PROJECT SUMMARY (See instructions): The advent of moored technologies for harmful algal bloom (HAB) detection with real-time telemetry facilitates opportunistic and adaptive sampling of key bloom processes that have as yet evaded us in traditional seagoing survey mode. We propose to use data streams from Environmental Sample Processor (ESP) moorings to mobilize rapid-response surveys during key phases of two types of HABs in the Gulf of Maine: Alexandrium fundyense and Pseudo-nitzschia spp. For A. fundyense, sampling will focus on bloom decline, as the mechanisms that terminate these blooms are as yet undocumented in the field. The dynamics of Pseudo-nitzschia spp. remain largely uncharacterized in this region, and rapid response sampling will accordingly be targeted amongst the various phases of initiation, development, and decline. Laboratory experiments will be conducted with Pseudo-nitzschia isolates collected from the Gulf of Maine to measure their vital rates and dependencies on environmental conditions. Knowledge gained from both field and laboratory studies will be incorporated into models of bloom dynamics to improve predictive capabilities.

项目总结（见说明）： 系泊技术的出现，有害藻华（HAB）检测与实时遥测促进机会主义和适应性采样的关键盛开的过程中，我们还逃避了传统的海上调查模式。我们建议使用环境样品处理器（ESP）系泊的数据流，以动员快速响应调查的关键阶段的两种类型的有害生物在缅因州的海湾：亚历山大fundyense和伪菱形藻。对于. Fundyense，采样将集中在水华下降，因为终止这些水华的机制在该领域尚未记录。的 拟菱形藻种群动态在这一地区，大部分情况下尚未确定，因此，快速反应取样将在启动、发展和衰退的各个阶段进行。 实验室实验将进行与伪菱形藻分离收集自缅因州海湾，以测量其生命率和对环境条件的依赖性。从实地和实验室研究中获得的知识将被纳入水华动态模型，以提高预测能力。
