我们观察到了一个不寻常的，亚热带吹的球形棕囊藻Scherlaughs在一个强大的上升流事件，并确认其身份使用形态，生理和遗传性状。2003年夏天，在南大西洋湾大陆架上发生了低纬度的P globosa种群水华。在这次地下水华期间测得的最大叶绿素a浓度为11.37 μ g L（-1），深度为31。潜水员报告在睡眠温跃层下有丰富的絮状物质，并使用显微镜将这种物质鉴定为棕囊藻。使用形态和生理特征以及18 S小亚基核糖体RNA基因（GenBank登录号EF 100712）的序列，这种浮游植物被鉴定为球形棕囊藻。物理和生物条件的相互作用可能会限制低纬度的P. globosa水华强烈的上升流事件。
We observed an unusual, subtropical blown of Phaeocystis globosa Scherffel during a strong up-welling event and confirmed its identity using morphological, physiological and genetic traits. This low-latitude bloom of P globosa colonies occurred on the South Atlantic Bight, continental shelf during the summer of 2003. Maximum chlorophyll a concentration measured during this subsurface bloom was 11.37 mu g L(-1) at 31 in depth. Divers reported abundant flocculent material below the sleep thermocline, and this material was identified as Phaeocystis sp. using microscopy Using morphological and physiological traits as well as the sequence of the 18S small subunit ribosomal RNA gene (GenBank Accession # EF100712), this phytoplankton was identified as P. globosa. Interactions of physical and biological conditions may restrict low-latitude P. globosa blooms to strong up-welling events.
