From Monterey to the Northwestern Hawaiian Islands, the United States has a coterie of marine sanctuaries and habitats that are quite rich in their diversity of marine life. Teachers will particularly appreciate the National Marine Sanctuaries Education site as it offers up a number of instructional materials for use in the classroom, including lesson plans and video clips. Much of this material can be found in the "For Teachers" area, and instructors can make use of the "West Coast Field Guide" and specialized materials on humpback whales. For those looking for more specific data, there is also an "Ocean Data" area that features GIS materials on the various marine sanctuaries, along with instructional materials that make use of satellite images. Finally, visitors can sign up to be notified via email when new materials are added to the site.
