Describes the Waikiki Aquarium, one of the oldest aquaria in the United States. After a brief history of the aquarium, some of the outstanding displays are described. In addition, some of the current research projects and discoveries in marine biology at the aquarium are discussed. Finally, the aquarium's educational programs are described. (BB)

Discusses the effects of radioactive wastes on marine communities, with particular reference to the fitness of populations and the need for field and laboratory studies to provide evidence of ecological change. (JR)

This unit is designed to introduce the marine environment to those with little or no previous related background. Students define the marine environment, participate in group discussions, view movies, investigate oil spills, and write environmental impact statements. The first three sessions are designed to take three hours with the composition of…
