One of the most important indicators of our warming climate is the extent and thickness of polar sea ice. Currently satellites measure the extent of polar sea ice but it takes more sophisticated equipment aboard a low-flying plane to actually measure the thickness of sea ice. This lesson will show students how this is done.
This series of three labs challenges students to think about the role of plankton in different ecosystems and waterways in the world. By modeling the research methods of scientists on the Healy icebreaker, students can conduct a small-scale change study to examine reproductive behavior of an isolated type of local plankton.
