Schmidt was a celebrated explorer of the Arctic. In 1929 and 1930, he led expeditions on the steam icebreaker Georgy Sedov, establishing the first scientific research station on the Franz Josef Land, exploring the northwestern parts of the Kara Sea and western coasts of Severnaya Zemlya, and discovering a few islands. In 1932, Schmidt's expedition on the steam icebreaker Sibiryakov with Captain Vladimir Voronin made a non-stop voyage from Arkhangelsk to the Pacific Ocean without wintering for the first time in history
