Subsequently he became instructor of the grand duke Constantine Nikolavevitch, and rose to the rank of vice admiral in 1843. In 1845 he promoted the establishment of the geographical society, of which he was several times vice president. He was governor of Revel from 1850 to 1853, and afterward of Cronstadt, and became in 1855 a member of the council of state, with the full rank of admiral. In 1864 he succeeded Bludoff as president of the academy of sciences. His principal works are: " Four Journeys through the Northern Arctic in 1821-'4" (St. Petersburg, 1828; German translation by Erman, Berlin, 1835), and a narrative of his journey round the world, including his discovery of three new groups of islands, which, after the name of his ship, he called the Seniavin islands (3 vols., St. Petersburg, 1834-'6; French translation, 3 vols., Paris, I835-'6).
