This 1 hour webinar conducted by PolarTREC teacher Glenn Clark studying the Totten Glacier System in Antarctica. Glenn focuses on the shipboard science activities to understand the marine ecosystem and glacier systems of east Antarctica.
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
