PBS Online presents the Ocean Alliance's Voyage of the Odyssey, a multi-year project that is gathering baseline data on ocean health, using whales, albatrosses, and pelagic fish as environmental indicators. Students can read or listen to daily logs from the ship and track the voyage, while Science from the Field offers several video and audio reports. Be sure not to pass by the Interactive Ocean portion of the site, which offers a unique opportunity to experience some of the sights and sounds beneath the surface. The Class from the Sea section is still under construction but will offer exciting ways to interact with the voyage, including virtual teleconferencing with the ship's crew. This site is a cool multimedia resource for captivating the attention of students and also a more general audience.
