文章题目甲藻属的分布调查。2007年7月，在爱尔兰南海岸的沿海沃茨进行了一次调查。尖齿甲藻作为亚表层存在，含有高达55，000个细胞L-1。该群体具有高百分比的活细胞（平均值：89%;中位数：94%; n = 24），具有高特异性分裂率（类似于0.55 d（-1））。该层约5米厚，并不符合荧光最大值，并作为一个补丁的水平尺寸小于10公里x7公里。结合高垂直分辨率采样方法使用的常规和拖曳式起伏CTD都显示，甲藻斑块以与海岸流相似的速度和方向移动，海岸流以海岸急流的形式平行于海岸，速度约为6.5-7 km/天（-1）。沿海射流中有害物种种群的沿岸运输对监测方案和预测模型的影响进行了讨论。(C)2011 Elsevier B.

An investigation into the distribution of Dinophysis spp. in coastal waters off the south coast of Ireland was carried out in July 2007. Dinophysis acuta was present as a sub surface layer containing up to 55,000 cells L-1. The population had a high percentage of viable cells (mean: 89%; median: 94%; n = 24) with a high specific division rate (similar to 0.55 d(-1)). The layer, of approximately 5 m thickness, did not coincide with the fluorescence maximum and was present as a patch of horizontal dimension less than 10 km x 7 km. Both conventional and towed undulating CTD used in conjunction with high vertical resolution sampling methods showed the patch of Dinophysis to move with a similar speed and direction as the coastal flow, which ran parallel to the coast in the form of a coastal jet with speed of the order of 6.5-7 km day(-1). The implications of the alongshore transport of populations of harmful species in coastal jets for monitoring programmes and predictive models are discussed. (C) 2011 Elsevier B.V.
