Observing Seasonal Cycles in Greenhouse Gas Fluxes with Automatic Flushing Chambers in a Low-Arctic Lake
The Arctic is warming nearly four times faster than the global average. Greenhouse gases (GHG) are causing a changing climate which is affecting permafrost thaw, sea ice melt, and changing hydrological dynamics. Lakes in the Arctic and sub-Arctic regions are increasingly recognised as important …

Investigating dissolved organic matter cycling in High Arctic ponds and soils
… lability has been investigated extensively in Arctic lake and large river systems, however relatively little research has investigated the lability of DOM in systems with more fine scale spatial heterogeneity in environmental conditions, such as ponds and soils. Chapter 2 presents a study of …

The seasonal dynamics of Arctic surface hydrology in permafrost environments
… and hydrologi- cal cycling. In the Arctic and sub-Arctic permafrost zones, rising air temperatures are warming, and in some regions even thawing, the frozen ground. Permafrost is a carbon sink. The thermal state of the ground therefore has important implications on carbon exchange …

Microbial communities and their response to Pleistocene and Holocene climate variabilities in the Russian Arctic
The Arctic is considered as a focal region in the ongoing climate change debate. The currently observed and predicted climate warming is particularly pronounced in the high northern latitudes. Rising temperatures in the Arctic cause progressive deepening and duration of permafrost thawing during …
