We thank help from Danish-Korean expedition team during the field
seasons. The research has been conducted under permissions from the
Greenland government and these permits include consideration and
approval of fecal sampling for muskoxen (permission no. G16-074,
C-17-4). The local ethics committee (Ministry of Industry and Mineral
Resources, the Government of Greenland) specifically reviewed and
approved the application for survey license on the use of biological
resources for commercial and research purposes (in the following: Act on
Biological Resources).
