Onatsevich, Mikhail Lyutsianovich (1847–1879) – Russian researcher of the Far Eastern seas and a naval lieutenant. In 1868, he graduated from the Naval Academy, was promoted to midshipmen, and was assigned to the circumnavigation on the clipper “Vsadnik.” Within 3 years, O. actively participated in the hydrographic survey in the Sea of Japan (recordings and measurements of the Hakodate Harbor and Aniwa Bay, chronometric connection of the South Sakhalin and the Japanese islands). From 1872 to 1874, he was a trainee of the hydrographic department of the academic course of Marine Sciences. He was appointed the head of OSVO. In 1875, he conducted a winter survey in the Gulf of Peter the Great and then on the schooner “Vostok” explored the northwest coast of the Sea of Okhotsk from Ayan to Gizhiginskaya Bay and drew up a map of Tauyskaya Bay. After wintering in Hakodate, Japan, he went into the Bering and Chukchi Seas, where he conducted extensive hydrographic surveys: measurements and preparation of plans and maps of the Bay of Krest and Providence Bay, Saint Lawrence Bay, Bay of Gavriil, and Olyutorsky Bay. At the same time, astronomical, magnetic, and hydrological measurements were carried out under his leadership. In 1878, the Marine Scientists Committee published his report, which was highly appreciated by specialists.
Major works: “Astronomical Observations in the Sea Made While Sailing on Clipper Vsadnik in 1868–1871” (1872), “A Brief Hydrographic Overview of the Voyage of the Schooner Vostok in 1875” (1876), and “A Collection of Observations Made During the Hydrographic Trip to the Eastern Ocean in 1874–1877” (1878).
The name of O. was given to a cape and a peninsula in Tauyskaya Bay in the Sea of Okhotsk. The Maritime Academy put his name on a marble plaque with the names of the most prominent marine researchers.
