Hawaii has a state-of-the-art sightseeing submarine, the Atlantis submarine, which can be 100 feet deep into the sea. For those who can't dive deep, it's a good choice to take a submarine to the underwater world. The submarine can accommodate up to 48 people. Each of the left and right rows of visitors has a glass round window in front of each other to watch the underwater world. Most of our submarines are Japanese tourists, so the commentator directly explained the Japanese in full. Fortunately, each passenger is also equipped with a pair of headphones. The Chinese mode is optional. During the submarine's march, the current status of the seabed will be heard in the headphones. explain. In the past 100 years, the natural coral reefs along the coast of Waikiki have disappeared. In order to provide a good living environment for marine life, Atlantis has also placed artificial reefs on the seabed, due to the perennial seabed. Many mosses and attachments have accumulated on it, and many tropical fish have migrated among them. When the submarine reaches a depth of 24 meters, a wreck of the hull is displayed in front of everyone. This is the San Pedro, a Korean fishing boat that sank in 1996. At the deepest 30-40 meters, the remains of the plane falling over the Pacific Ocean are clearly visible. Of course, it did not crash here, but was purchased by the Atlantis Submarine Company and placed on the bottom of the water. There is also a diver who walks freely like a tropical fish between the wreckage, sometimes waving at us, and sometimes playing with the fish, letting you shout the harmony and beauty of Hawaii. The sea is full of life except sand. They form a harmonious biological chain and live peacefully here.
