During the first International Polar Year (1882–1883) the French expedition to Bahia Orange, Hoste Island, Tierra del Fuego carried out a series of 39 measurements of concentrations of carbon dioxide in the atmosphere. These were supplemented by 6 measurements during the return voyage to Cherbourg. In addition 20 similar measurements were made at 4 stations in the northern hemisphere and 17 at 3 stations in the southern hemisphere that were participating in the transit of Venus observations.
