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
PolarTREC teacher Paula Dell accompanied researcher Kristin O’Brien’s team to Palmer Station in Antarctica for two
months in 2011 to conduct research on antarctic fishes. This article describes their expedition, their evolving collaboration and includes interviews with both Paula Dell and PolarTREC project manager, Janet Warburton.
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
