The microstructure of polar ice. Part I: Highlights from ice core research
Polar ice sheets play a fundamental role in Earth's climate system, by interacting actively and passively with the environment. Active interactions include the creeping flow of ice and its effects on polar geomorphology, global sea level, ocean and atmospheric circulation, and so on. Passive in...

Polar ice sheets play a fundamental role in Earth's climate system, by interacting actively and passively with the environment.
