Joint Russisa - US Cruise in the East-Siberian Sea

2003年夏天俄美联合巡航东西伯利亚海的意外许可，将使来自阿拉斯加大学和南卡罗莱纳大学的五名美国研究人员能够进行研究，将东西伯利亚流域与大陆架海的河流水域的命运和泛北极运输联系起来。游轮将用一套现代仪器在海岸和冰缘之间的横断面上取样水、颗粒物和沉积物。一组水化学测量（营养物，pH值，溶解氧，溶解甲烷）将在采样后立即或直接在原位进行（二氧化碳分压，CDOM, Chl）。在巡航结束后，将使用阿拉斯加大学、南卡罗来纳州大学和俄罗斯科学院远东分院的设备对水和沉积物进行额外的测量（DOC、O-18、C-13、N-15、生物标志物、化学成分）。东西伯利亚的一个样带将为世界海洋中最宽、最浅和未开发的区域提供新的测量，该区域代表了当地大陆架水域和太平洋派生水域之间的边界。新的CTD和生物地球化学数据将大大有助于了解水文和水化学参数如何响应大气条件的短期变化，并更好地了解北极欧亚大陆架上的大气强迫、河流流量和海洋过程之间的联系，特别关注太平洋来源的水域向西渗透。新的数据还将有助于建立一个可信的当前区域夏季二氧化碳预算，这对于可靠地预测与海冰、大气和水循环变化有关的大气二氧化碳变化至关重要。拟议的工作还将通过支持研究生（两名来自美国，两名来自俄罗斯）来促进教学和培训，并将提供一个向公众，特别是本科生开放的网站。它将为美国工人提供一个机会，在亚洲北极地区就泛北极陆架和陆架-盆地相互作用开展共同项目，从而加强合作。这是本地区第一次真正的合作企业，有理由相信俄罗斯同事希望进行真正的合作。在俄罗斯专属经济区工作的新经验（包括物流和海关问题）将有助于计划进一步的美国研究，并与FEBRAS在北冰洋太平洋地区（主要是俄罗斯专属经济区）建立长期的相互合作关系。

A surprise permission for a joint Russia-US cruise to the East-Siberian Sea in the summer of 2003 will enable five US researchers from the University of Alaska and University of S. Carolina to conduct research linking the fate of riverine waters from East-Siberian watersheds to the shelf seas and pan-arctic transport. The cruise will sample water, particulate matter, and sediments with a set of modern instruments on transects between the coast out to the ice edge. A set of hydrochemical measurements (nutrients, pH, dissolved oxygen, dissolved methane) will be done immediately after sampling or directly in situ (pCO2, CDOM, Chl). Additional measurements (DOC, O-18, C-13, N-15, biomarkers, chemical composition) in water and sediment will be done after the cruise using facilities of the University of Alaska, University of S. Carolina, and the Far Eastern Branch of the Russian Academy of Sciences (FEBRAS).A transect of the East Siberian will provide new measurements across the widest and most shallow and unexplored area in the World Ocean that represents a boundary zoe between local shelf waters and Pacific derived waters. New CTD and biogeochemical data will contribute significantly towards understanding how the hydrological and hydrochemical parameters respond to short-term changes in atmospheric condition and to understand better connections between atmospheric forcing, river discharge and oceanological processes over the Arctic Eurasian shelf, with a special eye onto the westward penetration of the Pacific-derived waters. New data will help also to construct a believable present-day regional summertime CO2 budget that is essential for reliable prediction of changes in atmospheric CO2 in connection with the sea ice, atmosphere and water circulation changes.Broader Impacts and Intellectual MeritThe proposed work will also promote teaching and training through support for graduate students (two from US, and two from Russia), and will provide a web site accessible to the public, especially for undergraduate students. It will enhance collaboration by providing an opportunity for USA based workers to collaborate on a common project in the Asian Arctic on Pan-Arctic land-shelf and shelf-basin interactions. This is a first real cooperative venture in this region and there is reason to believe that Russian colleagues desire genuine cooperation. New experience to work in the Russian EEZ (including logistics and custom issues) will help to plan further US studies and establish a long-term mutual cooperation in the Pacific sector of the Arctic ocean (mostly Russian EEZ) with FEBRAS.
