Methane concentrations from surface water on the Stordalen Mire, Abisko, Northern Sweden

Patrick Crill, Martin Wik, Joachim Jansen

This dataset provides surface concentration measurements of dissolved methane (CH₄), a strong climate forcing trace gas, in the surface water of three lakes surrounding the Stordalen Mire in northern Sweden.

Water samples were collected during the ice-free seasons of 2007 to 2014, approximately every 1⁠ – ⁠3 weeks, from 8 different locations around the Mire, including weirs, lakes and streams. Triplicate water samples were collected from surface water (10⁠ – ⁠30 cm depth), and gas concentrations were measured using a gas chromatograph and a headspace extraction method.

The measurements could be used to assess the environmental drivers of CH₄ emissions to the atmosphere from open waters around thawing permafrost peatlands, and relationships between carbon trace gas dynamics, biology, chemistry and local hydrology.

Data description

This dataset consists of one comma-separated values (.csv) file (data), one .rtf file (readme with measurement and site info) and one .pdf file (map with sampling locations and illustration of sampling system). The csv file has Western Europe (ISO-8859-15/EURO) encoding.

The data file has four data columns:

• Sampling location (site number)
• Sampling time
• Concentration (µmol CH₄ / L)
• Standard deviation of the concentration of 3 replicate samples
