Dataset
Methane production in the Artic: Isotopic d13C methane measurements taken from Alaskan wetland, 2018 - 2019
Abstract
Isotopic sampling of methane from tedlar bag samples collected over Alaskan wetlands, samples analysed at Royal Holloway University of London
This dataset contains air sample measurements of isotopic d13C methane. The measurements were collected using regular flask samples over Alaskan wetlands. The samples were analysed Royal Holloway University of London using continuous flow gas chromatography/isotope ratio mass spectrometry (CF-GC/IRMS).
These data were collected as part of theMethane Production in the Arctic: Under-recognized Cold Season and Upland Tundra - Arctic Methane Sources (UAMS) project funded by the Natural Environment Research Council (NERC) (NE/P002552/1).
