Have you ever wondered how polar scientists do it? How do they really know if the planet is losing vast quantities of ice anyway? You can use pictures from satellites to monitor the surface from year to year, but the vast majority of ice is hidden from view, buried beneath the surface in some of the most inhospitable and
In this one hour webinar PolarTREC teacher Tim Spuck explains his work with the NASA IceBridge Project, the largest airborne survey of Earth's polar ice ever conducted.
During Lesley Urasky’s expedition, “Glacial History in Antarctica”, the team collected rock samples which were taken back to the University of Washington to be dated using cosmogenic (exposure) dating. This method of radiometric dating measures the ratio of isotopes of Beryllium (9Be:10Be) produced by the interaction of cosmic rays with minerals in rocks. This lesson will introduce the student to
