原位观测，包括长期停泊的气象和海洋测量和多年的海湾范围内的船舶调查数据被用来量化年际变化的表面风，河流径流，水文条件在缅因州在2002-2011年夏季。累积上升流指数表明，上升流（下降流）有利的风条件是最持久的2010年（2005年）在10年的研究期间。2005年河流流量最高，径流高峰出现在2010年4月上旬，而不是在其他年份的4月下旬至5月中旬。停泊时间序列显示，2010年夏季沿海水温比平均值高0.5-2 °C，比2004年平均值低约2 °C。2010年4月的沿海盐度是10年研究期间最低的。这两个系泊声学多普勒海流剖面仪（ADCP）的电流测量和动态高度/地转速度计算的基础上，海湾范围内的船舶调查数据显示，2010年5月至6月有一个最弱的沿岸运输在西部的缅因州在10年的研究期间，可能与入侵的温暖的斜坡水和新鲜的比平常的斯科舍陆架水。比较沿岸流麻痹性贝类中毒（PSP）关闭地图产生的A。fundyense水华表明沿岸迁移与下游毒性程度之间存在联系。
In situ observations including long-term moored meteorological and oceanographic measurements and multi-year gulf-wide ship survey data are used to quantify interannual variability of surface wind, river runoff, and hydrographic conditions in the Gulf of Maine during summers 2002–2011. The cumulative upwelling index shows that upwelling (downwelling)-favorable wind conditions were most persistent in 2010 (2005) over the 10-year study period. River discharge was highest in 2005; peak runoff occurred in early April in 2010 as opposed to late April to middle May in other years. Moored time series show that coastal water temperature was 0.5–2 °C warmer than average in summer 2010, and about 2 °C colder than average in 2004. Coastal salinity in April 2010 was the lowest in the 10-year study period. Both moored Acoustic Doppler Current Profiler (ADCP) current measurements and dynamic height/geostrophic velocity calculations based on gulf-wide ship survey data show May–June 2010 had one of the weakest alongshore transports in the western Gulf of Maine during the 10-year study period, likely associated with intrusions of warm slope water and fresher-than-usual Scotian Shelf water. Comparisons of coastal currents to the Paralytic Shellfish Poisoning (PSP) closure maps resulting from A. fundyense blooms suggest a linkage between alongshore transport and the downstream extent of toxicity.
