摘要: 对取自黄海中部的箱式沉积柱样进行颗石粒群落的分析,其结果为:颗石粒总丰度范围为7.0-55.1×10
6个/g,虽然不同种类的颗石粒在整个柱子中的丰度变化很大,但总的来说在群落中占有主要优势的有7个物种。其中,大洋桥石藻(Gephyrocapsa oceanica)占有绝对的优势,颗石粒平均相对丰度为50.1%,并且其相对丰度分布规律与贝氏布拉藻(Braarudosphaera bigelowii)和希布格脐球藻(Umbilicosphaera sibogae)(均为寡营养种)的颗石粒相对丰度的总和成相反趋势,这表明,在黄海大洋桥石藻分布情况可能与该海域可利用的营养盐有关。大洋桥石藻的颗石粒相对丰度与西伯利亚高压指数相似的分布规律表明,东亚冬季风可能是黄海生态变化的重要驱动因素。当东亚冬季风盛行时,黄海沿岸流和黄海暖流都加强,由此所带来的营养盐浓度增加和暖水有利于像大洋桥石藻这样的富营养暖水种的生长,这一机制也证明了气候变化可以通过海流等影响生态系统。 Abstract: A study of coccolith assemblages from a box core from the central South Yellow Sea (SYS) was performed revealing fluctuations on their relative abundance (%) that can be related to climatic and hydrographic changes over the last 230 years (1780-2011). Total coccolith abundances ranged from 7.0 to 55.1×106 coccoliths·g -1 sediment. Although the abundance of different species varied widely throughout the core, seven taxa dominated the assemblage. Among these species, Gephyrocapsa oceanica was the most dominant species, and it showed an average percentage of 50.1%. The pattern of G. oceanica (eutrophic species) was opposite to that of the combined percentage of Braarudosphaera bigelowii and Umbilicosphaera sibogae (both oligotrophic species), indicating that in the Yellow Sea (YS), the distribution pattern of G. oceanica might be characteristic of nutrient availability. Similar patterns between G. oceanica and the Siberian High were observed on an inter-decadal time scale, indicating that the East Asian Winter Monsoon (EAWM) may be an important driver of ecological changes in the YS. When the EAWM prevails, both the Yellow Sea Coastal Current (YSCC) and Yellow Sea Warm Current (YSWC) strengthen, and the increasing nutrient availability and warmer water brought by the strengthened YSWC favor eutrophic and warm-water coccolithophore species, such as G. oceanica. This likely mechanism demonstrates that coccolith assemblages can be used as benign and reliable proxy for climate change and surface oceanography. -
