摘要

摘要: 对中国第四次北极科学考察期间在白令海北部获取的海水样品进行悬浮体含量及其颗粒组分特征的分析。结果表明,白令海陆架海区悬浮体含量大体呈现出表层浓度低而底层浓度高的特点。表层海水悬浮体含量在白令海峡西侧和陆架东侧靠近阿拉斯加沿岸含量较高,而底层海水中悬浮体含量则在白令海峡西侧,以及白令海陆架西南部的圣马修岛西北侧较高。陆架流系对底床物质的再悬浮作用致使白令海悬浮颗粒物浓度的高值区多位于近底层海水中。受白令陆坡流沿陆架坡折带输运作用,研究区西南部悬浮体浓度较高。白令海陆架水以及阿纳德尔流携带悬浮颗粒向北输运,使得底层悬浮体浓度呈现出自南向北逐渐减弱的模式。圣劳仑斯岛以北靠近楚科奇半岛一侧海域,受高营养盐的阿纳德尔流的影响,悬浮颗粒物以藻类为主;东侧阿拉斯加沿岸流区悬浮颗粒则以陆源的碎屑矿物为主。

Abstract: The concentration and composition of suspended particulate matter (SPM) of the water samples,which were obtained in the northern of Bering Sea during the 4th Chinese Arctic Research Expedition,were measured to understand the distribution and origin of the SPM. The results showed that the concentration of the SPM was higher in the bottom water and lower in the surface. The surface highest SPM regions were in the west of the Bering Strait and the east of Bering Continental Shelf off the Alaska coast,while the bottom highest SPM regions were in the west of Bering Strait and the southwest of Bering Continental Shelf. The resuspension of bottom material by the shelf currents was the main reason of the higher concentration of the SPM in the bottom water. Bering Slope Current and Anadyr Current transported SPM northward,and Bering Slope Current also controlled the concentration of SPM along the shelf break zone. The concentration of SPM in bottom water decreased from south to north gradually. In the northwest of the St. Lawrence Island and off the Chukchi Peninsula,the SPM is mainly composed of diatoms,while in the east part of the Bering Sea where is also controlled by Alaskan Coastal Current the SPM is mainly composed of terrigenous clastic mineral.
