The purpose of this study is to identify the characteristics of naming on marine geographical features around the Korean peninsula by western countries during 1787 through 1910. In order to do this, firstly, we collected 11 journals of voyages, 5 survey reports, and 45 nautical charts, and 3 gazetteers published by Britain, France, Russia, and the U.S. Secondly, we chronologically summarized the history of hydrographic survey around the Korean peninsula based on these sources. Thirdly, 118 marine geographical names were extracted and the origins of them were inferred. Lastly, we classified 118 marine geographical names into four types: descriptive, emotive, shift, and commemorative (person, ship, non-living entity) in terms of name origins. Results were as follows. Firstly, the hydrographic survey of the Korean peninsula began in France in 1787, and was actively conducted by Britain, United States and Russia. The east coast was explored in detail by Russia, the south coast was conducted by UK, and the west coast was surveyed by France, UK, and the United States. Secondly, for naming types, commemorative person type (39%) was the most preferred one, followed by commemorative ship (21%, descriptive (13%), shift (11%), non-living entity (8%), and emotive (4%) types. Thirdly, western countries preferred commemorative type in naming marine geographical features, in particular, Russia and U.S were more concentrated in commemorative type than U.K and France were. Lastly, France and U.S showed decreasing trend of naming marine geographical features after 1877, on the other hand, U.K and Russia showed an increasing trend.
