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.
Vicki Ferrini has spent a lot of time working on mapping the ocean floor, and now she’s sailing in the South Pacific to get a closer look.
On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards and ecology, and their practical applications to modern problems. Below, a list of expeditions in rough chronological order. Work in and around New York City and the U.S. Northeast is listed separately toward bottom. Unless otherwise stated, projects originate with… read more
Dennis E. Hayes, a marine geophysicist who advanced mapping of the world’s ocean floors, died at his home in New York City on Aug. 6. He was 76.
The formation of the slender land bridge that joins South America and North America was a pivotal event in earth’s history. At its narrowest along the isthmus of Panama, it changed not just the world map, but the circulation of oceans, the course of biologic evolution, and global climate. Cornelia Class, a geochemist at Columbia University’s Lamont-Doherty Earth Observatory, and Esteban Gazel, a Lamont adjunct researcher now based at Virginia Tech, are looking into a key factor: the Galápagos Plume.
Earth Institute field researchers study the planet on every continent and ocean. Projects are aimed at understanding the fundamental dynamics of climate, geology, ecology, human history and more. Here is a partial list of upcoming expeditions.
In the Arabian peninsula nation of Oman, geologists are studying the Hajar mountains–a range containing rocks that have been thrust up from the deep earth. Accessible to humans in only a few places on earth, these kinds of rocks offer clues to the planet’s deep history–and possible ways that natural processes may be harnessed to combat modern climate change.
