1. Arctic Water System Change and its Interactions with Permafrost and Ecosystem Changes
Abstract : Climate change and various changes in the landscape itself, such as permafrost thaw, may trigger and mediate substantial changes in the inland water system of the Arctic. Many climate change responses in the Arctic landscape and ecosystems are then related to alterations in the hydrological system. READ MORE

2. High-resolution mapping and spatial variability of soil organic carbon storage in permafrost environments
Abstract : Large amounts of carbon are stored in soils of the northern circumpolar permafrost region. High-resolution mapping of this soil organic carbon (SOC) is important to better understand and predict local to global scale carbon dynamics. READ MORE

3. Land-atmosphere exchange of carbon in a high-Arctic wet tundra ecosystem
Abstract : Arctic ecosystems play a key role in the terrestrial carbon (C) cycle, but spa-tially explicit data on the C exchange is scarce in these remote areas. The global warming is especially dominant in the Arctic, and these areas are vul-nerable to climate change. READ MORE

4. The role of nutrients for stream ecosystem function in Arctic landscapes : drivers of productivity under environmental change
Abstract : Arctic and sub-Arctic freshwaters are currently experiencing substantial ecosystem changes due to the effects of global warming. Global warming effects on these freshwaters include increasing water temperatures, altered hydrological patterns, shifts in riparian vegetation and changes in the export of nutrients and carbon from soils.

5. Quantifying the impact of winter warming on the Arctic carbon cycle
Abstract : The Arctic has undergone extreme changes during the last decades and is warming over twice the global average. There has been increasing interest in understanding how warming and changes in snow and rainfall will affect high-latitude ecosystems. READ MORE
