摘要
Effects of winds, tides and river water runoff on the formation and disappearance of Alexandrium tamarense blooms in Hiroshima Bay, Japan were investigated using data from March to June of 1992–1998. The north wind at the initial growth phase of A. tamarense appeared to have prevented bloom formation by dispersing the organism offshore and/or through turbulent mixing. The decrease in the cell density at the end of the blooms was significantly affected by tidal mixing, indicating that the turbulent mixing induced by tidal excursions may be one of the factors terminating the bloom. Box model analyses applied to the data collected from the observations in 1996 and 1997 showed that river water runoff apparently dispersed the bloom, implying that stratification of the water column due to river water runoff is not necessary for the bloom formation. In conclusion, calm conditions with less wind and tidal mixing along with less river water runoff are considered to be important for the formation of the A. tamarense bloom in Hiroshima Bay, Japan.

利用1992 - 1998年3 - 6月的数据，调查了日本广岛湾风，潮和河水径流对塔玛亚历山大藻（Alexandrium tamarense）花芽形成和消失的影响。在塔玛亚历山大藻的初始生长阶段，北风似乎通过分散海洋生物体和/或通过湍流混合防止了花的形成。潮汐混合显着影响花期结束时细胞密度的降低，表明由潮汐漂移引起的湍流混合可能是终止开花的因素之一。对1996年和1997年观测资料采用的箱型分析显示，河水径流明显地分散了开花，这意味着由于河水径流造成的水柱分层对于水华形成不是必要的。结论是，在风力和潮汐混合较少的情况下，平静的条件以及较少的河水径流被认为对于在日本广岛湾形成塔玛亚历山大河流水体是重要的。
