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.

项目摘要（请参阅说明）： 用于有害藻华（HAB）检测的有害藻华（HAB）检测的泊位技术的出现促进了尚未在传统的海上调查模式下避免我们的关键开花过程的机会主义和自适应抽样。我们建议使用来自环境样品处理器（ESP）系泊设备的数据流在缅因州海湾两种类型的HAB的关键阶段中动员快速响应调查：Alexandrium Fundyense和Pseudo-Nitzschia spp。对于A. fundyense而言，抽样将集中在花朵下降上，因为终止这些花朵的机制在该领域尚未记录下来。这 伪nitzschia spp的动力学。在该地区仍未表现出很大的特征，因此，快速响应采样将在开始，发育和下降的各个阶段中。 实验室实验将使用从缅因州海湾收集的伪nitzschia分离株进行，以衡量其对环境条件的重要率和依赖性。从现场和实验室研究中获得的知识将纳入Bloom动力学模型，以提高预测能力。
