Newly analyzed drill cores taken from the bottom of Greece’s Gulf of Corinth show that sediment flow into the basin has varied dramatically over the past 500,000-plus years, as the earth passed in and out of ice ages, and humans later dominated the surrounding landscape.

On the volcanic Indian Ocean island of Anjouan, scientists are investigating a rock that apparently formed on a far-off continent.
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?
Posing as an interplanetary flight attendant in an upcoming show, researcher Christine McCarthy will lead a geological journey through the solar system.
The President’s Global Innovation Fund will provide grants to four Earth Institute research projects.
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.
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.
A 4,000-foot-high mountainside collapsed in Glacier Bay National Park this week in a massive landslide that spread debris for miles across the glacier below. Scientists at Lamont-Doherty Earth Observatory are studying it to improve understanding of landslide risks.
Imbrie, a former head of the Department of Geological Sciences, helped confirmed connections between changes in Earth’s orbit and the timing of the ice ages and was a co-founder of CLIMAP, an international effort to use sediment cores to map Earth’s climate at the height of the last ice age.
