Objectif(s): To reconstruct history of hummocky soil formation.

Description du projet: “Drunken forest” is developed on earth hummocks on shallow permafrost layer near Inuvik, Canada. Black spruce forests are typically grown on the shoulder of mounds and tree rings record the history of soil movement. By reading tree rings, The Principal Investigator (PI) is planning to reconstruct history of hummocky soil formation. The PI will collect tree core samples by making a hole in wood of black spruce trees (20 trees). The PI will also survey permafrost-affected soil by digging soil pits (5 pits). The research is fundamental, but it can provide information of dynamics of permafrost and effects of climate change on permafrost soil. The PI will submit interim reports or papers to Aurora Research Institute. The fieldwork for this study will be conducted from September 1, 2019 to September 10, 2019.
