Julian Murton from the University of Sussex presented contributions to a study soon to be published in Nature journal. In his presentation he discussed yedoma at Duvanny Yar, NE Siberia: a rich source of carbon and palaeo data from Pleistocene permafrost. These results provide new data on the development and persistence of permafrost soils in Arctic regions, and further insight into mega retrogressive thaw slumps, which are currently among the most important carbon emitters along the Arctic coastline.
