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.....»»
Melting ice, falling snow: Sea ice declines enhance snowfall over West Antarctica
As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise, according to Penn State scientists......»»
Study finds that colostrum is key to saving beef calves from trouble
In a pair of recent studies, researchers examined risk factors that contribute to insufficient antibody transfer to newborn beef calves, as well as the subsequent negative health effects. They found that the mother's parity (in "heifers" or first-tim.....»»
Investigators are being sent to US research base on Antarctica to look into sexual violence concerns
The watchdog office overseeing the National Science Foundation is sending investigators to Antarctica's McMurdo Station after hearing concerns about the prevalence of sexual violence at the U.S. research base......»»

Underwater robot finds new circulation pattern in Antarctic ice shelf
More than merely cracks in the ice, crevasses play an important role in circulating seawater beneath Antarctic ice shelves, potentially influencing their stability, finds Cornell University-led research based on a first-of-its-kind exploration by an.....»»
Waves of change: How sea-levels and climate altered the marine ecosystems at the South Pole 390–385 million years ago
During the Early-Middle Devonian period, a large landmass called Gondwana—which included parts of today's Africa, South America, and Antarctica—was located near the South Pole. Unlike today's icy conditions, the climate was warmer, and the sea le.....»»
Climate research: How the Greenland ice sheet can still be saved
Greenland is the second largest permanently ice-covered surface on the Earth; only Antarctica is larger. The Greenland ice sheet is drastically impacted by the effects of climate change. If the ice sheet melts completely it would cause a sea level ri.....»»
Ice sheet surface melt is accelerating in Greenland and slowing in Antarctica, finds study
Surface ice in Greenland has been melting at an increasing rate in recent decades, while the trend in Antarctica has moved in the opposite direction, according to researchers at the University of California, Irvine and Utrecht University in the Nethe.....»»
Here"s why farmers are bearing the brunt of big food companies" decarbonization efforts
More than a third of the global greenhouse gas emissions resulting from human activity can be attributed to the way we produce, process and package food. So it comes as no surprise that many large companies involved in food production and retailing a.....»»
Bizarre year for sea ice notches another record
Antarctica finishes well below any other year in the satellite era. Enlarge / 2023 has been a remarkable year for Antarctic sea ice. (credit: National Snow and Ice Data Center) Sometimes, data points deemed to be “outl.....»»
More than 20-year-old assumption about beer aroma disproved
Hops-derived constituents not only increase shelf-life and bitterness of beer, but can also significantly influence aroma. An important hop odorant is linalool, which has a floral and citrus-like scent......»»
At US Antarctic base hit by harassment claims, workers are banned from buying alcohol at bars
From Sunday, workers at the main United States base in Antarctica will no longer be able to walk into a bar and order a beer, after the federal agency that oversees the research program decided to stop serving alcohol......»»
As Antarctic sea ice continues its dramatic decline, we need more measurements and much better models
After two seasons of record-breaking lows, Antarctica's sea ice remains in dramatic decline, tracking well below any winter maximum levels observed since satellite monitoring began during the late 1970s......»»
Antarctic sea ice hits lowest winter maximum on record: US data
The sea ice around Antarctica likely had a record low surface area when it was at its maximum size this winter, a preliminary US analysis of satellite data showed Monday......»»
Study finds Antarctica"s glacial border migrates for miles with the tide
The grounding line of the southern Ronne Ice Shelf in Antarctica can shift up to 15 km with changing tides, new analysis shows. The research, published today in The Cryosphere, examines the key region where land-based Antarctic ice spills over into t.....»»
Study explores supergiant iceberg"s huge impact on surrounding ocean surface
The melting of the supergiant iceberg A-68 had a huge impact on the ocean around South Georgia, in sub-Antarctica, and significantly changed the Southern Ocean's temperature and saltiness, with potentially major consequences for this ecologically sig.....»»
Using "spent" coffee and tea to boost shelf life and nutritional value of cakes
On a crisp fall afternoon, there are few pairings better than a hot beverage and a sweet pastry. But what if you could use the left-over tea leaves or coffee grounds from the drink to make that tasty treat a healthier one, too? Researchers reporting.....»»
Tight on space? You still have room for a printer — if it’s the Brother MFC-J1205W
Brother's MFC-J1205W INKvestment Tank is a surprisingly compact all-in-one printer that fits on a shelf, but it isn't like other tank printers......»»
Polar experiments reveal seasonal cycle in Antarctic sea ice algae
In the frigid waters surrounding Antarctica, an unusual seasonal cycle occurs. During winter, from March to October, the sun barely rises. As seawater freezes it rejects salts, creating pockets of extra-salty brine where microbes live in winter. In s.....»»
Heat waves are hitting Antarctica too now
The world saw another year full of extreme weather events resulting from climate change in 2022, from intense storms to soaring temperatures and rising sea levels. Antarctica was no exception, according to new research published this week......»»
