Just like changes in blood chemistry can be used to diagnose an individual?s health, so too can changes in river water chemistry be used to evaluate the condition of a river?s watershed. In the Arctic, six massive rivers capture freshwater runoff from two-thirds of the land area that drains to the Arctic Ocean. The chemistry of this runoff reflects watershed characteristics (e.g. soil composition), and carries essential nutrients to the marine environment. The overarching scientific objective of the Arctic Great Rivers Observatory (Arctic-GRO) is to make sustained observations of the chemistry of these six large rivers, which is vital for assessing changes on land that subsequently impact physical, chemical, and biological properties of the Arctic Ocean. The project involves partnerships with the Yukon River Intertribal Watershed Council, The Pilot Station Traditional Council, the Gwichya Gwich?in Renewable Resource Council, and with the University of Alaska at Kuskowkwin community college that serves the largely Yup?ik residents of the Yukon-Kuskowkwim Delta. . The six rivers included in the Arctic Great Rivers Observatory are the Yukon and Mackenzie in North American and the Ob?, Yenisey, Lena, and Kolyma in Eurasia. The rivers will be sampled near their mouths, every two months for three years, using identical sample collection and preservation protocols. Approximately 40 parameters will be measured on all samples including dissolved and particulate organic carbon concentrations and isotopic compositions, concentrations of dissolved nutrients, major ions, and trace elements, and optical properties of dissolved organic matter, including UV absorbance and fluorescence excitation-emission matrices. For QA/QC purposes, every analysis will be conducted at a single laboratory. The resulting data, along with complementary data on river discharge, will be made available without restriction at the Arctic-GRO website (arcticgreatrivers.org) and through the NSF Arctic Data Center. Arctic-GRO data, which build on observatory records that extend back to 2003, provide valuable end-members for the oceanographic research community as well as for analyses of terrestrial landscape change.

就像可以使用血液化学的变化来诊断个人的健康一样，也可以使用河水化学的变化来评估河水的状况。 在北极，六条巨大的河流捕获了从北极海的三分之二的陆地区域中捕获的淡水径流。 这种径流的化学反映了流域特征（例如土壤组成），并将必需的养分带到海洋环境。 北极大河天文台（Arctic-GRO）的总体科学目标是对这六个大河的化学反应进行持续的观察，这对于评估随后影响北极海洋物理，化学和生物学特性的土地变化至关重要。该项目涉及与Yukon河间分水岭委员会，飞行员站的传统委员会，Gwichya Gwich？在可再生资源理事会中的Gwichya Gwich以及阿拉斯加大学Kuskowkwin社区学院的合作伙伴关系，该学院为Yukon-Kuskowkwim delta的Yukon-Kuskowkwim delta提供了很大的服务。 。北极大河天文台中包含的六条河流是北美的育空地区和麦肯齐，以及欧亚大陆的Yenisey，Lena和Kolyma。 河流将使用相同的样品收集和保存方案，每两个月在嘴附近进行一次采样，每两个月，持续三年。 将在所有样品上测量大约40个参数，包括溶解和颗粒有机碳浓度和同位素组成，溶解营养素的浓度，主要离子和微量元素，以及溶解有机物的光学特性，包括紫外线吸收和液化性兴奋 - 兴奋 - 兴奋 - 发射 - 发射发射 - 发射 - 发射 - 发射发射矩阵。 出于QA/QC的目的，每个分析都将在一个实验室进行。 最终的数据以及有关河流排放的补充数据将在北极GRO网站（arcticgreatrivers.org）和NSF北极数据中心提供而无需限制。 基于天文台记录的北极-GRO数据可追溯到2003年，为海洋研究界提供了宝贵的终点，以及陆地景观变化的分析。
