ice known as a polynya was something that was rare, maybe a process that had gone extinct. Google Scholar. In this show, were exploring a paper published in the 1980s. Amid the glow of 24-hour summer sunlight filtering down through fog, they assembled an automobile-sized contraption of pipes, hoses, and boilers. 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. Some of those dead diatoms were only a few hundred thousand years old, leading Scherer to an astounding conclusion: this area, now covered by 3,000 feet of ice, had recently been open sea, bathed in life-sustaining sunlight that could support the diatoms growth. 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. The researchers think the cyclones winds pushed the ice outward from its center, creating a hole that would continue to expand over the days to come. Its just a theory. After drilling out the borehole, the scientists lowered a sediment corer and an attached video camera through the ice shelf. Their findings transformed the fields of atmospheric science and chemical kinetics, and led to global changes in environmental policy. Climate change is also warming the oceans, potentially making it harder for the polynya to refreeze once its been opened. 96, 320325 (1970). Pyle, J.

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. These hidden gems of frigid water are part of a vast network of ever-changing lakes hidden beneath 1.2 to 2.5 miles (2 to 4 kilometers) of ice on the southernmost continent. In 1925 there was a singular man on a mission to explore desolate lands rarely seen by humans to that time Admiral Richard Byrd. Global sea levels would rise by 10 feet if West Antarctica lost these crucial stabilizers and spilled its ice into the ocean. The study shows that when winds surrounding Antarctica draw closer to shore, they promote stronger upward mixing in the eastern Weddell Sea. Lett. Heuz hopes theres another polynya this winter, so that this instrument can capture any changes taking place in the ocean as its opening.

This machine generated a powerful jet of hot water, which they used to melt two narrow holes, each a few inches across, more than 1,100 feet down to the bottom of the ice. 101, 38853890 (1996). Its European Space Agency equivalent, CryoSat-2, collected similar data starting in 2010 but over a broader area and with less precision. 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. The finding waspublished Mondayin Frontiers in Marine Science. So said the great explorer, Admiral Richard Byrd. You can also search for this author in PubMed Scherer, a micro-paleontologist now at Northern Illinois University in DeKalb, found this subglacial mud chockablock full of microscopic diatom shellsbeautiful glassy objects, reminiscent of fine vases. 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. At 12:10 a.m. Tuesday, one pilots crash pad became a crime scene. What they found in that paper was, during the springtime, a 40% or more decline and that that 40% only ten years earlier was not there, so this happened very rapidly. New AI may pass the famed Turing test.
