This resource features an award winning, student produced documentary film that fulfills the National Oceanic and Atmospheric Administration's obligations for the National Historic Preservation Act. Users can download movies or short movie clips that describe the first studies of the fur seal in the Pribilofs by Henry Wood Elliot, including historical, environmental, and economic policies that may have saved the seal from extinction.
The poles are fascinating, partly because they are such difficult places to visit, work and live. They still guard many mysteries that we'd like to unravel, including the survival of polar animals, the history of ancient peoples, and the understanding of Earth's climate.

This course addresses the design of tribological systems: the interfaces between two or more bodies in relative motion. Fundamental topics include: geometric, chemical, and physical characterization of surfaces; friction and wear mechanisms for metals, polymers, and ceramics, including abrasive wear, delamination theory, tool wear, erosive wear, wear of polymers and composites; and boundary lubrication and solid-film lubrication. The course also considers the relationship between nano-tribology and macro-tribology, rolling contacts, tribological problems in magnetic recording and electrical contacts, and monitoring and diagnosis of friction and wear. Case studies are used to illustrate key points.
