Students will investigate the physical description and mapping of seamounts in a Gulf of Alaska chain as they discover how seamounts in the Axial-Cobb-Eikelberg-Patton chain can be mapped to facilitate their exploration with a manned submersible. They will describe major topographic features on the Patton Seamount, interpret two-dimensional topographic data, and create a three-dimensional model of landforms from two-dimensional topographic data. This hands-on activity uses online data resources and includes: focus questions, learning objectives, teaching time, audio/visual materials needed, background information, learning procedures, evaluations, extensions, as well as resources and student handouts.
