Variations of Siliceous Microorganisms in Surface Sediments of the Bering Sea and Their Environmental Control Factors
-
摘要: 中国首次北极科学考察在白令海采取了12个表层沉积物样品, 其中对硅质生物和陆源碎屑的详细研究发现, 它们主要由硅藻、放射虫和海绵骨针组成.其中, 硅藻在样品中的丰度均占绝对优势, 高出放射虫和海绵骨针一个数量级.它们与环境控制因素关系的分析表明, 硅藻、放射虫和海绵骨针丰度的高低及其保存程度与深度、温度、盐度和受大规模季节性气候变化控制的表层海水的高营养和高生产力, 以及陆源物质输入的变化密切相关.这一研究结果对白令海第四纪的古气候与古海洋学研究具有十分重要的意义.Abstract: Based on the quantitative studies of siliceous microorganisms and terrestrial detritus in 12 surface sediment samples, which were recovered by the First Chinese National Arctic Expedition team, in the Bering Sea, it goes without saying that diatom abundance is dominant within the microorganisms which consists of diatoms, radiolarians and sponge spicules. The relationship between the microorganisms and environmental control factors, for example, water depth, temperature and salinity are analyzed and discussed. It is evident that their abundance change and preservation are associated closely with these environmental control factors, and high surface nutrient and productivity controlled by the variations of large scale seasonal climate and input of terrestrial detritus. This investigation is very significant for the further studies on paleoclimate and paleoceanography in the Bering Sea.
