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...

2018/5/11
Snow/ice accumulation and melt, as a vital part of hydrological processes, is close related with vegetation activities. Taking Namco basin for example, based on multisource remote sensing data and the...
Extreme melt season leads to decade-long ecosystem changes in Antarctica's Dry Valleys（图）
Extreme melt season decade-long ecosystem changes Antarctica Dry Valleys
2017/9/4
An abnormal season of intense glacial melt in 2002 triggered multiple distinct changes in the physical and biological characteristics of Antarctica's McMurdo Dry Valleys over the ensuing decade, new r...

Arctic melt ponds meltwater clogs ice pores
2017/2/16
When spring comes to the Arctic, the breakup of the cold winter ice sheets starts at the surface with the formation of melt ponds. These pools of melted snow and ice darken the surface of the ice, inc...
Researchers from MIT, Princeton University, and elsewhere have developed a new technique to monitor the seasonal changes in Greenland’s ice sheet, using seismic vibrations generated by crashing ocean ...
Evolution of the volcanic plumbing systemof Alicudi (Aeolian Islands - Italy): evidence from fluid and melt inclusionsin quartz xenoliths
Aeolian Islands fluid inclusions crustal xenoliths homogenisation temperature magma plumbing system
2015/9/15
Quartz-rich xenoliths in lavas (basalts to andesites; 90-30 ka) from Alicudi contain abundant melt and fluid inclusions. Two generations of CO2-rich fluid inclusions are present in quartz-rich xenolit...
