This DVD begins by looking at the characteristics common to all aquatic environments. The proram then examines the littoral, limnetic and profundal zones of freshwater lakes, the seasonal cycling of 02 and nutrients, and the difference betweeen oligotrophic and eutrophic lakes before observing how life changes along the course of rivers and explaining the ecological importance of wetlands and estuaries. The photic, aphotic, benthic and other ocean zones are then described and various marine habitats such as tide pools, kelp forests, coral reefs, open ocean and vent communities explored.
