1白令海与西北冰洋表层沉积物粒度分布特征及其环境意义显示文摘基于中国第2次至第5次北极科学考察以及俄罗斯科学院远东分院太平洋海洋研究所提供的表层沉积物样品,开展粒度分析,研究表层沉积物粒度特征及其变化规律对沉积环境的指示意义。白令海与北冰洋表层沉积物类型比较丰富,沉积物主要来源于陆源碎屑,搬运方式以河流、海岸侵蚀、冰筏为主,辅以洋流。沉积物类型主要因为沉积物搬运方式及距离的远近产生差异,白令海北部及楚科奇海南部表层沉积物粒度随着离陆地距离的增大而逐渐减小,高纬地区的沉积物因冰筏沉积作用而分选较差。王春娟 刘焱光 董林森 刘大海 王国槐 李传顺 闫仕娟 Anatolii Astakhov 王汝建 2015海洋地质与第四纪地质2015,35,3:10

3Sources of particulate organic matter in the Chukchi and Siberian shelves: clues from carbon and nitrogen isotopes显示文摘The stable isotopic composition(δ13C andδ15N)and carbon/nitrogen ratio(C/N)of particulate organic matter(POM)in the Chukchi and East Siberian shelves from July to September,2016 were measured to evaluate the spatial variability and origin of POM.Theδ13CPOC values were in the range of−29.5‰to−17.5‰with an average of−25.9‰±2.0‰,and theδ15NPN values ranged from 3.9‰to 13.1‰with an average of 8.0‰±1.6‰.The C/N ratios in the East Siberian shelf were generally higher than those in the Chukchi shelf,while theδ13C andδ15N values were just the opposite.Abnormally low C/N ratios(<4),lowδ13CPOC(almost−28‰)and highδ15NPN(>10‰)values were observed in the Wrangel Island polynya,which was attributed to the early bloom of small phytoplankton.The contributions of terrestrial POM,bloom-produced POM and non-bloom marine POM were estimated using a three end-member mixing model.The spatial distribution of terrestrial POM showed a high fraction in the East Siberian shelf and decreased eastward,indicating the influence of Russian rivers.The distribution of non-bloom marine POM showed a high fraction in the Chukchi shelf with the highest fraction occurring in the Bering Strait and decreased westward,suggesting the stimulation of biological production by the Pacific inflow in the Chukchi shelf.The fractions of bloom-produced POM were highest in the winter polynya and gradually decreased toward the periphery.A negative relationship between the bloom-produced POM and the sea ice meltwater inventory was observed,indicating that the net sea ice loss promotes early bloom in the polynya.Given the high fraction of bloom-produced POM,the early bloom of phytoplankton in the polynyas may play an important role on marine production and POM export in the Arctic shelves.Renming Jia Xinyue Mu Min Chen Jing Zhu Bo Wang Xiaopeng Li A S Astakhov Minfang Zheng Yusheng Qiu 2020Acta Oceanologica Sinica2020,39,9:2
4北极东西伯利亚陆架黑碳的地球化学特征及其环境意义显示文摘热成因黑碳与气候变化和人类活动关系密切。在全球变暖背景下,这类碳的排放、从陆向海的转移及其环境归宿对于理解北极快速变化下陆源有机碳的源汇过程及其气候环境效应具有重要的科学意义。北极东西伯利亚陆架是全球最为宽浅的陆架,接收了大量来自径流和海岸侵蚀输入的陆源物质,尤其近年来环北极野火的频繁发生,因而成为研究北极沉积黑碳源-汇过程的理想区域。本研究对东西伯利亚陆架表层沉积物中黑碳的含量和组成、空间分布特征及其影响因素等进行了研究,结果表明,黑碳的含量为0.1~2.3 mg/g,平均为0.99 mg/g,其中来自生物质燃烧贡献为主的焦炭平均占70%以上。黑碳总体空间分布具有显著的异质性,拉普捷夫海和东西伯利亚海西部地区黑碳含量较高,与海岸侵蚀和河流输入关系密切;陆架东部(包括楚科奇海)陆源输入相对较少,黑碳含量相对较低。不同类型黑碳的空间分布格局显著不同;对于近岸区,来自径流和海岸侵蚀的输入可能是焦炭从陆向海的主要输入方式。于文秀 胡利民 石学法 张钰莹 叶君 白亚之 夏逸 杨刚 Anatolii Astakhov 2022海洋地质与第四纪地质2022,42,4:1
