New App: Explore Ice & Sea Level Changes
Explore the oceans, ice sheets, and economic risks posed by flooding and sea level rise around the world with the new Polar Explorer app created by scientists at Lamont. The free map-based app shows how precipitation, temperatures and the ice have changed over time.

Detecting Landslides from a Few Seismic Wiggles
North America's largest landslide in 35 years – 200 million tons of rock crashing into Alaska's Taan Fiord – might have gone unnoticed but for seismologists at Lamont. Colin Stark and Göran Ekström explain how they detect the signature of landslides and discern their size, direction, velocity and acceleration, and the precise time they struck.

Greenland's Glacier Retreat Rate Fastest in 9,500 Years
Over the last century, glaciers in Greenland have been retreating quickly – at a rate at least twice as fast as any other time in the past 9,500 years, according to a new study. Lamont's Billy D'Andrea explains how he and colleagues used sediment cores from a glacier-fed lake to uncover the region's history of glacier growth and loss.

Study Undercuts Idea of a Global 'Medieval Warm Period'
Greenland wasn't that warm when the Vikings arrived after all, a new study finds. Glacier evidence suggests the island was already cold and climate played little role in the colony's mysterious demise. The study, led by Lamont's Nicolás Young and Joerg Schaefer, adds to evidence that the Medieval Warm Period might not have been global.

Teaming Up with Google to Bring the Seafloor into Focus
Lamont scientists are giving Google Earth a clearer view of the ocean floor. Vicki Ferrini, Suzanne Carbotte and colleagues have been turning data from hundreds of research cruises into accessible seafloor maps with resolutions down to 25 meters, continuing a long tradition of ocean data collection and mapping at Lamont.
