Santa Monica Bay is an open coastal embayment located directly seaward of Los Angeles, California. The Bay provides vital economic value through its water-dependent activities, such as swimming, diving, boating, and fishing. An increase from 100,000 residents in 1900 to 10 million in 2000 has imposed numerous environmental stressors on the Bay, including urbanization of the watershed. Pollutant discharges into the Bay increased throughout the early part of the century, but declined following passage of the Clean Water Act in 1972. Since that time, the predominant source of pollutant inputs has changed from point sources to non-point urban runoff. To assess how present-day and historical pollution interact to affect the environmental quality of Santa Monica Bay, three organizations collaborated on a multi-disciplinary study in 1997, towards which this volume is focused. This paper details the temporal patterns of anthropogenic influence on Santa Monica Bay to provide context for the papers that follow.
圣莫尼卡湾是一个位于加利福尼亚州洛杉矶市正对着大海的开阔沿海港湾。该海湾通过其依赖水的活动,如游泳、潜水、划船和钓鱼,提供了重要的经济价值。从1900年的10万居民增加到2000年的1000万,给该海湾带来了众多环境压力,包括流域的城市化。整个世纪初,排入海湾的污染物不断增加,但在1972年《清洁水法》通过后有所下降。从那时起,污染物输入的主要来源已从点源转变为城市面源径流。为了评估当今和历史污染如何相互作用以影响圣莫尼卡湾的环境质量,三个组织于1997年合作开展了一项多学科研究,本书即围绕该研究展开。本文详细介绍了人类活动对圣莫尼卡湾影响的时间模式,为后续论文提供背景信息。
