摘要
韓国は,経済水域に恵まれ沿岸域と海洋で活発な人間活動を進め経済発展を遂げてきた. しかし, 沿岸域では産業活動の発展とともに埋め立てが進められ, 干潟の減少, 海洋汚染, 藻場の消失, 沿岸域の荒廃などが進んだ. その上, 韓国南部では水不足も深刻である. このため, 政府は2000年から海洋深層水の資源利用に着目し, 2005年に海洋深層水研究センターや陸上施設などが完成した. これには韓国の国土海洋部が資金を供給し, 実際のプロジェクトは高城で進められた. 海洋深層水は水深300mと500mの2水深から1,100t/日取水し, 巨大水槽に貯留して使用に供されている. また, それぞれ近くの海岸から表層水も取水されている. この他, 大手企業のパナブルが7.5kmの取水管を設置して水深1500mから日量3000tの海洋深層水を取水している. 韓国の海洋深層水は, 様々な研究および開発に利用されている.
South Korea is blessed with a huge exclusive economic zone (EEZ) of oceans and coastal areas where we have developed human activities and present economical progress. Coastal oceans, wetlands and tidal flats have been reduced owing to increasing reclamation. Also, the shortage of freshwater is serious in South Korea. Accordingly, the government started to utilize deep ocean water (DOW) in 2000. Afterwards, infrastructures including the deep ocean water research center and the shore based facility were established in 2005. A five-year project, funded by the Ministry of Land, Transport and Maritime Affairs of Korea, began in Kosung using two types of DOWs pumped at a rate of 1,100 tons per day from depths of 300 m and 500 m and pooled into large tanks. Also, surface water is separately taken from the coast nearby. In addition, Ulleung-do deep ocean water factory owned by a private company, Panaburu, pumped 3,000 tons of DOW per day from a depth of 1,500 m through a pipe of 7,500 m in length. DOW is used for research and development of various purposes in South Korea.
