2005年春末夏初，缅因州海湾沿岸沿着发生了一次大面积的亚历山大藻水华。为了了解水华发生和发展的物理方面，使用全海岸船舶调查和沿海观测网络的现场观测来描述该时期的沿海环流和水文特征。将这些现场观测结果与其各自的长期观测结果进行比较，发现2005年5月期间海洋状况异常：由于更多的地表加热和河流径流，沿海地区的沃茨更加温暖和新鲜;沿海洋流至少比其气候平均值强2倍。地面风也异常，表现为东北风阵发和有利于下沉流的平均条件。这些因素可能有利于更有力的沿岸运输和近岸聚集的有毒A。二〇 〇五年发现的一宗红潮。
An extensive Alexandrium fundyense bloom occurred along the coast of the Gulf of Maine in late spring and early summer 2005. To understand the physical aspects of bloom's initiation and development, in situ observations from both a coast- wide ship survey and the coastal observing network were used to characterize coastal circulation and hydrography during that time period. Comparisons between these in situ observations and their respective long- term means revealed anomalous ocean conditions during May 2005: waters were warmer and fresher coast- wide owing to more surface heating and river runoff; coastal currents were at least 2 times stronger than their climatological means. Surface winds were also anomalous in the form of both episodic bursts of northeast winds and a downwelling- favorable mean condition. These factors may have favored more vigorous along-shore transport and nearshore aggregation of toxic A. fundyense cells (a red tide) in 2005.
