One way that a surface polynya matters for the climate is for the deepest water in the oceans, known as Antarctic Bottom Water. Scientists fear that some of these ice shelves are already weakening. 10, 94519472 (2010). Broken glass was everywhere. The study shows that when winds surrounding Antarctica draw closer to shore, they promote stronger upward mixing in the eastern Weddell Sea. 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. Web6.1M views 2 years ago The Moon rotates around the Earth at about the same speed, as it does around its axis, thats why we can only see one side of it. "This did not make any sense to any of us on the crew because on two different occasions we had to fly over this area. Stephanie Pappas is a contributing writer for Live Science, covering topics ranging from geoscience to archaeology to the human brain and behavior. Solomon, S., Garcia, R. R., Rowland, F. S. & Wuebbles, D. J. Interestingly, the said moment of the historic exploration was caught on camera thanks to a researcher who lowered his camera down an 83 meter hole in the continent. Environment | News releases | Research | Science, The hole in the sea ice offshore of the Antarctic coast as seen by a NASA satellite on Sept. 25, 2017.NASA Worldview/NASA Blue Marble. The winter ice on the surface of Antarcticas Weddell Sea occasionally forms an enormous hole. and JavaScript. You could fly one of our LC130 into this thing. The geologists were more than 150 miles from the open ocean when they bored a hole through the 3,000-foot-thick ice with a hot-water drill and lowered a coring Tolbert, M. A., Rossi, M. J., Malhotra, R. & Golden, D. M. Science 238, 12581260 (1987). "As more heat and water get under the glacier, it melts faster.". Im pretty sure they aint out here riskin it.. In a stroke of scientific luck, a big one appeared for the first time in decades. Discovery Company. The ozone hole was mentioned in newspapers and on TV quite commonly during the 1980s because the interest of environmental organisations kept it on the public radar, I think. 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. 4, 741749 (2011). The 2021 Antarctic ozone hole reached its maximum area on Oct. 7 and ranks 13th largest since 1979.

Ex-Navy pilot says he saw UFOs that did things his plane could not do. The contention continues thatAdmiral Byrddid make a trip inside the North Pole entrance to the Hollow Earth in 1926. What we discovered at our Antarctic station was quite curious. Right now people think most of the bottom water is forming on the Antarctic shelf, but these big offshore polynyas might have been more common in the past, Riser said. A recent study, published in The Journal of Nuclear Medicine, has found that individuals who use electronic cigarettes, or e-cigarettes, experience greater lung inflammation compared to cigarette smokers and non-smokers. & Rowland, F. S. Nature 249, 810812 (1974). Munn said his thoughts are on his mother and moving her to a safer neighborhood. It comes after sensational claims surfaced that NASA was hiding a "sinister secret" about the moon. Scientists say the glacier is responsible for about four percent of global sea level rise. Something went wrong, please try again later. This is the first study to demonstrate that using e-cigarettes to vape e-liquids results in a unique inflammatory Stephanie received a bachelor's degree in psychology from the University of South Carolina and a graduate certificate in science communication from the University of California, Santa Cruz. Fricker's breakthrough opened up the possibility of tracking the lake system over time. (See more of the world below Antarctic ice.). New York, The pocket is a sign of "rapid decay" and just one of "several disturbing discoveries" made recently regarding the glacier, NASA's Jet Propulsion Laboratory said in a news release Wednesday. This means that we may include adverts from us and third parties based on our knowledge of you. This time around, the New Zealand team installed instruments in one of their holes that will monitor ocean currents and water temperatures under the ice for the next two years or so, beaming that information home via satellite link. These are the first observations to prove that even a smaller polynya like the one in 2016 moves water from the surface all the way to the deep ocean. We cant see it happening. 2019 CBS Interactive Inc. All Rights Reserved. ICESat, however, collected data for only six years. NASA Worldview/NASA Blue Marble. 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. After the visit, Byrd and his crew were guided back to the outer area of the Earth. Heuz hopes theres another polynya this winter, so that this instrument can capture any changes taking place in the ocean as its opening. The New Zealanders project could shed light on this question. Newman, P. A. Atmos. 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. In any given year you could have several of these things happen, but unless you get them all, then you dont get a polynya.. Majestic Twelve (MJ 12) was originally conceived by a man named Jesse Marcel, who had been involved with the first Roswell UFO event.Majestic Twelve (MJ 12) was the alleged code label of a secret committee of experts, military top leaders, and government authorities, supposedly developed in 1947 by an executive order of the then US president, Harry S. Truman. 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. Your effort and contribution in providing this feedback is much 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. Its been quite fascinating going back, particularly along the Antarctic Peninsula, on various trips. These lakes fill and drain over and over again in largely mysterious cycles that may influence how fast the ice sheet moves and how and where meltwater reaches the Southern Ocean. 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. It is growing at an "explosive" rate that surprised researchers conducting astudy the agency led on the glacier. We need to improve our models so we can study this process, which could have larger-scale climate implications.. A Warner Bros. Molina, M. J. He went on to become the single greatest polar explorer of the century, a feat recognized by the American government when they awarded him the Medal Honor, the highest recognition of achievement for heroism in that country and the greatest military honor. Many are military veterans. Atmos. I started at the present and was going to work back, and my colleagues really didnt believe that this was significant. Get browser notifications for breaking news, live events, and exclusive reporting. Atmos. The Ross Ice Shelf has come and gone probably many times in the last million years, says Scherer. What was precisely discovered has always been shrouded in mystery, but it may have been astonishing. According to some, Bryd had actually found an additional world in the Hollow Earth, though his journal was mysteriously removed by the government. Their findings transformed the fields of atmospheric science and chemical kinetics, and led to global changes in environmental policy. Visit our corporate site (opens in new tab). CBS News climate and weather contributor Jeff Berardelli reports that the cavity is likely a significant finding because the West Antarctic ice sheet is considered one of the most unstable and vulnerable. There are still animals out there that can break the rules that we have written for them.. Im really trying to figure out what happened, said Munn.

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. Atmos. Multiple rounds went into the front bedroom. 1). 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.
