        Collecting Data Below the Earth's Surface

        Underwater surfaces and subsurfaces are mapped for environmental and commercial reasons, including marine and coastal resource management, navigational charting, and oil and gas exploration. In this video segment adapted from Discovering Women, geologists employ special acoustic devices to learn what lies beneath the water...and deeper still. 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.
