Bridge, the Ocean Sciences Education Teacher Resource Center, is a growing collection of on-line marine education resources. It provides educators with accurate, useful, content-correct and content-current marine and data information on global, national, and regional marine science topics, and gives researchers a contact point for educational outreach. The Resource Pavilion provides links to lesson plans and curriculum units for K-12 classrooms, while the Data Port section provides links to on-line data sets, including tips on how to use these data in the classroom. Specific classroom activities using data are detailed and updated on a monthly basis. A communication section provides access to listservs and ask-a-scientist services. Ocean science information sites are linked by discipline or topic, including biology, chemistry, physics, marine geology, ecology, atmopshere, and human activities. Current on-line expeditions and event-specific activities are highlighted on the front page.
