Arctic Great Rivers Observatory IV Biogeochemistry and Discharge Data: 2020-2024

The PARTNERS (Pan-Arctic River Transport of Nutrients, Organic Matter, and Suspended Sediments) and Arctic-GRO (Arctic 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 IV (Arctic-GRO IV) Project spans the years between 2020 and 2024, 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.

PARTNERS（泛北极河流营养物质、有机质与悬浮沉积物输运项目，Pan-Arctic River Transport of Nutrients, Organic Matter, and Suspended Sediments）与Arctic-GRO（北极大型河流观测站项目，Arctic Great Rivers Observatory）针对注入北冰洋的六大河流开展生物地球化学采样：涵盖西伯利亚的叶尼塞河、鄂毕河、勒拿河与科雷马河，以及北美洲的育空河与马更些河。各河流的样品采集技术流程均保持最大限度的统一。采集完成后，所有样品将被运抵马萨诸塞州伍兹霍尔，随后分发至各专业实验室开展分析检测。北极大型河流观测站第四期（Arctic-GRO IV）项目实施周期为2020年至2024年，延续了自2004年起启动的长期样品采集工作。每条河流每两个月采样一次（每年6次），且各年度的目标采样月份交替轮换。如需获取北极GRO数据集的实时更新数据，请访问www.arcticgreatrivers.org/data。
