The Swedish-Russian Arc-of-Meridian Expedition took place during five summer seasons and one winter season at Svalbard, from 1899. The purpose of the mission was to measure the meridian arcs, in order to calculate whether earth flattening was larger at the poles.
The measurements were done by an establishing a chain of triangulation points from Keilhaufjellet in Sørkapp Land to Vesle Tavleøya north of Nordaustlandet. The Russians were responsible for the southern measurements, while the Swedes performed the northern measurements from a base at Crozierpynten in the fjord of Sorgfjorden.
