Listen in to this radio interview on National Public Radio's program, "All Things Considered" with PolarTREC teacher Nell Herrmann. Nell describes her excitement about traveling to Antarctica and her role in a study of Antarctic seafloor organisms and their response to changes in water acidification and temperature. Nell outlines her plans for sharing the research team's findings with her students
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
