Korea, which is bordered by the sea on three sides, has a coastline that extends 17,200km in total, which is considerably longer than many other countries in the world. The average depth of the West Sea is 44m, with the maximum depth measuring 103m. It has a large tidal range and has many tidal flats. The water temperature of the South Sea, with an average depth of around 100m, reaches over 30℃ in summer and does not fall below 10℃ in winter. On the other hand, the East Sea has a steep submarine topography with the ocean floor reaching 4,000m below sea level and the average depth measuring 1,530m. The water temperature remains stable around 1℃, while the salt concentration measures 34PSU. Because of these characteristics, facilities for obtaining deep seawater are being developed along the east coast by the local governments and private companies.
