Typical of them is the research into applying undersea water in the depth of 900 meters to various fields.

The undersea water in the East Sea of Korea has no pollutant. It is rich in the content of nutritive substances and its temperature is low.

The research for pumping up this water by vessel or in seashore went over from theory to practice.

And primary- and second-stage processing technologies of undersea water were established to use it in the stock raising and the production of medicines and cosmetics.

Besides, such marine technologies as marine ecological environment control, construction of industrialized indoor cultivation ground, sea culture and fish farming, desalinization and artificial sea water making were introduced into practice.
