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.
On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards, ecology and other subjects with direct applications to the challenges facing humanity.
Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.
