Since several decades, there’s a lot of discussion in the permafrost ecosystem community on “rewilding” and “return to a natural state” in order to protect ecosystems and to reduce the impacts of climate change. Reindeer and other herbivores influence the insulation regime of the ground and could thereby preserve the frozen state of permafrost ground. Is there a way to utilise this effect to our benefit, and make wild animals the “ecosystem engineers” of the Arctic? How are wild...| Cryospheric Sciences
Abstract. The organic-carbon (OC) pool accumulated in Arctic permafrost (perennially frozen ground) equals the carbon stored in the modern atmosphere. To give an idea of how Yedoma region permafrost could respond under future climatic warming, we conducted a study to quantify the organic-matter quality (here defined as the intrinsic potential to be further transformed, decomposed, and mineralized) of late Pleistocene (Yedoma) and Holocene (thermokarst) deposits on the Buor-Khaya Peninsula, no...| bg.copernicus.org
