Triplicate water samples were collected from surface water (10\u2060\u200a\u2013\u200a\u206030 cm depth), and gas concentrations were measured using a gas chromatograph and a headspace extraction method.\r\n\r\nThe measurements could be used to assess the environmental drivers of CH\u2084 emissions  to the atmosphere from open waters around thawing permafrost peatlands, and relationships between carbon trace gas dynamics, biology, chemistry and local hydrology.","url":"http:\/\/bolin.su.se\/data\/stordalen-mire-ch4-surface-concentration-1","keywords":["Lacustrine","Arctic carbon","Lacustrine","Surface water","Lake","Pond","Methane","Subarctic","Earth science > Atmosphere > Atmospheric chemistry > Carbon and hydrocarbon compounds > Methane"],"creator":{"@type":"Person","name":"Patrick Crill, Martin Wik, Joachim Jansen"},"citation":"Wik M, Thornton BF, Bastviken D, Uhlb\u00e4ck J, Crill PM (2016) Biased sampling of methane release from northern lakes: a problem for extrapolation.
