On the way from Japan to Kamchatka, Krusenstern went through the Tsushima Strait to the Sea of Japan, and depicted the Western coast of Hokkaido. They discovered a small Gulf of Patience. Given names are still present even in contemporary maps, for instance, capes of Senyavin and Soymonov. While transitioning through the Greater Kuril Chain, Krusenstern discovered four "Lovushki" islands. Then, while passing the Nadezhda Strait, the Krusenstern's crew reached the Cape Patience where it started shooting the way to Cape Levenstern, overall, 900 kilometres. Then they discovered the Northern Strait, the capes at the entrance and at the exit of which received names "Elizabeth" and "Maria" correspondingly. Near with the Northern access to the Amur Liman, the water depth was not significant, and Krusenstern concluded that Sakhalin was a peninsula. Participants of the first Russian circumnavigation conducted different oceanographic observations. They discovered the Equatorial Counter Current in Atlantic and the Pacific, measured the temperature difference at depths up to 400 m and determined its specific gravity, clarity and colour. They also found the reason behind the Milky seas effect and collected numerous data on atmospheric pressure, and tides in several areas of the oceans.
