Explore the Arctic Ocean With ‘IceTracker’

This week, we are launching a test of “IceTracker”—a tool that allows users to see the trajectories of Arctic sea ice forward or backward from any day between 1981 and 2012, as well as sea-ice speed, air temperature, water depth and the age of the sea ice.

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.

Role-Reversal (and Some Fun) at AGU

Francesco Fiondella is normally behind the scenes writing web stories, developing audio slideshows and videos for the International Research Institute for Climate and Society (IRI). But at this year’s annual American Geophysical Union (AGU), the tables were turned for a brief moment. He was video ambushed by climate scientist Andrew Robertson and forced to explain… read more

Clues from Last Ice Age May Hint at Drying Ahead for Some Regions

In the spectacular collapse of ice sheets as the last ice age ended about 18,000 years ago scientists hope to find clues for what regions may grow drier from human caused global warming. In a talk Thursday at the American Geophysical Union’s annual meeting, Aaron Putnam, a postdoctoral scholar at Lamont-Doherty Earth Observatory, painted a picture of earth’s dramatic transformation as seen in climate records extracted from ancient cave formations, ice cores, lake shorelines and glacial moraines.

Huge Landslide Linked to Glacier Surge in Tajikstan’s Pamir Mountains

Glaciers advance in colder temperatures, but sometimes a big rock avalanche can also make a glacier grow, new research results presented at the American Geophysical Union’s annual meeting suggests.

Tree Rings and Teachable Moments

Nicole Davi, a postdoctoral scientist at the International Research Institute for Climate and Society and the Lamont Doherty Earth Observatory, thinks tree rings are an ideal way to motivate students to collect and analyze data as well as to learn about climate change.
