Arctic Great Rivers Observatory III Biogeochemistry and Discharge Data, 2017-2019

The PARTNERS (Pan-Arctic River Transport of Nutrients, Organic Matter, and Suspended Sediments) and Arctic-GRO (Great Rivers Observatory) projects sample the biogeochemistry of the six largest rivers draining to the Arctic Ocean: the Yenisey, Ob', Lena, and Kolyma Rivers in Siberia and the Yukon and Mackenzie Rivers in North America. To the greatest extent possible, sample collection techniques are identical across rivers. Once collected, samples are returned to Woods Hole, Massachusetts, from where they are shipped to expert laboratories for analyses. The Arctic Great Rivers Observatory III (Arctic-GRO III; NSF-OPP-1602615 (National Science Foundation, Office of Polar Programs)) Project spans the years between 2017 and 2019, and continues a sample collection effort that has been ongoing since 2004. On each river, samples are collected bi-monthly (six times per year), with target sampling months alternating between years. Full field and laboratory details for Arctic GRO III can be found in the "Sample Collection and Analyses" document on this page.

PARTNERS（Pan-Arctic River Transport of Nutrients, Organic Matter, and Suspended Sediments，泛北极河流营养物质、有机质与悬浮泥沙输运）项目与Arctic-GRO（Great Rivers Observatory，北极大河流观测站）项目针对注入北冰洋的六大河流开展生物地球化学采样，涉及的河流包括西伯利亚地区的叶尼塞河、鄂毕河、勒拿河、科雷马河，以及北美的育空河与马更些河。所有采样河流均尽可能采用统一的样品采集技术。样品采集完成后，将被运送至马萨诸塞州伍兹霍尔，再从该处转运至专业实验室开展分析测试。北极大河流观测站第三期（Arctic Great Rivers Observatory III，简称Arctic-GRO III；资助编号NSF-OPP-1602615，美国国家科学基金会极地项目办公室）项目实施周期为2017至2019年，延续了自2004年起持续推进的样品采集工作。每条河流每两个月采样一次（全年共计6次），各年度的目标采样月份交替设置。Arctic GRO III的完整野外作业与实验室分析细节，可参见本页面的《样品采集与分析（Sample Collection and Analyses）》文档。如需获取Arctic GRO数据集的实时更新，请访问www.arcticgreatrivers.org/data。
