Latest Pine Island Glacier Stories

2011-11-08 04:18:48

NASA will host a media teleconference at 11 a.m. EST on Wednesday, Nov. 9, to discuss a new field campaign season on one of Antarctica's "hottest" spots: the rapidly-melting Pine Island Glacier. The Pine Island Glacier ice shelf expedition, an international effort led by seven institutions, aims to peek beneath the ice and determine how the ocean is melting the glacier's underbelly. During the news conference, panelists will discuss this season's scientific goals, state-of-the-art data...

Operation IceBridge: Watching The Birth Of An Iceberg

[ Watch the Video ] After discovering an emerging crack that cuts across the floating ice shelf of Pine Island Glacier in Antarctica, NASA's Operation IceBridge has flown a follow-up mission and made the first-ever detailed airborne measurements of a major iceberg calving in progress. NASA's Operation Ice Bridge, the largest airborne survey of Earth's polar ice ever flown, is in the midst of its third field campaign from Punta Arenas, Chile. The six-year mission will yield an...

Image 1 - Glacier Could Raise Global Sea Levels In 20 Years Less Than Thought
2011-10-27 11:53:03

Researchers said on Wednesday that an Antarctic glacier with the potential to raise global sea levels could speed up its retreat within 20 years. Columbia University researchers said the Thwaites Glacier is expected to speed up once it detaches from an underwater ridge it is currently attached too. The ridge appears to be slowing the glacier's slide into the sea, but the finding says the glacier is losing its grip on a previously unknown ridge. The researcher said this explains why...

Scientists To Study Underground Lake In Antarctica

An Antarctic lake hidden under 1.8 miles of ice in the western region of the continent could reveal what life on Earth looked like a million years ago and could narrow down the search for extraterrestrial life, as well as give scientists clues to future climate impacts, according to a British expedition taking up the study. Expedition members will use hot water to melt down through the nearly 2-mile-thick ice to reach Lake Ellsworth, which has been isolated from the outside world for more...

A major glacier is undermined from below Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A growing cavity beneath the ice shelf has allowed more warm water to melt the ice, the researchers say"”a process that feeds back into the ongoing rise in global sea levels. The glacier is currently sliding into the sea at a clip of four...

Scientists have previously shown that West Antarctica is losing ice, but how that ice is lost remained unclear. Now, using data from Earth observing satellites and airborne science missions, scientists are closing in on ice loss culprits above and below the ice. The findings, presented Dec. 15 at the fall meeting of the American Geophysical Union (AGU) in San Francisco, Calif., are expected to improve predictions of sea level rise.

Scientists returned this week to the Southern Hemisphere where NASA's Operation IceBridge mission is set to begin its second year of airborne surveys over Antarctica. The mission monitors the region's changing sea ice, ice sheets and glaciers. Researchers will make flights from Punta Arenas, Chile, on NASA's DC-8, a 157-foot airborne laboratory equipped with a suite of seven instruments. The focus is on re-surveying areas that are undergoing rapid change and embarking on new lines of...

A robotic yellow submarine that has been launched deep beneath the Pine Island Glacier has helped to solve a mystery about one of Antarctica's fastest-melting glaciers, adding to unease about how climate change may lead to higher world sea levels, scientists reported on Sunday in the journal Nature Geoscience. Scientists captured ocean and sea-floor measurements using the robotic submarine, called Autosub. The team found that the glacier was no longer resting on a sub-sea ridge that had...
