2. The Importance of Dokdo’s Location
Dokdo’s importance comes from its location.
Unlike the Yellow Sea and the South Sea, Ulleungdo and Dokdo are nearly the only islands in the East Sea. While the islands of the Yellow Sea and South Sea are close to the coast, Dokdo is far from any land. The East Sea is surrounded by Korea, Russia, and Japan. Dokdo is located in the middle of the East Sea.
○ Let’s examine the importance of Dokdo’s location in terms of the East Sea’s marine resources.
Among fish, some like cold water and some like warm water. The areas where warm and cold ocean water meet are full of plankton and fish.
There are a lot of fish around Ulleungdo and Dokdo. This is because the water is clean, and plankton, which the fish eat, is plentiful. It is at this location where the cold water current from North Korea meets the warm water current from the East Sea.
■ Let’s examine the rich resources surrounding Dokdo.
○ Let’s examine the importance of Dokdo in relation to the development of hydrate gas in the East Sea.
In 2010, Korea’s number one and number two exports, semiconductors and ships, made profits similar to Korea’s imports of crude oil and natural gas, which are the country’s primary energy resources.
The amount of major product exports and energy imports in dollars for 2010
Main Exports | Semiconductors | $51.5 billion | $98.6 billion |
Ships | $47.1 billion |
Major Imports | Crude Oil | $68.7 billion | $90.5 billion |
Natural Gas | $21.8 billion |
Hydrate gas is a solid form of energy created when a natural gas called methane combines with cold water deep in the ocean. It is similar in shape to dry ice, and since it burns easily when touched by flame, it is known as “burning ice.” The entire world is working to develop hydrate gas as the energy of the next generation.
○ Let’s take a look at the importance of Dokdo through the East Sea’s lighthouse and its keeper.
During the Three Kingdoms period, the waters around Dokdo served as a transport route for ships from Balhae and ships of Yeojin people to trade with other countries.
Today, the Dokdo lighthouse plays an important role in guiding passing ships.
Ulleungdo and Dokdo are both important militarily. South Korea built a communications base on Dokdo that can identify the location and movement of Russian, North Korean, and Japanese ships.
