Radar Reveals Meltwater’s Year-Round Life Under Greenland Ice

An improved technique developed by a graduate student at Lamont-Doherty Earth Observatory and her colleagues is making it possible to use airborne ice-penetrating radar to reveal meltwater’s life under the ice throughout the year.

Creating Earthquake Heat Maps: Temperature Spikes Leave Clues in the Rock

When a fault slips, the temperature can spike by hundreds of degrees, high enough to alter organic compounds in the rocks and leave a signature. Lamont scientists have developed methods to use those organic signatures to reconstruct past earthquakes and better understand what controls them.

Learning from Slow-Slip Earthquakes

Off the coast of New Zealand, there is an area where earthquakes can happen in slow-motion as two tectonic plates grind past one another. These slow-slip events create an ideal lab for studying fault behavior along the shallow portion of subduction zones.

State of the Arctic: Longer Melting Seasons, Thinning Sea Ice

The Arctic is warming twice as fast as the rest of the planet, and scientists are seeing the effects across ice and ecosystems. Lamont-Doherty Earth Observatory’s Marco Tedesco describes the changes underway.
