New research shows that the Larsen C ice shelf—the fourth largest ice shelf in Antarctica, located just south of the former Larsen B shelf—experienced an unusual spike in late summer and early autumn surface melting in the years 2015 to 2017.

Scientists are sailing to remote areas of the Southern Ocean to drill cores from the bottom that they hope will contain clues to past rapid changes in the Antarctic ice, and how it may react to warming climate today.

A team of autonomous ocean robots deployed in January 2018 has carried out the first year-long observations under an Antarctic ice shelf.

Scientists have known for some time that ice shelves off West Antarctica are melting as deep, warm ocean waters eat at their undersides, but a new study shows that temperatures, and resultant melting, can vary far more than previously thought, within a time scale of a few years.

Lamont’s Robin Bell is one of the world’s leading polar investigators and has been tracking ice for thirty years. She has coordinated ten expeditions to Antarctica and Greenland. And although she took her first expedition to Antarctica back in the 1980s, there is nothing routine about her approach.

The coasts of Antarctica are ringed with ice shelves – large expanses of ice that float on the surrounding ocean and form the outermost extensions of the glaciers that cover the land behind them. A new study shows that even minor deterioration of ice shelves can instantaneously hasten the motion and loss of ice hundreds of miles landward.

Iron particles catching a ride on glacial meltwater washed out to sea are likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, according to a new study.
Microalgae, also known as phytoplankton, are plant-like marine microorganisms that form the base of the food web in many parts of the ocean. “Phytoplankton serve as food for all of the fish and animals that live there. Everything that eats is eating them ultimately,” said Kevin Arrigo, a biological oceanographer at Stanford University and lead author of the study.
