The Lena Delta is the largest delta in the Siberian arctic. It is a region of permafrost and patterned ground, with Crysols (accompanied by Histosols and Gleysols) as the dominant soil type. The region is highly sensitive to global change, particularly in terms of the genesis of methane, which is anticipated to have a significant positive feedback on global warming (Wagner et al., 2005).
