| 摘 要： | 2007年秋季(10月)在黄海22个站位采集表层沉积物样品进行甲藻孢囊的种类鉴定与计数,本航次中共鉴定出33种(不包括2个未确定种),优势种是锥状斯克里普藻(Scrippsiella trochoidea)、塔玛亚历山大藻(Alex-andrium tamarense)和膝沟藻属(Gonyaulaxsp.)的种类。与东海和南海甲藻孢囊的同期丰度相比,黄海的相对较低,丰度范围为10~519个/cm3,平均108个/cm3。孢囊丰度总体分布趋势从北向南递增,最高丰度区出现在长江口以北(32°19′59.88″N,122°37′5.16″E),另外,在南黄海调查海域中,中部黄海冷水团区域孢囊丰度较高,膝沟藻成为该区域的优势种,密集中心达101个/cm3。有毒甲藻孢囊在沉积物表层聚集且分布广泛,有爆发赤潮的可能。

| Abstract: | Dinoflagellate cysts in the surface sediment were sampled at 22 stations in the Yellow Sea in October 2007.33 cyst species are identified and counted,excluding 2 uncertain species.The dominant species are Scrippsiella trochoidea,Alexandrium tamarense,Gonyaulax sp.The dinoflagellate cyst abundance is less in the Yellow Sea than in the East China Sea or in the south China Sea in the same time.The abundane ranges from 10 cysts/cm3 to 519 cysts/cm3,and the average is 108 cysts/cm3.The abundance tends to be incr... |
