This lesson plan is designed to teach students about the importance of the benthic community in the shallow portions of the Arctic and how climate change may affect their respiration. One of the dominant benthic animals in the Arctic, the bivalve Macoma sp., is an important food source for higher trophic level organisms such as walrus and Spectacled Eiders
This lesson plan is designed to teach students about benthic biodiversity in the Arctic by analyzing data from the Distributed Biological Observatory (DBO). Although you can’t see them from the surface, the organisms found on the ocean floor are important indicators of ecosystem health and provide information about productivity. Students will explore sites throughout the Bering and Chukchi Seas
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
