Abstract:

This file presents the detailed description of two deep permafrost cores from the Yukechi Alas landscape in Central Yakutia, Russia. These data were recorded during subsampling of the cores and are based on visual and haptic impression. The core "YED1" is a Yedoma permafrost core. Core was obtained during field work in March 2015.
