Summary(Plain Language Summary, not published)
This Open File Report summarizes field activities undertaken jointly by Canadian and German researchers in the summer of 2018. The field work was conducted in the Mackenzie Delta area along the Inuvik - Tuktoyaktuk highway corridor and near the Hamlet of Tuktoyaktuk. The report presents preliminary results of scientific studies and provides a basis to appraise environmental change ongoing in the western Canadian Arctic. Chapters in the report review a methane release and other aspects related to environmental geoscience, as well as an appraisal of coastal, terrestrial and lacustrine permafrost processes.
