摘要:Abstract(#br)To explore the possibility of using ground ice archives for studies of the cosmogenic radionuclide 10 Be, we analyzed the beryllium isotopes in ice wedges exposed in the Cold Regions Research and Engineering Laboratory (CRREL) Permafrost Tunnel and the Barrow Pe...

摘要:Abstract(#br)For atmospheric gases and aerosols, snow and ice provide a useful archive of paleoenvironmental history. In the northern hemisphere, this archive has been largely limited to Greenland ice, but promising pioneering work has been done recently using chronology of ...

摘要:Thermokarst is the process of ground subsidence caused by either the thawing of ice-rich permafrost or the melting of massive ground ice. The consequences of permafrost degradation associated with thermokarst for surface ecology, landscape evolution, and hydrological processes ha...

摘要:Abstract(#br)Understanding permafrost soils’ response to global warming is critical for understanding changing global ecosystems. In the present study, we developed a dynamic system for measuring gas emissions from permafrost soils at different soil temperatures and checked ...

摘要:Abstract(#br)Understanding geocryological characteristics of frozen sediment, such as cryostratigraphy, ice content, and stable isotope ratio of ground ice, is essential to predicting consequences of projected permafrost thaw in response to global warming. These characterist...

摘要:Abstract(#br)A future increase in heavy precipitation events is predicted in boreal regions. An irrigation experiment was conducted in Taiga forest in eastern Siberia to evaluate the effect of heavy precipitation on greenhouse gas ([GHG] CO2, CH4, and N...

摘要:Eroding permafrost coasts are likely indicators and integrators of changes in the Arctic System as they are susceptible to the combined effects of declining sea ice extent, increases in open water duration, more frequent and impactful storms, sea-level rise, and warming perm...

摘要:The response of CH4 emission from natural wetlands due tometeorological conditions is important because of its strong greenhouseeffect. To understand the relationship between CH4 flux andwetting, we observed interannual variations in chamber CH4...

摘要:Abstract(#br)Permafrost landscape dynamics were investigated between 1998 and 2012 at Neleger, near Yakutsk, in central Yakutia, to determine the effects on permafrost of clear cutting of larch forest. Changes in ground temperature, soil moisture, seasonal thaw depth and sur...
