It is the world's first ice-sea observation tower on the 4th floor of the ocean floor and the 1st floor of the underwater building which is located about 1km from the coast and 10m deep.

When covered with drift ice, it becomes a tower to be built in the ice and under the drift ice can be observed at the bottom of the sea.

We can observe various ecology of marine organisms through seasons as well as drift ice in winter.

You can also observe the ocean floor at night.
