|a Permafrost soils contain nearly twice as much carbon as
the atmosphere1. When these soils thaw, large quantities
of carbon are lost, mainly in the form of methane and
carbon dioxide1–9. In contrast, thawing is thought to have
little impact on nitrous oxide emissions, which remain minimal
following the summer thaw4. Here, we examined the impact
of thawing on nitrous oxide production in permafrost cores
collected from a heath site and a wetland site in Zackenberg,
Greenland. Rates of nitrous oxide production in the heath
soil were minimal, regardless of the hydrological conditions.
Although rates of nitrous oxide production in the wetland
soil were low following thawing[ ].
Measurements of nitrous
oxide production in permafrost samples from five additional
wetland sites in the high Arctic indicate that the rates of
nitrous oxide production observed in the Zackenberg soils may
be in the low range. |
