Eight years later, a new phase of the marine research began. As so far, the marine research continued but from now, different countries worked together on one expedition. The German "Altair" and the Norwegian "Armauer Hansen" performed a common measurement program within the scope of the international Gulf Stream expedition that shed light on the fluctuation of the Gulf Stream. For this international experiment the German "Meteor", the Danish "Dana," and the French air-base vessel "Carimare" delivered data. In the same year, unconventional ships began with marine research.
