  1. 1. Temporal and spatial dynamics in subarctic peat plateaus and thermokarst lakes

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology (INK), Stockholm University

    Sammanfattning : Permafrost peatlands are widespread at high northern latitudes and are important soil organic carbon reservoirs. A future warming in these areas, as suggested by global climate models, can cause thawing and increased ground subsidence (thermokarst), resulting in changes in surface hydrology and ecosystem functioning.

  2. 2. Soil organic carbon in permafrost terrain Total storage, landscape distribution and environmental controls

    Sammanfattning : High latitude terrestrial ecosystems are considered key components in the global carbon (C) cycle and hold large reservoirs of soil organic carbon (SOC). To a large degree, this SOC is stored in permafrost soils and peatlands and is vulnerable to remobilization under future global warming and permafrost thawing. LÄS MER
