Voyage du S.Y. Belgica 1897-1899. Volume 5. Rapport sur les densités de l'eau de mer

During the cruise of the Belgica, from the island of Madeira to Rio de Janeiro, in Montevideo and the Magellan straight, determinations of surface water density have been carried out three times a day. Later, during the first soundings of the Belgica, conducted between State Island and the southern Shetlands, bottom water was sampled and studied. These studies, interrupted during the geographic discovery cruise in Antarctica, were resumed in the Pacific Ocean, beyond the Polar Circle, and, during the wintering of the Belgica in the South Pole ice fields, water was sampled at great depths and studied, on board, in the physics laboratory. This report details the numerical results obtained through these observations. The first two paragraphs deal with the operating techniques used on board and the corrections applied to the obtained figures during the experiences; then, in the next three paragraphs, readers will find information on the determined densities as well as charts gathering the obtained figures.
