DOI: 10.1002/2016jg003688
Abstract: Vast stores of arctic permafrost carbon that have remained frozen for millennia are thawing, releasing ancient dissolved organic carbon (DOC) to arctic inland waters. Once in arctic waters, DOC can be converted to CO2 and… read more here.

The development of permafrost bacterial communities under submarine conditions
Sign Up to like & getrecommendations! Published in 2017 at "Journal of Geophysical Research"
DOI: 10.1002/2017jg003859
Abstract: Submarine permafrost is more vulnerable to thawing than permafrost on land. Besides increased heat transfer from the ocean water, the penetration of salt lowers the freezing temperature and accelerates permafrost degradation. Microbial communities in thawing… read more here.

DOI: 10.1002/ece3.9106
Abstract: Abstract Soil microorganisms are crucial contributors to the function of permafrost ecosystems, as well as the regulation of biogeochemical cycles. However, little is known about the distribution patterns and drivers of high‐latitude permafrost microbial communities… read more here.

DOI: 10.1002/esp.4698
Abstract: An overall acceleration of rock glacier displacement rates in the Alps has been observed in recent decades, with several cases of destabilization leading to potential geomorphological hazards. This behaviour has been attributed to the rising… read more here.

DOI: 10.1002/ppp.1897
Abstract: 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… read more here.

Radium isotope fingerprinting of permafrost ‐ applications to thawing and intra‐permafrost processes
Sign Up to like & getrecommendations! Published in 2019 at "Permafrost and Periglacial Processes"
DOI: 10.1002/ppp.1999
Abstract: Permafrost in circum‐polar regions has been recently undergoing thawing, with severe environmental consequences, including the release of greenhouse gases and amplification of global warming. Although highly important, direct methods of tracking thawing hardly exist. In… read more here.
