Upcoming Scientific Fieldwork: 2017 and Beyond

On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards, ecology and other subjects with direct applications to the challenges facing humanity.

Research engineer Ted Koczynski explains how rock surfaces representing the rock bed of a glacier put pressure on a block of ice from each side as the ice is pushed downward in the new cryogenic deformation apparatus. Depending on the configuration, sensors throughout the device can measure friction, viscosity and anelasticity. Image: Lamont-Doherty Earth Observatory.

Crushing Ice to Learn About Glaciers & Icy Moons

To understand how quickly ice from glaciers can raise sea level or how moons far across the solar system evolved to hold vast, ice-covered oceans, we need to be able to measure the forces at work. A new instrument designed and built at Lamont does just that.

The Otherworldly and Elusive Life Beneath Antarctica’s Ice

While renowned for the penguins, Antarctica is perhaps equally well known for what it doesn’t have: basically, anything else. But scientist Steven Chown says the view that the icy continent lacks life is “simply not true.”

Glacial Earthquakes May Help Forecast Sea-Level Rise

Glacial earthquakes are produced as massive ice chunks fall off the fronts of advancing glaciers into the ocean. A new study of the quakes’ mechanics may give scientists a way to measure ice loss remotely and refine predictions of sea-level rise.

Science, Creativity and Isopods

It’s near midnight and Lamont-Doherty Earth Observatory researchers Andy Juhl and Craig Aumack, and Arizona State’s Kyle Kinzler are gathered around a table in their lab at the Barrow Arctic Research Consortium discussing the best way to catch an isopod.

Svalbard is an archipelago in the Arctic, constituting the northernmost part of Norway. The archipelago features an Arctic climate, although with significantly higher temperatures than other areas at the same latitude. Sixty percent of the archipelago is glacier, and the islands feature many mountains and fjords - Photo by Woodwalker.

Arctic Archipelago: Ground Zero For Climate Change

Summer temperatures on the archipelago of Svalbard, 400 miles north of Norway, are now higher than at any other period in the last 1,800 years, according to a new study in the journal Geology.
