elective courses in which the concepts and designs available to the world market are discussed and analyzed. Through the use of a combination of synchronous and asynchronous distance-learning technologies, the program is accessible to all students with access to an appropriate home or office computer. Applications for the MMarE's 2008-09 program are now being accepted on a rolling admissions basis for the academic year that begins September 2008.

different blend percentages. Initially the boats are fueled with a five percent blend of biodiesel. As the demonstration progresses, biodiesel blends are increased to a 10 percent (B10), followed by a 20 percent blend (B20). The Issaquah is currently running on a 20 percent (B20) blend of biodiesel. There have been no problems in the vessel's operational performance running on biodiesel so far. The Tillikum's increase to a 10 per-
cent biodiesel blend has been delayed due to sludge accumulation in the vessel's fuel purifier. Researchers at the University of Idaho -- a project partner -- are analyzing samples to determine the source of the sludge on this particular vessel. Biodiesel testing is expected to continue until February 2009. Testing results will be used to create a published document guiding the marine industry in the use of biodiesel.
The Washington State Department of Transportation (WSDOT) Ferries Division will began operating its third vessel - Klahowya - with a biodiesel fuel blend on July 19. The Klahowya will operate on a five percent blend (B5) of tallow-based biodiesel and ultra-low sulfur diesel (95 percent). Tallow-based biodiesel is made from unused beef fat left over from the rendering process. The process of converting tallow into biodiesel is similar to the process used to convert plant oils such as soy and canola into biodiesel. The Klahowya fueling is part of the Biodiesel Research and Demonstration Project - a scientific pilot test of biodiesel in the marine environment. The ferry system began the testing phase of the project in March with the fueling of the Issaquah using a five percent blend of soy-based biodiesel. In April, the vessel Tillikum began running on a five percent blend of canola-based biodiesel. In addition to testing different types of biodiesel, the ferry system is testing
