The article analyses the experience of international scientific cooperation in the Arctic in organising and conducting an academic Swedish–Russian Arc-of-Meridian expedition to the Spitsbergen archipelago in 1898–1901. This was one of the largest projects of its kind in history. The military and naval government agencies of the two countries were extremely interested in measuring the meridian arc near the Geographic North Pole. The fulfilment of this task made it possible to more accurately determine the shape of the Earth as a geoid. This was the significant and fundamental result of testing the hypothesis of the Newton–Huygens spheroid and was of applied importance. Funding for the expeditionary activities was carried out on a parity basis from the budgets of the two nations. The study of archival documents from the collections of the Russian Academy of Sciences Archives enabled an understanding of the unprecedented financial and physical costs of preparing and carrying out expeditionary work. Analysing inter-academic research of the late nineteenth – early twentieth centuries is valuable for understanding the potential interactions between the government and academic structures of international scientific cooperation in the Arctic during the modern era.
