Coastal lakes are vulnerable to European impact, yet little is known about how they have been altered in the last 200 years. For example: Are blue-green algal blooms a natural occurrence in coastal lakes? How long have freshwater lakes been isolated from the ocean? Preliminary results indicate that, at key sites, blue-green algae were more abundant before European settlement and that coastal lakes thought to be permanently fresh have been exposed to the ocean within the past 200 years. By documenting change at representative sites, the project will identify which lake types are most vulnerable to impact. Results from the project will ensure that costly restoration efforts are not misplaced.

沿海湖泊容易受到欧洲的影响，但人们对它们在过去200年中的变化知之甚少。例如：蓝绿色藻华是沿海湖泊的自然现象吗？淡水湖与海洋隔绝多久了？初步结果表明，在关键地点，欧洲人定居之前蓝绿藻更为丰富，过去200年来，被认为是永久新鲜的沿海湖泊暴露在海洋中。通过记录代表性地点的变化，该项目将确定哪些湖泊类型最容易受到影响。该项目的结果将确保昂贵的恢复工作不会错位。
