Description
Summary:Here, we conducted in situ measurements of soil and pond VOC emissions across an actively degrading permafrost peatland in subarctic Norway. We used a permafrost thaw gradient that covered bare soil and vegetated palsa plateaus, underlain by intact permafrost, and increasingly degraded permafrost landscapes: thaw slumps, thaw ponds, and vegetated thaw ponds. This dataset includes two excel files: 1) the first one "Finnmark_source_data" is the source data for figures in the publication https://doi.org/10.1016/j.geoderma.2023.116355. ii) the second one "Rawdata_of_emission_rate" is the emission rate of the 210 VOC species identified in this study. Results showed that every peatland landscape type was an important and consistent source of atmospheric VOCs, with a large variety species, such as methanol, acetone, monoterpenes, sesquiterpenes, isoprene, hydrocarbons, oxygenated VOCs, etc. VOC composition varied considerably across the measurement period and across the permafrost thaw gradient. We observed ...
