The International Arctic Science Committee (IASC, Fig. 1) commissioned an Action Group on Geosciences (AGG) in 2012. The principal aim of the AGG was to provide strategic advice to the IASC Council and Working Groups on the priorities and longer-term opportunities across a full range of Arctic geoscience. The AAG submitted its report in 2013. In addition to the report, the AGG undertook preparation of a set of papers to identify current controversies in the solid Earth sciences and to promote Arctic geoscience.
