“If you don’t have water, you’re not going to get very far.” Making sense of that subglacial hydrology is especially important for researchers racing to model particularly precarious regions of ice, like the Thwaites Glacier, a few hundred miles away from Whillans.
Last month, Milillo and other scientists reported that tidal pumping is forcing the rapid retreat of the grounding lines of other West Antarctica glaciers—Pope, Smith, and Kohler.
“We don’t know anything about king penguins at Martillo Island,” says Sami Dodino, a penguinologist at Argentinian scientific institute CADIC.Ushuaia, right at the southern tip of Argentina, is known fondly as “The End of the World.” Travel around 1,000 km south and the next place you reach is Antarctica (although not before passing through another settlement on the Chilean side of the Beagle Channel, Puerto Williams—“Beyond the End of the World”).
The ship leaves Wellington and heads south with 20 science staff and 19 crew on board to learn more about key environmental and biological processes in the Ross Sea. Voyage leader and fisheries scientist Dr Richard O’Driscoll says this is the third in a series of voyages focused on providing baseline information about the Ross Sea Marine Protected Area (MPA) established in 2017.
Satellite images have revealed 11 previously unknown emperor penguin colonies in Antarctica, boosting the number of known colonies of the imperilled birds by 20 percent.Philip Trathan, also at BAS, said: “The new breeding sites are all in locations where recent model projections suggest emperor penguins will decline.
New measurements from the ocean under the centre of the Ross Ice Shelf have significantly improved our understanding of the complex processes that drive melting in Antarctica.
These neutrinos that Anita was searching for would be classified among the most energetic particles in the universe, which physicists believe are produced by the same processes that generate jets of charged particles called ultrahigh-energy cosmic rays.
NIWA researchers have helped unlock information trapped in ancient air samples from Greenland and Antarctica that shows the amount of methane humans are emitting into the atmosphere from fossil fuels has been vastly underestimated.
But step into the Martian-like dry valleys and you’ll be treading on a bustling community of tiny organisms, like nematode worms and ultra-hardy water bears and mites.“Really, that's the charismatic megafauna of continental Antarctica,” says evolutionary ecologist Byron Adams of Brigham Young University, who is currently surveying life on the continent.
It’s certainly possible for ordinary folk to help with collecting microplastic samples, as Airbnb intends participants to: Bergmann and her team had regular people living on a Norwegian archipelago pack up snow samples for a study themselves.
The fiery orange submarine, which she named Ran after the Norse goddess of the sea, hadn’t yet resurfaced from its first mission in the watery depths around the face of West Antarctica’s Thwaites Glacier.“She’s a very temperamental lady,” Wåhlin said of the $3.6 million, unmanned submarine, while peering through her binoculars on an overcast March day.
But some researchers have found a new way to use satellites to figure out what penguins eat by capturing images of the animal’s poop deposits across Antarctica.A group of scientists studying Adélie penguins and climate change have found that the color of penguin droppings indicates whether the animals ate shrimp-like krill (reddish orange) or silverfish (blue).
But he wanted to know what was going on deep below Thwaites, where its ice met the earth.If the mysterious Thwaites Glacier were to “go bad,” it might change the course of civilization.During that 2008 expedition and another a year later, Anandakrishnan’s team performed the geologic equivalent of an ultrasound on Thwaites.
“To do that, we need to find rocks that are the right type, the right age and that are exposed.”The fossils he hopes to find are preserved in sedimentary deposits that exist in several places around the globe, but what makes Antarctica special for fossil hunters is the fact that there is no rain or snow to erode them away.After the fish died those millions of years ago, they were covered by layers of silt and mud in the river delta.
NIWA marine ecologist Dr Kimberly Goetz is leading two trips to Antarctica to study the seals as a way to examine the effectiveness of the newly-created Ross Sea Marine Protected Area (MPA) in conserving top predators.
Rather, these penguins, who were mummified by the cold, dry Antarctica environment, likely died from weather on the opposite end of the spectrum: two extremely rainy and snowy events that happened over the past 1,000 years, a new study finds.
