The magma that feeds volcanoes beneath Earth’s surface is a mix of solid particles, liquid melt and gas bubbles. Successfully predicting whether lava from an erupting volcano will ooze out slowly or in a sudden and potentially deadly explosion has long vexed scientists.

Researchers set out four microphones like this one in the foothills of Alaska's Brooks Range to record songbird calls over five breeding seasons. In a new study, they describe an automated tool for sifting through thousands of hours of recordings to estimate when migratory birds arrive en masse in the Arctic. (Photo credit: Heather Greaves)

In a new study, scientists describe a way to quickly sift through thousands of hours of field recordings to estimate when songbirds arrive at their Arctic breeding grounds. Their research could be applied to any dataset of animal vocalizations to understand how migratory animals are responding to climate change.

Along the walls of Oceanographer Canyon, fish dart in and out of colorful anemone gardens and sea creatures send up plumes of sand and mud as they burrow.

Lamont-Doherty Earth Observatory opens its doors for a day of free public lectures, demonstrations, and workshops for adults and children.

The Center for Climate and Life, a new research initiative based at Columbia’s Lamont-Doherty Earth Observatory, will focus on how climate change affects our access to such basic resources as food, water, shelter and energy.

The Langseth, operated by Columbia’s Lamont-Doherty Earth Observatory for the National Science Foundation, supports worldwide oceanographic research.

Sean Solomon, director of Columbia University's Lamont-Doherty Earth Observatory, has been leading NASA’s MESSENGER mission to Mercury for the last four years. MESSENGER is the first spacecraft to orbit Mercury.

Tourists flock to Italy to see Michelangelo’s David and other iconic hunks of Renaissance stone, but in a trip over spring break, a group of Columbia students got to visit rocks that have shaped the world in even more profound ways.
