[{"name":"stordalen-mire-ch4-surface-concentration-1","title":"Methane concentrations from surface water on the Stordalen Mire, Abisko, Northern Sweden","summary":"This dataset provides surface concentration measurements of dissolved methane (CH\u2084), a strong climate forcing trace gas, in the surface water of three lakes surrounding the Stordalen Mire in northern Sweden.\r\n\r\nWater samples were collected during the ice-free seasons of 2007 to 2014, approximately every 1\u2060\u200a\u2013\u200a\u20603 weeks, from 8 different locations around the Mire, including weirs, lakes and streams. 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.","citations":"Wik M, Thornton BF, Bastviken D, Uhlb\u00e4ck J, Crill PM (2016) Biased sampling of methane release from northern lakes: a problem for extrapolation.
