Constraining bubbling of methane from thermokarst lakes [PDF]
Eos, Transactions American Geophysical Union, 2013 In northern thermokarst lakes, which form in depressions left as permafrost thaws, methane, a greenhouse gas, can be released from lake sediments to the atmosphere through bubbling, or ebullition. Constraining the amount of methane released through bubbling would help scientists understand the role of thawing permafrost in the carbon cycle and global ...

Thermokarst lake waters across the permafrost zones of western Siberia [PDF]
, 2014 This work describes the hydrochemical composition of thermokarst lake and pond ecosystems, which are observed in various sizes with different degrees of permafrost influence and are located in the northern part of western Siberia within the continuous ...

Proximate Climate Drivers of Beaver Pond Occupancy and Range Expansion in Arctic Alaska
Global Change Biology Communications, Volume 1, Issue 3, September 2026.To understand why beavers are colonizing the Arctic, we evaluated which climate drivers underpin beaver pond dynamics. Warm Junes, mild winters, green summers, and wet springs facilitate pond establishment. Rapid improvement in these conditions across recent decades provides mechanistic support that climate change is driving beaver colonization of the ...

Thermokarst lakes increased atmospheric methane levels [PDF]
Eos, Transactions American Geophysical Union, 2012 Ice cores taken from Greenland indicate that during the last deglaciation, approximately 10,000 years ago, increases in temperature occurred at the same times as increases in atmospheric methane, a potent greenhouse gas. The source of the increase in atmospheric methane is still debated, but it has been suggested that thermokarst lakes, which form from

Limnology and Oceanography, Volume 71, Issue 7, July 2026.Abstract Despite the importance of coastal areas for the transfer of selenium (Se) from rivers to the open ocean and its bioavailability to food webs, dissolved Se concentrations and speciation in these ecosystems remain poorly understood. We conducted a 3‐yr study with monthly water column sampling at five stations spanning from the North Sea to the ...

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 473-497, July/September 2026.ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.
