NASA tracking the influence of tides on ice shelves in Antarctica
Ice shelves, the floating extensions of the Antarctic and Greenland ice sheets, are not simply resting on the ocean waters: they rise, fall and bend with the tides. Ultimately, these oceanic motions...
View ArticleWarming ocean water undercuts Antarctic ice shelves
"Upside-down rivers" of warm ocean water threaten the stability of floating ice shelves in Antarctica, according to a new study led by researchers at the University of Colorado Boulder's National Snow...
View ArticleSea-level rise could nearly double over earlier estimates in next 100 years
A new study from climate scientists Robert DeConto at the University of Massachusetts Amherst and David Pollard at Pennsylvania State University suggests that the most recent estimates by the...
View ArticleUGA Skidaway Institute starts study on dynamic Cape Hatteras waters
Sometimes called the "graveyard of the Atlantic" because of the large number of shipwrecks there, the waters off Cape Hatteras on the North Carolina coast are some of the least understood on U.S.'s...
View ArticleNansen gives birth to two icebergs
Multiple satellites, including Europe's Sentinels, have captured images of two large icebergs that broke away from Antarctica's Nansen ice shelf on 7 April.
View ArticleGreen light for plant-based food packaging
Bioplastic packaging that extends the shelf life of food and tells us when it is no longer fit to eat will result in less waste.
View ArticleImage: Antarctic Peninsula ice flow
Successive radar images captured by the Copernicus Sentinel-1A satellite during December 2014 – March 2016 were used to create this spectacular map showing how fast the ice flows on the Antarctic...
View ArticleFingerprint algorithm helps researchers characterize ripples on the ocean...
Human fingerprints are unique identifiers. The wiggles, curves and ripples cannot be copied or duplicated and provide a distinct signature that represents an individual.
View ArticleHow do food manufacturers pick those dates on their product packaging – and...
No one wants to serve spoiled food to their families. Conversely, consumers don't want to throw food away unnecessarily – but we certainly do. The United States Department of Agriculture estimates...
View ArticleRapid, low-temperature process adds weeks to milk's shelf life
A rapid heating and cooling of milk significantly reduces the amount of harmful bacteria present, extending by several weeks the shelf life of one of the most common refrigerator staples in the world,...
View ArticleNew detector at South Pole shows early success at neutrino hunting
In the second it takes to read these words, 65 billion neutrinos will shoot through every square centimeter of your body. Luckily, these infinitesimal particles don't do any harm—they pass through us,...
View ArticleSalad days – tomatoes that last longer and still taste good
The tomato (Solanum lycopersicum) is one of the most valuable fruit crops in the world with an annual global value in excess of $50bn. We eat so many they also play an important role in our diet...
View ArticleSubantarctic seabed creatures and past climate
A new marine biodiversity study in one of the largest Marine Protected Areas in the world reveals the impact of environmental change on subantarctic seabed animals and answers big questions about the...
View ArticleScientists use undersea drones to help predict hurricanes
As Hermine worked its way up the East Coast, scientists deployed several underwater drones they say will help them better understand what sustains and strengthens hurricanes and tropical storms—and...
View ArticleIce shelf vibrations cause unusual waves in Antarctic atmosphere
Low-frequency vibrations of the Ross Ice Shelf are likely causing ripples and undulations in the air above Antarctica, a new study finds. Using mathematical models of the ice shelf, the study's authors...
View ArticleGetting to know the Getz Ice Shelf
As scientists and crew with NASA's Operation IceBridge mission prepared for a research flight on Nov. 5, 2016, the weather in Punta Arenas, Chile, was cold, wet, and windy. But when they reached their...
View ArticleImproving cryopreservation for a longer-lasting blood supply
Freezing and reanimating your body is still science fiction, but cryopreserving cells and certain tissues for future use is a reality. Still, the process could use some improvements to make it more...
View ArticleNASA nears finish line of annual study of changing Antarctic ice
Operation IceBridge, NASA's airborne survey of changes in polar ice, is closing in on the end of its eighth consecutive Antarctic deployment, and will likely tie its 2012 campaign record for the most...
View ArticleWest Antarctic ice shelf breaking up from the inside out
A key glacier in Antarctica is breaking apart from the inside out, suggesting that the ocean is weakening ice on the edges of the continent.
View ArticleAntarctica has a new explorer testing the water along a critical ice shelf
A short metal tube packed with scientific instruments parachuted into the ice-cold waters of Antarctica's Ross Sea on Tuesday, marking a new frontier in polar research. This ALAMO float and five others...
