Shrinking Glaciers: A Chronology of Climate Change

With new data, scientists can track back what glaciers did in the past, and how it is related to climate change. This provides a link to predict what could be happening in the next 100, 200, 500 years.

The Compact Efficiency of New Airborne Science

The latest team celebration is around the magnetometer data. Magnetics has evolved quite a bit over the years of geophysical sampling. Lamont scientist Robin Bell recalls when in the 1990s working on a project in West Antarctica that the magnetometer was towed on a winch ~100 meters behind the aircraft – now it is nearly cheek to cheek with other instruments!
