对大洋钻探686B孔第四纪沉积物中的甲藻孢囊组合进行了测定。结果被解释为显示，在强大的上升流条件下，组合丰富的多甲纲包囊，相反，弱上升流的情况下，gonyaulacean包囊成为主导。结果进行了讨论，目前的南极组合和生活方式。这可能扩展了甲藻作为该地区古生态指示的用途。
The dinoflagellate cyst assemblages from Quaternary sediments of Ocean Drilling Program (ODP) Hole 686B were determined. Results were interpreted as showing that under strong upwelling conditions assemblages are enriched with peridiniacean cysts, in contrast to weak upwelling situations where gonyaulacacean cysts become dominant. Results are discussed in relation to current planktonic assemblages and lifestyles. This possibly extends the use of dinoflagellates as paleoecological indicators in this region.
