Your effort and contribution in providing this feedback is much 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. Or by navigating to the user icon in the top right. Climate change is also warming the oceans, potentially making it harder for the polynya to refreeze once its been opened. The winter ice on the Heuz hopes theres another polynya this winter, so that this instrument can capture any changes taking place in the ocean as its opening. 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. As the scientists analyze that mud, it may yield more diatoms. This is the Nature PastCast, each month raiding Natures archive and looking at key moments in science. It means that 41% of its The research explores why this hole appears in only some years, and what role it could play in the larger ocean circulation. But the new study questions that assumption. Now, thats a hero. Those studies provided only brief glimpses of how deep, warm water circulates under the ice shelf, covering a few hours or days. 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.. National Research Council. 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. "The reason stated because of a air sampling camp in that area. 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.

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. 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. Thankfully, they'll all miss. Montzka, S. A. et al. We cant see it happening. Soc. Over time, these lakes experienced major change.

You are forbidden to enter into a cave with an opening without a federal cave license or a government cavern expert with you. 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. The contention continues thatAdmiral Byrddid make a trip inside the North Pole entrance to the Hollow Earth in 1926. The lakes sit at the bottom of the ice sheet, where the ice meets the rocky Antarctic continent. What was precisely discovered has always been shrouded in mystery, but it may have been astonishing. 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.. The biggest known polynyas at that location were in 1974, 1975 and 1976, just after the first satellites were launched, when an area the size of New Zealand remained ice-free through three consecutive Antarctic winters despite air temperatures far below freezing. 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. 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.

But the events in 2016 and 2017 forced us to reevaluate that, said lead author Ethan Campbell, a UW doctoral student in oceanography. Amid the glow of 24-hour summer sunlight filtering down through fog, they assembled an automobile-sized contraption of pipes, hoses, and boilers. Molina, M. J. 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. 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. 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. It is growing at an "explosive" rate that surprised researchers conducting astudy the agency led on the glacier.

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. Not according to biology or history. It is locked beneath a crust of ice larger than Spain and more than 1,000 feet thick, making its waters perpetually darkand extremely difficult for humans to access. Tom Metcalfe writes about science and space for NBC News. Bats and agaves make tequila possibleand theyre both at risk. As the lakes drain and fill, the ice above rises and falls, offering hints as to what's happening below.
