 The ability to photograph, and observe the Arctic from an aircraft, provided researchers with a larger scope that allowed them to see a massive amount of space at one time, while also asserting objectivity.A photograph produces evidence, similar to laboratory data, yet it can be understood, circulated and accepted by the common people due to its aesthetic value.During the Cold War, the Canadian government began taking initiatives to secure the continent, and to assert territorial authority over northern Canada, including the Arctic, which at the time had a dominant American presence.
