Extreme melt Antarctica George VI Ice Shelf
2021/3/12
Antarctica's northern George VI Ice Shelf experienced record melting during the 2019-2020 summer season compared with 31 previous summers of dramatically lower melt, a University of Colorado Boul...
Researchers have uncovered a critical connection between winds at Earth's equator and atmospheric waves 6,000 miles away at the South Pole.The U.S. National Science Foundation-funded team has fou...

2020/7/31
The discovery of the first active methane seep in Antarctica is providing scientists with a new understanding of the methane cycle, and the role methane found in this region may play in warming the pl...
Robotic underwater vehicle snaps first images of seafloor beneath Antarctica's Thwaites Glacier（图）
Robotic underwater vehicle snaps first images seafloor beneath Antarctica Thwaites Glacier
2020/2/20
During the first study of the ocean floor beneath Antarctica’s Thwaites Glacier, scientists took images of the glacier's foundations. Thwaites now accounts for about 4% of global sea level rise, and r...
When the temperature drops below freezing, snow and ice often follow. But that's not always the case in Antarctica, where for the first time, drizzle has been recorded at temperatures well below freez...
Reframing the dangers Antarctica's meltwater ponds pose to ice shelves and sea level
dangers Antarctica meltwater ponds pose ice shelves sea level
2019/11/15
Dangers to ancient Antarctic ice portend a future of rapidly rising seas, but a new study, partially funded by NSF, may relieve one nagging fear. Meltwater ponds fracturing the ice below them may not ...

Scientists set expedition investigate Iceberg Alley Antarctica
2019/11/22
The 5.4 million-square-mile Antarctic Ice Sheet is the greatest mass of fresh water on Earth. If it all were to melt, it would raise global sea levels some 220 feet. Searching for answers to how fast ...
CHANGES IN VELOCITY OF FISHER GLACIER, EAST ANTARCTICA USING PIXEL TRACKING METHOD
Glacier velocity image matching Antarctica COSI-corr
2019/2/28
Glacier movement is a crucial factor for assessing cryospheric climate change. Traditional methods of field surveys for studying glacier movement and velocity are often not possible owing to inaccessi...
SYNOPTIC OBSERVATIONS OF CALVING EVENTS IN ANTARCTICA USING SPACEBORNE IMAGES
Antarctica Calving Optical Images Rifts Icebergs
2019/2/28
Iceberg calving is the detachment of ice from ice shelves or glaciers. Although calving is a natural phenomenon, an abnormal rate of calving can be a threat to ice shelves. Some of the events were so ...

2018/5/15
Models based on physical principles or semi-empirical parameterizations have used to compute the firn density, which is essential for the study of surface processes in the Antarctic ice sheet. However...
Some Antarctic fish living in the planet’s coldest waters are able to cope with the stress of rising carbon dioxide levels in the ocean. They can even tolerate slightly warmer waters. But they can’t d...

Intensifying Winds Increase East Antarctica’s Contribution Sea Level Rise
2017/11/23
Totten Glacier, the largest glacier in East Antarctica, is being melted from below by warm water that reaches the ice when winds over the ocean are strong — a cause for concern because the glacier hol...
