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, MA, from where they are shipped to expert laboratories for analyses. The Arctic Great Rivers Observatory III (Arctic-GRO III; NSF-OPP-1602615) 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.
