Concentration of suspended particulate matter and magnetic minerals from surface seawater in Russian Arctic Seas: Distribution and influencing factors
-
摘要:
为了解俄罗斯极地海悬浮体颗粒物（Suspended Particulate Matter，SPM）的分布特征及其沉积学意义，对2019年中俄北极联合考察（AMK78航次）在喀拉海-拉普捷夫海-东西伯利亚海表层海水采集的SPM样品开展了颗粒浓度、组成和岩石磁学分析。研究发现，SPM主要由陆源碎屑和硅质浮游生物碎屑组成。悬浮体浓度在德米特里拉普捷夫海峡及其东侧海域最高，鄂毕河和叶尼塞河河口外侧次之，其他海域整体较低。悬浮体中携磁矿物为单畴、多畴磁铁矿。陆源碎屑集中分布在近岸和河流入海口附近海域,离海岸和河口较远海域悬浮体中硅质生物碎屑占比升高。SPM浓度主要受到河流搬运入海的陆源碎屑通量和海岸侵蚀的影响，而SPM中磁性矿物与流域内岩石类型有关，并受西伯利亚沿岸流的影响，磁性矿物集中在洋流流速缓慢的区域，粒径粗的磁性矿物分布在沿岸地区，可能与海岸侵蚀有关。
Abstract:To understand the distribution characteristics and sedimentological significance of suspended particulate matter (SPM) in the Russian Arctic Seas, the particle concentration, composition, and rock magnetism of SPM samples collected in the surface seawater of the Kara Sea-Laptev Sea-Eastern Siberia Sea during the Sino-Russian joint Arctic expedition (AMK78 voyage) were analyzed. Results show that the SPM was mainly composed of terrigenous detritus and siliceous plankton debris. The SPM concentration was the highest in the Dmitry Laptev Strait and its eastern sea areas, followed by the outer sides of the Ob and Yenisei estuaries, and were generally lower in the other sea areas. The magnetic minerals in the SPM were single-domain and multi-domain magnetite. The terrigenous detritus was concentrated in the waters near the coast and the estuary of the river, and the proportion of siliceous bioclasts in the SPM in the sea farther from the coast and the estuary increases. The SPM concentration was mainly affected by the flux of terrigenous debris transported into the sea by rivers and coastal erosion, while the magnetic minerals in SPM were related to the rock types in the watershed and were affected by the Siberian Coastal Current. Coarse magnetic minerals were distributed in the coastal areas, which might be related to coastal erosion.
