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...
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 ...
