That depends on if you're talking about the intangible trait or the ship that Shackleton and his crew took from South Georgia Island to Antarctica. The latter--the ... In the Antarctic summer of January and February, international explorers will assemble to study an ice shelf and the treacherous Weddell Sea.
In that situation, abnormally warm water could cause the glaciers that hold back ice sheets on top of Antarctica and Greenland to collapse. That would ... The pooling of warm water beneath Antarctic glaciers makes rapid glacier melt more likely, which increases the possibility of ice shelf collapse and rapid sea-level rise. climate change

"We found that in this way increased glacial meltwater can cause a positive feedback, driving further melt of ice shelves and hence an increase in sea level rise." The study found that fresh meltwater also reduces the formation and sinking of dense water in some regions around Antarctica, slowing ... sea
The scientists on board the Agulhas II hope that by studying the cavity under the Larsen C ice shelf with autonomous underwater vehicles (AUVs), they can determine if the recent breakup of ice shelves along the Antarctic Peninsula is a new development in geological terms, or if it is something that ... Ship
SA to play role in Antarctic expedition to study ice shelf and marine life ... It will study the ice shelf and marine life of the Larsen C ice shelf. ... "Antarctica has about 1.5-million square kilometres of floating ice shelves‚ which have been surveyed and studied from above‚ but only very rarely from beneath.
An international expedition next year will try to reach the site of a major new iceberg. The Weddell Sea Expedition 2019 aims to study the Larsen C Ice Shelf and, if it gets the opportunity, to seek out the seafloor location of Ernest Shackleton's lost ship, Endurance. Expedition leader, Prof Julian ... Antarctica

An ambitious new mapping project has given scientists one of their most complete looks yet at the movement of glaciers all around Antarctica. ... At the grounding line, the ice detaches from the bedrock and juts out into the water as a kind of floating ledge, or ice shelf, which helps to stabilize the glacier ...
Last month, we reported on a plan put forth by scientists at Princeton University to slow down melting of the Antarctic ice shelf. One of those plans calls for ... of the paper, tells The Guardian. "The changes mean that very soon the sea-level contribution from Antarctica could outstrip that from Greenland.".
The grounding line retreat reinforces concerns about a worst-case Antarctic meltdown scenario, with global sea level rising 10 feet by 2100. Along with the melting from below caused by warm ocean water, a 2015 study showed how global warming is melting ice shelves from above by causing more ... Antarctica

The Ross Ice Shelf, a country-sized colossus of chilly residue hanging off continental Antarctica, is the world's largest floating chunk of ice – and a marvellous ... It's not unreasonable to think that this might mean ice shelves are going to melt faster from beneath and become more unstable as time goes on. drones
The ecosystems of the seafloor beneath Antarctica's floating ice shelves are unique and rarely studied: According to BAS scientists, the seafloor exposed by the A-68 iceberg has been completely covered by the ice shelf for up to 120,000 years, in total darkness and connected to the open ocean by only ... drones
In November, scientists from New Zealand used a hot water drill to go deep into Antarctica's Ross Ice Shelf.

He said climate change had already affected the seas around Antarctica and is warming some coastal waters. “Future warming may make some habitats warm. Where these habitats support unique species that are adapted to love the cold and not the warm, those species are going to either move or die. drones

Stevens and his colleagues hoped to assess the health of the Ross Ice Shelf by measuring water temperatures and ... drones
Antarctica's Ross Ice Shelf is a Spain-sized sheet of ice fed by the continent's glaciers. But unlike other Antarctic ice shelves such as Larsen C, which recently calved a 1-trillion-metric-ton iceberg, the Ross Ice Shelf's mass has remained roughly constant over the last several decades, even in the face of ... drones
Scientists from the British Antarctic Survey are taking off this Wednesday to explore a once-inaccessible marine ecosystem beneath the Larsen C ice shelf—where an iceberg the size of Delaware broke off last summer.

They also confirmed that the flow of West Antarctica's Thwaites and Pine Island glaciers into the ocean continues to accelerate, albeit at a slower rate. The study confirmed that ice flow from West Antarctica--the Amundsen Sea sector, the Getz Ice Shelf and Marguerite Bay on the western Antarctic ... drones
