Writing in July 2010 when the eastern U.S. has been having one heat wave after another, it is easy to forget the winter just past, but winter 2009/10 was one of record snow in much of the mid-Atlantic region and very cold conditions across eastern North America. There was also widespread cold and snow in northwestern Europe.  At the time, as record snowfall hit Washington D.C., this was a big deal much exploited by climate deniers and others to ridicule global warming and climate science.

 The Argon Geochronology for the Earth Sciences (AGES) lab is located at Columbia's Lamont-Doherty Earth Observatory along the Palisades Parkway in Rockland County, New York. Our lab measures Argon isotope compositions and concentrations, mainly of single mineral grains, on a VG5400 noble gas mass spectrometer to determine the age of mineral formation. Our research subjects include paleocllmate provenance studies, volcanoes and deep earth time.

In collaboration with colleagues at Teachers College, Lamont scientists developed the Where Are We? software and associated curriculum materials to help elementary school childre

This project will synthesize existing knowledge and articulate unanswered questions in critical areas of research on cognition and learning relevant to the Geosciences.

 Two questions about learning that are central to, and characteristic of, geoscience education are: 1)How do people learn by direct observation of Nature in the field?

 This project will develop an integrated ice imaging system capable of measuring in detail both the ice surface and the ice bed. TheicePod system will be installed and operated on New York Air National Guard LC-130 aircraft during routine and targeted missions across Antarctica and Greenland as a shared community research facility providing data to scientists and educators globally. The fundamental data sets produced by the icePod system are necessary to support the development of accurate ice sheet models to predict sea level rise. The icePod system will consist of a suite of imaging sensors mounted in an external pod carried on New York Air National Guard LC-130’s to map the surface and subsurface ice topography of ice sheets, ice streams and outlet glaciers. 

Students often wonder how local planning issues can be of concern to them. They don't own property, they don't pay property taxes, most don't yet vote...isn't this someone elses issue? The truth is this issue is very much connected to young people. The P.L.U.S. program is designed to show students why, and how to take advantage of this connection to offer their input.  Students work in teams with students from other schools in their community to examine important land planning questions.

Scientists from several nations are working together to launch a flagship program to explore a major mountain range buried by a large continental ice sheet and bounded by numerous subglacial lakes.

Using geophysical instruments, GAMBIT will peal back more than 600 meters of ice to explore the last hidden mountain range on Earth.
