New research shows that the Larsen C ice shelf—the fourth largest ice shelf in Antarctica—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.
An international collaboration will study the wasting of the Thwaites glacier, which already accounts for around 4 percent of current global sea-level rise, and could collapse within decades or centuries.
Polar scientists Marco Tedesco and Robin Bell provide a primer on how climate change will impact our coastlines.
Lamont’s Robin Bell is living proof of the importance of encouraging young women to study STEM disciplines. Her breakthrough research, fueled by passionate intellectual curiosity, has been critical to understanding our planet.
On January 31 at 1:00 p.m. EST, Lamont-Doherty’s Hugh Ducklow and his colleagues will use National Science Foundation social media to discuss their research on Antarctic ecology.
A new study shows that even minor deterioration of ice shelves can instantaneously hasten the decline 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…. read more
In the first such continent-wide survey, scientists have found extensive drainages of meltwater flowing over parts of Antarctica’s ice during the brief summer. Many of the newly mapped drainages are not new, but the fact they exist at all is significant; they appear to proliferate with small upswings in temperature, so warming projected for this century could quickly magnify their influence on sea level.
