Mountains in the Sea
In this 6-7 day investigation, students begin with an introduction to seamounts that are present in the Gulf of Alaska. They learn how seamounts were formed and look at a bathymetric map of a seamount. In Activity 3A, students explore sea floor mapping techniques as they participate in an activity to create a map of a sea feature they have molded out of clay. In Activity 3B, students watch a short animated presentation, “Who cares about Sea Floor Mapping?” then create a model of a seamount found in Alaska. They use pre-sonar techniques to collect data and create a graph of their seamount using Excel.
