Mapping ice in the Norwegian Arctic–on the edge between science and policy

Abstract

In the Norwegian Arctic, petroleum exploration is prohibited north of the ice edge (the zone between solid sea ice and open ocean); the mapping and definition of the ice edge becomes the boundary for petroleum exploration. However, no evidence-based scientifically ‘correct’ position of the ice edge exists. Defining the ice edge—and its geographic positioning—is the result of co-production processes involving multiple actors and practices. We explore how the use of a new dataset for determining the geographical position of the ice edge became the centre of a proxy debate over how far north petroleum exploration should be allowed. The analysis reveals how maps serve as visual discourses in debate, and a strong correlation between different definitions of the ice edge and political commitment to petroleum activities. We challenge and discuss the performativity of maps and how mismatches between expectations to knowledge-based management, including maps, may have democratic implications.
