Where Continents Divide, and Rocks Rise from the Deep
Along the Woodlark Rift in eastern Papua New Guinea, continents are breaking apart, “like a snake opening its mouth.” Geologic processes that are still a mystery are actively stretching the crust and pushing huge masses of rock, formed under immense pressures as deep as 100 kilometers below, to the surface.

Natural Disasters: The Upside
Floods, volcanoes, earthquakes–really, very little good news comes out of this sort of thing. Maybe the occasional feel-good story about, say, a child miraculously dug from the rubble days later, tired but unharmed and in good spirits, having survived on a cache of crackers and Coke. Actually, says John Mutter, an Earth Institute professor of sustainability studies, disasters can sometimes…

Under the Dead Sea, Warnings on Climate and Earthquakes
An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period analogous to scenarios for climate change in coming decades. With nations in the volatile region already running short on water, the finding could be a…

Seismometer Puts Earthquakes Online at Kent School
A well-traveled seismometer sits tucked inside a concrete chamber behind the Kent School chapel in Northwest Connecticut, recording earthquakes. It got here by chance.

Jumping Ship
As we finally reached our prime target area, it was time for me to leave the ship and return home. Despite initial struggles on navigating the Brahmaputra River, we have worked together with the ship’s crew and pilots for a successful method. And now as I leave with many new friends, the best data is…

Cruising up the Brahmaputra
Rejoining the ship, we sailed up the Padma and Jamuna (Brahmaputra) Rivers. Hurrying to our primary area with the help of pilots, we finally collected good seismic data.

Excursion to Dhaka
Finishing up in the muddy rivers of NE Bangladesh, we headed downstream to switch to the mighty Brahmaputra River system. However, on the way down I had to jump ship to go into traffic-clogged Dhaka for some meetings before rejoining her on the Padma, the name of the combined Ganges and Brahmaputra Rivers.

To Meghalaya and back
From our return to Jamalganj, we headed east searching for a river to carry us up to the Indian border across the Dauki Fault. Along the way, we celebrated Steve Goodbred’s birthday. However, even the biggest of the rivers proved too shallow for our boat. We switched to the

Return to Jamalganj
We have been sailing along collecting data, but so far the data quality is poor due to shallow gas in the sediments. We thought we might have some problems with gas, but the problem is more widespread than we expected. We are now out of the inland summer lake where we met the boat and…
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
