Abstract : Present gravity observations at sea are made on surface ships and on board submarines. These vessels present certain disadvantages because of the sea swell and because the coordinates of the submerged submarine cannot be determined with desired accuracy. A new method for gravity measurements at sea has been introduced. The device consists of a gondola which houses the measuring instruments and a dynamic sinker. With the aid of the sinker, the hermetical gondola, which has a certain buoyancy, decends to 100 meters, and in such a position is towed behind the ship. Gravity is measured with the aid of an automatic string gravimeter. Certain difficulties are caused by the movements of the gondola, though not so great as on a surface ship. A set of auxiliary instruments is installed in order to correct all disturbances. The new method for gravity measurement was tested in the Baltic and Black Seas. (Author)
