Ecological Succession: Forest Fires to the Ocean Floor
A new study reveals that new microbes supplant the active hydrothermal vent’s microbes after the site ceases to produce thermal energy. Though more research is necessary to fully understand the regeneration process in the dormant hydrothermal vents, the study provides an additional platform for ecologists to explore how ecosystems recover from natural unbalances and how…

Ohio Quakes Probably Triggered by Disposal Well, Say Seismologists
Earthquakes that have shaken an area just outside Youngstown, Ohio, in the last nine months are likely linked to a disposal well for injecting wastewater used in the hydraulic fracturing process, say LDEO seismologists.

Holidays on the High Seas
With round-the-clock shifts, there are precious opportunities for Santa to slip onto a research ship unseen. But slip in he did, leaving treats and gifts around the R.V. Langseth to brighten our day.

Retrieving Instruments from the Deep
Over the first 22 days aboard the R/V Marcus G. Langseth, we’ve zigged and zagged our way over a 360×240 mile region of the Pacific plate, first dropping instruments to the seafloor, and then shooting airguns to them (see previous posts). The final step is to recover a subset of the instruments: 34 ocean-bottom seismometers…

Restoring Damaged Ecosystems – The Challenge of Haiti
In 2010, almost two-thirds of the world’s ecosystems were deemed degraded due to human impacts and mismanagement, but fortunately ecosystems can be restored. The Earth Institute’s work in Haiti illustrates just how complicated ecosystem restoration can be.

The Art of Sound in the Ocean
The NoMelt experiment aims to image the structure of an oceanic plate, including its deepest reaches up to 70 km beneath the seafloor. One of our primary means to do so is to create sound (acoustic) waves in the ocean from the ship, and record those waves at receivers on the seafloor, after they have…

Earth Institute Science in Spotlight
Research presented by Earth Institute scientists at the 2011 American Geophysical Union fall conference generated a lot of attention from the media. Much of it came from a press conference held to discuss findings by Steve Goldstein from the Lamont-Doherty Earth Observatory and his colleagues on the potential for future drying up of the Dead…
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
