the stops occurred without incident. On 25 October, Delphin arrived in Constantinople. The navy ministry had intended to use Delphin to carry the archaeologist Ernst Curtius back from Piraeus, but he left on another vessel on 12 October, while Delphin was still en route. In February 1872, she carried Prince Friedrich Karl on his tour of Greece and the Ottoman Empire, making stops in Athens, Greece, and Chios, Bursa, and Constantinople in the Ottoman Empire. Delphin cruised the Danube in October and November that year. In early March 1873, the navy sent Delphin to Spain to join the ironclad and the corvette to protect German interests during the Third Carlist War. The German vessels, commanded by now-Konteradmiral (Rear Admiral) von Werner, joined a British squadron. The Anglo-German force blockaded Cartagena, which was then controlled by the rebel faction, and attacked two rebel-controlled ironclads, forcing them to surrender. On 4 October, Delphin was replaced by her sister . Delphin returned to Kiel, where on 4 December, she was once again decommissioned. Work then began to convert her into a survey vessel; this included removal of her armament, construction of a deck house, replacement of her barquentine rig with a barque rig, and the installation of a new bridge. The work was finished by April 1874, and she thereafter began survey work with her similarly converted sister . Delphin was again decommissioned for the winter on 21 October. She returned to service each year through 1879 during the summer months, before being decommissioned each year in October or November. During this period, she surveyed the area around Heligoland in 1877 and covered some of the Baltic between 1878 and 1879. In 1880 she had her rigging removed, and though not officially commissioned, took part in the raising of the aviso in October and November, which had been sunk in torpedo tests with the aviso on 14 July. Delphin was recommissioned a last time on 15 March 1881 for service as a fishery protection ship, but this service was short-lived. Delphin was decommissioned on 13 August, stricken from the naval register on 30 September, and thereafter sold to ship breakers for scrap.
