Description:

The sea floor is mapped for a variety of environmental and commercial reasons, including marine and coastal resource management, navigational charting, and oil and gas exploration. This video segment shows how geologists aboard a research vessel employ air guns and an array of listening devices to create a profile of subsurface rock layers. They hope to use the specialized maps they create to learn more about what is driving the western part of the North American plate to split apart. The segment is two minutes forty-three seconds in length. A background essay and discussion questions are included.
