• Decadal-scale hotspot methane ebullition within lakes following abrupt permafrost thaw

  Open Access•Katey Walter Anthony, P Lindgren et al.•ARTICLE•Environmental Research Letters•2020

  Añadir item

  Thermokarst lakes accelerate deep permafrost thaw and the mobilization of previously frozen soil organic carbon. This leads to microbial decomposition and large releases of carbon dioxide (CO 2 ) and methane (CH 4 ) that enhance climate warming. However, the time scale of permafrost-carbon emissions following thaw is not well known but is important for understanding how abrupt permafrost thaw impacts climate feedback. We combined field measuremen…

• Contrasting lake ice responses to winter climate indicate future variability and trends on the Alaskan Arctic Coastal Plain

  Open Access•Christopher D Arp, Benjamin M Jones et al.•ARTICLE•Environmental Research Letters•2018

  Añadir item

  Strong winter warming has dominated recent patterns of climate change along the Arctic Coastal Plain (ACP) of northern Alaska. The full impact of arctic winters may be best manifest by freshwater ice growth and the extent to which abundant shallow ACP lakes freeze solid with bedfast ice by the end of winter. For example, winter conditions of 2016–17 produced record low extents of bedfast ice across the ACP. In addition to high air temperatures, t…
