The cold, dense water circulating under Antarctica's Filchner-Ronne Ice Shelf (FRIS) keeps under-ice melting there to a minimum, helping the ice shelf act as a regulating force against the Antarctic Ice Sheet's contribution ...

The Antarctic Ice Sheet is the largest block of ice in the world. It covers an area four times the size of China and holds more than 60% of the world's fresh water. Where the ice sheet meets the ocean, it forms floating shelves ...

Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 meters, could be more vulnerable to complete disintegration than previously thought. A new study led by British Antarctic Survey ...

Less than 500 miles from the North Pole, the Milne Fiord Epishelf Lake is a unique freshwater lake that floats atop the Arctic Ocean, held in place only by a coating of ice. The lake is dominated by single-celled organisms, ...

Below Europa's thick icy crust is a massive, global ocean where the snow floats upwards onto inverted ice peaks and submerged ravines. The bizarre underwater snow is known to occur below ice shelves on Earth, but a new study ...
