Tides in Korea

I went to field trip to Sumjin River in South Korea in summer 2002.

Sumjin River, Korea in 2002

Since Korea is small country, you can see the ocean within 4 hours no matter where you live. Also, ebb-flood tides are so strong that we can observe a huge area of subtidal zone coming out of water twice a day.

I remember here clearly because I had never seen such a beautiful and a broad subtidal sediment.
