Brunt Ice Shelf in Antarctica calves new iceberg
A large iceberg (380 km2), about the size of the Isle of Wight, has broken off the 150m-thick Brunt Ice Shelf. It broke off after a crack suddenly appeared in the ice shelf a few weeks ago. The final break happened in the early hours of Monday, 20 Ma.....»»
The skyscraper-sized tsunami that vibrated through the entire planet and no one saw
Earthquake scientists detected an unusual signal on monitoring stations used to detect seismic activity during September 2023. We saw it on sensors everywhere, from the Arctic to Antarctica......»»
Antarctic research finds exceptional warm air intrusions and omnipresent aerosol layers in the stratosphere
Extremely clean air on the ground, warm air intrusions and sulfate aerosol at high altitudes—a Leipzig research project has gained new insights into clouds in Antarctica. From January to December 2023, the vertical distribution of aerosol particles.....»»
Rapid loss of Antarctic ice after 2100 likely under current emissions, climate scientists find
A Dartmouth-led study by more than 50 climate scientists worldwide provides the first clear projection of how carbon emissions may drive the loss of Antarctica's ice sheet over the next 300 years......»»
Whales are recovering from near extinction, but industrial fishing around Antarctica competes for their sole food source
The Southern Ocean encircling Antarctica is the world's largest feeding ground for baleen whales—species like humpbacks that filter tiny organisms from seawater for food. In the 20th century, whalers killed roughly 2 million large whales in the Sou.....»»
Large theropod dinosaurs thrived near South Pole, Australian tracks show
A discovery of dinosaur tracks on Australia's southern coast—dating back to the Early Cretaceous when Australia was still connected to Antarctica—indicates that large theropod dinosaurs thrived in this polar environment, prowling the river floodp.....»»
The ozone hole above Antarctica will keep opening up each spring for decades to come: Why that still matters
At this time of year, as the sun rises over Antarctica, a "hole" opens up in Earth's ozone layer......»»
AI modeling can deliver more benefits, less risk for water partnerships
A Cornell-led research collaboration found that cooperative partnerships seeking to spread the cost burden of water infrastructure projects among regional stakeholders often end up forcing local partners to bear the brunt of underlying supply and fin.....»»
New Lexus brand "taste" will come from sweeping rework of body rigidity
Lexus says it has found the missing piece in its quest to match the long-lauded driving dynamics of Germany's big premium players — better body rigidity. To deliver a better signature, Toyota's top-shelf marque is reworking ride and handling across.....»»
Antarctica vulnerable to invasive species hitching rides on plastic and organic debris, oceanographic model shows
Antarctica's unique ecosystems could be threatened by the arrival of non-native marine species and marine pollution from Southern Hemisphere landmasses, new oceanographic modeling shows......»»
Climate change is already reshaping PNW shorelines: Tribal nations are showing how to adapt
Keeley Chiasson plodded through the steep, sandy sediment near the base of the bluff. Carefully perched on a firm shelf, she scraped back the weathered surface of the wall, revealing stripes of cocoa, rust and tan sediments......»»
As human activities expand in Antarctica, scientists identify crucial conservation sites
A team of scientists led by the University of Colorado Boulder has identified 30 new areas critical for conserving biodiversity in the Southern Ocean surrounding Antarctica. In a study published Aug. 15 in the journal Conservation Biology, the resear.....»»
Antarctica winter experiences prolonged heat wave
Antarctica, the world's coldest continent, is experiencing an exceptionally long heat wave during its winter, according to Britain's national polar research institute......»»
First map of vegetation across Antarctica reveals a battle for the continent"s changing landscape
A tiny seed is stuck between loose gravel and coarse sand. There is nothing else alive around it. All it can see is a wall of ice reaching 20 meters up into the sky. It is cold. Survival is hard around here. In winter, it is dark even during the day......»»
Weather "whiplash" in Antarctica may help predict effects of future climate change
The McMurdo Dry Valleys of Antarctica live up to their name. The region is one of the driest places on Earth—mountains form a wall around the valleys and prevent melting glacier water from intruding, humidity is extremely low, and no rain was docum.....»»
Tackling digital sexual violence in Canada requires updated policies and procedures
Online abuse affects one in six school-aged children, according to a recent World Health Organization survey of Europe, Asia and Canada. This statistic is just the tip of the iceberg when it comes to online abuse, though, as this issue affects more t.....»»
Study yields new insights into the link between global warming and rising sea levels
A McGill-led study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the curre.....»»
Ancient Antarctic microorganisms are aggressive predators
In Antarctica there is a small lake, called Deep Lake, that is so salty it remains ice-free all year round despite temperatures as low as -20°C in winter. Archaea, a unique type of single-celled microorganism, thrive in this bitterly cold environmen.....»»
Underwater mapping reveals new insights into melting of Antarctica"s ice shelves
An international research team—including scientists from the University of East Anglia (UEA)—deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica. The underwater vehicle, "Ran," was programmed to dive into the cavity.....»»
Insights into strawberry senescence: Hormonal interplay key to extending shelf life of "Benihoppe" variety
A research team discovered that the rapid senescence of harvested strawberry "Benihoppe" results from increased perishability, softening, water loss, increased soluble sugars within 2 d, and changes in hormone levels. They found that ABA, JA, and eth.....»»
Mega-iceberg melt affects important marine ecosystem
Scientists have for the first time taken in-situ ocean measurements during the collapse of a giant iceberg in the sub-Antarctic. These new observations reveal how ocean ecosystems may be affected if more icebergs calve due to warmer ocean temperature.....»»
