Walter Pitman, a seagoing geophysicist who spotted a crucial piece of a huge puzzle that revolutionized the earth sciences, has died.
In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean.
The paleoclimatologist and marine geologist talks about why the miles and miles of marine sediment samples in Lamont’s Core Repository are so important.
On a small volcanic island in the Indian Ocean lies a geologic enigma—a mass of pure white quartzite sandstone apparently formed on a faraway continent long ago. How did it get there?
The Corinth rift is one of the most seismically active areas in Europe. Starting this month, researchers will drill into the rift to discover its past and future.
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.
Only a few people have ever explored deep inside the seafloor canyons that President Obama just designated a national marine monument. Bill Ryan is one of them. In this podcast he describes what his team saw and learned.
Bridgit Boulahanis, a marine geophysics graduate student at Lamont-Doherty Earth Observatory, prepares to head out on her first research cruise exploring the seafloor with underwater vehicles.
A new study carried out on the floor of Pacific Ocean provides the most detailed view yet of how the earth’s mantle flows beneath the ocean’s tectonic plates.
