Gageodo
Gageo-do, also known as Soheuksan-do or Little Heuksan-do due to its location near Heuksan-do, is an island in the Yellow Sea. It is within the administrative boundaries of Sinan County, Jeollanam-do, South Korea, and is connected by the Namhae Star ferry to the city of Mokpo. The island's 9.2 km² are home to about 470 people.
Gageo-do is meteorologically significant, due to its location near the southern limit of the Yellow Sea Cold Current. In 2005, the South Korean government announced plans for a marine science base on the island.
