What Is Ocean Acidification & Why Does It Matter?
Excess carbon dioxide absorbed into the oceans is starting to have profound effects on marine life, from oysters to tiny snails at the base of the food chain. Our scientists explain the changes and what they are learning about ocean acidification in the past.

Antarctica’s Ice: the Big Picture
The impacts of climate change are being felt around the world, but the changes in the polar regions have been more pronounced. The world began to take notice to these changes when an ice shelf roughly the size of Rhode Island collapsed into the ocean in 2002.

Using LiDAR to Shine a Light on Ross Ice Shelf
LiDar (Light Detection and Ranging) is a remote sensing technique that uses light to develop an elevation image of the surface of the Earth. It is sensitive enough to image small items such as seals lying on the ice surface.

Greenland Glaciers Retreating Faster than Any Time in Past 9,500 Years
A new study uses sediment cores to track the expansion and retreat of glaciers through time, and finds that they are retreating quickly and are more sensitive to temperature change than previously realized.

The Compact Efficiency of New Airborne Science
The latest team celebration is around the magnetometer data. Magnetics has evolved quite a bit over the years of geophysical sampling. Lamont scientist Robin Bell recalls when in the 1990s working on a project in West Antarctica that the magnetometer was towed on a winch ~100 meters behind the aircraft – now it is nearly…
