Mapping Land Claimed by Sea Level Rise
Understanding how coastal areas changed as the ocean rose in the past could help communities protect themselves from storm surge flooding in the future as the oceans warm and sea levels rise.

Sounds of Seismology
Lamont-Doherty Earth Observatory scientist Ben Holtzman grew up discovering science through interactive exhibits in San Francisco’s Exploratorium and now provides a similar experience for others. Holtzman designs immersive shows that allow people to experience what earthquakes and seismic waves look and sound like as they move through and around the Earth. On Monday, November 17th…

Seismic Stomp
Lamont-Doherty Earth Observatory graduate student Natalie Accardo recently returned from Tanzania and Malawi, where she installed seismic instruments in both countries alongside Lamont seismologists Donna Shillington and Jim Gaherty. Natalie produced this video, which shows the scientists and their Tanzanian colleagues conducting a “stomp test” at one of their sites in the Tanzanian village of…

The R/V Marcus G. Langseth: Ocean Explorer
The Marcus G. Langseth, a research vessel operated by Lamont-Doherty Earth Observatory, traverses the world’s oceans conducting marine seismic studies that contribute to new understanding of Earth systems. The ship typically spends half the year or more on research expeditions led by Lamont-Doherty scientists and colleagues from other research institutes.

A Library of Giant Landslides
A new method for detecting big landslides is allowing scientists to understand the dynamics of these elusive events almost instantly, without traipsing to remote mountains or scrambling up rugged peaks months, or even years, later. In a recent study in the journal Science, Göran Ekström and Colin Stark, geophysicists at Columbia University’s Lamont-Doherty Earth Observatory,…

Recovering ‘Sea Spiders’ and Heading Home
The NoMelt project is more than just a seismic experiment; it also has an important magnetotelluric (MT) component. MT instruments measure natural magnetic and electric fields on the seafloor, allowing scientists to estimate the electrical conductivity of the underlying rocks. Conductivity is highly sensitive to tiny amounts of water and molten rock within the upper…

Santa Comes Bearing an OBS
Recovering OBS instruments from the ocean floor is always a tricky business, especially in our case; these instruments have been sitting beneath more than 3.5 miles of water for over a year. With cold, tired batteries powering the instruments’ acoustic transponders, communicating with them through miles of ocean currents amounts to a whispered conversation on…
On Saturday, October 17, 2026 from 10am to 4pm, Lamont-Doherty Earth Observatory Open House—our biggest, best science fun and discovery event of the year—will take place on our beautiful campus in Palisades, NY. Mark your calendar and join us for this free, family-friendly celebration of science! RSVP Today!
