Abstract

Vast regions of Arctic Siberia, Alaska, and the Yukon Territory are covered by ice-rich silts penetrated by large ice wedges, resulting from syngenetic sedimentation and freezing. Because of fast incorporation of organic material into permafrost during sedimentation, Yedoma deposits include low-degraded organic matter. Moreover, ice-rich permafrost deposits like Yedoma are especially prone to degradation triggered by climate changes or human activity. When Yedoma deposits degrade, large amounts of sequestered carbon as well as other nutrients are released, which is of global significancefor the climate system.
