The Arctic Great Rivers Observatory (Arctic-GRO)

大量的北方河流将大量的淡水、碳和其他化合物从大陆输送到北冰洋。 北极大河观测站（Arctic-GRO）的总体科学原理是，大河水文学和化学可用于评估通量的变化，这些变化标志着大陆上的区域和泛北极变化，并随后影响沿海和海洋化学，生物学和循环。 六条北极-GRO河流的流域是地球上最大的流域之一，总面积为11，400，000平方公里，超过一半的面积流入北冰洋。 鉴于河流的地球化学整合过程发生在整个流域，北极GRO？对鄂毕河下游的系统采样，西伯利亚的叶尼塞河、勒拿河和科雷马河以及北美的育空地区河和麦肯齐河为评估北极的环境变化提供了极好的手段。 将开展各种活动，以确保北极-全球区域办事处产生广泛的影响。 这些活动将包括：（1）维护和加强一个项目网站www.arcticgreatrivers.org;（2）制作和广泛分发两个关于北极-全球区域办事处和北极观测网络的多媒体录像带;（3）与育空地区河流域部落间理事会理事会合作，在育空地区和勒拿河流域的土著人民之间进行交流;（4）扩大一个巡回艺术展，讲述气候变化的故事及其对北极的影响，展出西伯利亚和北美北极地区土著儿童的艺术作品。

Arctic-GRO Non-Technical AbstractMassive northern rivers transport huge quantities of freshwater, carbon, and other compounds from the continents to the Arctic Ocean. The overarching scientific rationale for the Arctic Great Rivers Observatory (Arctic-GRO) is that large river hydrology and chemistry can be used to assess changes in fluxes that signal regional and pan-arctic change on the continents and that subsequently impact coastal and ocean chemistry, biology, and circulation. The watersheds of the six Arctic-GRO rivers are among the largest on Earth and combined cover 11,400,000 km2, more than half of the area that drains into the Arctic Ocean. Given that the biogeochemistry of rivers integrates processes occurring throughout their watersheds, Arctic-GRO?s systematic sampling of the downstream reaches of the Ob?, Yenisey, Lena, and Kolyma rivers in Siberia, and the Yukon and Mackenzie rivers in North America, provides a superb means for assessing environmental change in the Arctic. A variety of activities will be pursued to ensure that Arctic-GRO has substantial broader impacts. These activities will include 1) the maintenance and enhancement of a project website, www.arcticgreatrivers.org, 2) the production and widespread distribution of two multimedia videos about Arctic-GRO and the Arctic Observing Network, 3) an exchange between indigenous people in the Yukon and Lena river watersheds, in partnership with the Yukon River Inter-tribal Watershed Council, and 4) the expansion of a traveling art exhibition that tells the story of climate change and its impact in the Arctic, featuring artwork done by indigenous children from the Siberian and North American Arctic.
