The long-term objective of PolarTREC teacher Lesley Urasky's expedition research in Antarctica (Glacial History in Antarctica) is to determine the rate at which glaciers have receded since the Last Glacial Maximum. This lesson is designed to give students an understanding of the Last Glacial Maximum, the climatic conditions that lead to glacial periods, and how the rate of glacial
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

IPY marks the beginning of a sustained effort to understand large-scale environmental change in Earth's polar regions, which have major societal and economic impacts, and to advance new scientific frontiers, from the molecular to the planetary scale. NASA brings a unique perspective to IPY, which will focus on five themes: 1) NASA explores scientific frontiers in Earth's polar regions.; 2)
