Chasing Ghengis Khan
Once you, as an outsider, spend considerable time in Mongolia, especially during Naadam and especially in the open Gobi steppe with people who still live as their ancestors did centuries ago, you will also begin to chase Chinggis Khaan.

In the Woods Listening for the Langseth
Our sensors record the same seismic signals as the ocean bottom seismometers the R/V Oceanus deployed, and we will combine the data later. They can detect R/V Langseth signals up to 100 miles inland! This is something extraordinary, and difficult to believe until seen.

Investigating the World’s Oceans, Pole to Pole and Deep Below the Bottom
Watch a slide show featuring ongoing research by scientists at Columbia University’s Lamont-Doherty Earth Observatory, whose work around the globe is key to understanding past changes in the oceans and what is going on today.

Water Samples and Wildlife
After a day of coring on Tuesday, we decided to give our arms and backs a rest and collect water and plant samples. We take these samples so that we can characterize the chemical signatures of each plant type, and water from different parts of the system. Then, we can recognize those same signatures in…

Passing Ships in the Night
By Helene Carton As part of our study of the Juan de Fuca plate from its birth at the mid-ocean ridge to its recycling at the Cascadia subduction zone, the R/V Oceanus has the task of conducting Ocean Bottom Seismometer (OBS) operations and oceanographic measurements: this is done in close coordination with the R/V Langseth,…

Deepest core yet from Imnavait Creek!
Our first day in the field was a wild success! We visited Imnavait Creek Peatland, named for the small stream that drains out of it into the Kuparuk River. We chose this location because it has the potential to be much older than many other peatland sites. During the last ice age, the area of the…

Getting There = 0.5*fun
Hello from the land of the midnight sun! We have just arrived by way of the famous Dalton Highway at Toolik Field Station, a Long Term Ecological Research site of the University of Alaska Fairbanks. We pulled up to the station just in time for dinner, a quick trip to the field station’s wood-fired sauna,…

Studying Cutting-Edge Carbon Storage Technologies
This past June, PhD candidates from Earth Institute’s Lenfest Center for Sustainable Energy Miriam Okun and Yinghuang Ji traveled to Alabama to attend Research Experience in Carbon Sequestration (RECS), an intensive 10-day program hosted by Southern Company and sponsored by the Department of Energy’s National Energy Technology Laboratory. The program allowed participants to study cutting-edge…

When the World Ended in Ice
A mile or so of glacial ice covering much of North America and plowing down from the north once terminated in the New York metropolitan area, at a front stretching roughly from exit 13 on the New Jersey Turnpike (Rahway), on across southern Staten Island, the Bensonhurst neighborhood of Brooklyn, and northeastward through Long Island. But exactly when that ice started…
The first Earth Day in 1970 ignited a movement to stop polluting our planet. Today, our scientists and experts are tackling the most pressing challenges to achieve real-world impact. This Earth Day, join us in our commitment to realizing a just and sustainable future for our planet. Visit our Earth Day website for ideas, resources, and inspiration.
