How Fast Are Ice Shelves Really Melting?

A small group of scientists and doctoral students from the University of California, Davis, recently returned from Antarctica, where they became the first group to collect turbulence measurements from an underwater glider beneath an ice shelf.

This multinational collaboration being led by the Korea Polar Research Institute, or KOPRI, was only the second time a glider has been successfully deployed underneath an ice shelf.

Melting Sea Ice May Be Speeding Nature’s Clock in the Arctic

Spring is coming sooner to some plant species in the low Arctic of Greenland, while other species are delaying their emergence amid warming winters. The changes are associated with diminishing sea ice cover, according to a study published in the journal Biology Letters and led by the University of California, Davis.

Ice Surface Melts One Step at a Time

For a solid, ice is slippery stuff, even well below its freezing point. Victorian scientist Michael Faraday discovered over 150 years ago that ice is coated with a thin layer of liquid, which both makes ice slippery and contributes to chemical reactions at the surface. Now, researchers in Germany, the U.S. and Japan have used a combination of experiments and computer modeling to show how this “quasi-liquid layer” forms as layers of the ice crystal melt.
