Report Map on the Hydrogeographic Work of Expeditions to the Eastern Ocean and by Squadron Ships in the Eastern Ocean for 1898 and Preceeding Years


Hydrographic maps mainly serve the needs of navigators and mariners. Other uses include fishing, oceanography, and underwater prospecting. Hydrographic mapping was highly developed in 19th-century Russia, where it was carried out by the Ministry of Marine to create and constantly update navigational charts. This map is from a larger work entitled Sobranie otchetnykh kart gidrograficheskikh rabot (Collection of Report Maps of Hydrogeographic Work and Maps Indicating Shipwrecks for 1898 in the Black Sea, Sea of Azov, Caspian Sea, White Sea, Baltic Sea, and Parts of the Eastern Ocean and Arctic Ocean, and Lake Baikal). The symbols on the map indicate coastlines that had been examined, coastlines that had not been inspected from the sea, and measurements taken in 1898 and in previous years. Noted on the map are islands, bays, straits, capes, underwater rocks, and population centers. The supplemental map in the upper left shows the work of hydrogeographic survey parties in the mouth of the Amur River.
