Harmful algal blooms, commonly called `red tides` or HABs, are a serious economic and public health problem throughout the world. In the U.S., the most serious HAB problem is paralytic shellfish poisoning (PSP), a potentially fatal neurological disorder caused by human ingestion of shellfish that accumulate toxins as they feed on dinoflagellates of the genus Alexandrium. These organisms cause human illness and death due to PSP, repeated shellfish harvest quarantines, and the mortality of fish and marine mammals. This phenomenon, which affects thousands of miles of U.S. coastline and numerous fisheries resources, has expanded dramatically in the last two decades, especially in the Gulf of Maine. The ECOHAB-GOM addresses several fundamental issues regarding Alexandrium blooms in the Gulf of Maine: 1) the source of the Alexandrium cells that appear in the fresh water plumes in the western Maine coastal current (WMCC); 2) Alexandrium cell distribution and dynamics in the eastern Maine coastal current (EMCC); and 3) linkages among blooms in the WMCC, the EMCC and on Georges Bank. Utilizing a combination of numerical modeling, hydrographic, chemical, and biological measurements, moored and drifting current measurements, and satellite imagery, we will characterize the structure, variability and autecology of the major Alexandrium habitats in the Gulf of Maine.

有害藻华，通常称为“赤潮”或HAB，是全世界严重的经济和公共卫生问题。在美国，最严重的HAB问题是麻痹性贝类中毒（PSP），这是一种潜在致命的神经系统疾病，由人类摄入以亚历山大藻属甲藻为食时积累毒素的贝类引起。这些生物体因PSP、反复的贝类收获检疫以及鱼类和海洋哺乳动物的死亡而导致人类疾病和死亡。 这种现象影响了数千英里的美国海岸线和众多的渔业资源，在过去二十年中急剧扩大，特别是在缅因湾。 ECOHAB-GOM 解决了有关缅因湾亚历山大藻华的几个基本问​​题：1) 出现在缅因州西部沿海流 (WMCC) 淡水羽流中的亚历山大藻细胞的来源； 2）缅因州东部沿岸流（EMCC）中亚历山大藻细胞的分布和动态； 3) WMCC、EMCC 和 Georges Bank 中的绽放之间的联系。综合利用数值模型、水文学、化学和生物测量、系泊和漂流测量以及卫星图像，我们将描述缅因湾主要亚历山大藻栖息地的结构、变异性和自生生态。
