Description

This dataset contains greenhouse gas flux measurements, namely:

  • methane (CH4),
  • carbon dioxide (CO2), and
  • nitrous oxide (N2O)

and auxiliary data, including PAR (Photosynthetically Active Radiation), soil moisture, and soil temperature from manual chamber campaigns at the Stordalen Mire (68.20°N, 19.03°E, 351 m above sea level) in sub-Arctic Sweden in September 2022, May, July, and September 2023, and June, July, and August 2024.

The Stordalen Mire is located within the sporadic permafrost zone, adjacent to Lake Torneträsk. A large portion of the mire consists of a slightly elevated drained area, interspersed with wetter depressions, which are not underlain by permafrost. It is located on the 0°C isotherm, which causes the permafrost in the mire to be sporadic and highly dynamic in nature. As a result of recent years of warming in the area, permafrost has been observed to degrade in many parts of the mire.

More information on Stordalen can be found here:

Our dataset is grouped into four different microhabitats along a thawing (moisture) gradient from dry to wet: palsa lichen (dry), palsa moss (dry), bog (wet), and fen (wet).
