摘要

The ocean is a cornerstone of southern Californias environment, culture, and economy. Its complex ecosystem features a unique diversity of plants, invertebrates, fish, birds, and marine mammals. Southern California is also home to 21 million people, and its coastal waters serve as a repository for the pollutants produced by human activities. As local and national attitudes changed and concerns about natural resource protection grew through the 1960s, the resulting flurry of environmental legislative activity included passage of the federal Clean Water Act (CWA) in 1972. Since the CWA became law 40 years ago, tremendous effort has been devoted to managing and monitoring waste discharges and regional conditions in the southern California's coastal ocean. Even so, there has not been an integrated assessment of how ocean conditions have changed over that time period. This report summarizes a collaborative effort to assess historical data, the current status, and ongoing challenges to the integrity of the regions marine environment. By addressing several critical questions about the core CWA goals, it intends both to synthesize knowledge of the early environmental pioneers and to guide those who follow in their footsteps.
