According to foreign media reports, the antikethira device is one of the most amazing discoveries in modern times, which has sunk into the sea for thousands of years. It is the oldest complex gear device discovered so far. Based on its structural complexity, it is sometimes called the first analog computer in the world. Its design is based on the period prediction of Babylon arithmetic series.

3. Ancient cities under the sea
What causes the whole city to sink to the bottom of the sea? The sea level rise caused by the ice sheet and other factors makes the city gradually sink to the bottom of the sea. With the help of modern advanced science and technology, we can rediscover and study these submarine ruins. One of the most famous examples is the city of thonis, which sank into the seabed of Egypt. Its history can be traced back to thousands of years ago and was discovered during the submarine survey in 2000.

6. Pirate ships and cannons
In 1718, the legendary "Blackbeard" pirate ship ran aground in the Beaufort Sea area and finally sank into the sea. In 1966, the wreckage of the pirate ship was recovered and found. In 2013, the Department of culture and resources of North Carolina claimed to find the "Blackbeard" pirate ship cannon, which weighed more than 907 kg.
7. New shark species
During a two-month fishery survey in the Indian Ocean in 2012, scientists fished hundreds of sharks from the seabed, including at least eight new species.
8. Jurassic microorganism
In 2012, scientists found Jurassic microbes in the deep sea. They barely survived, and it was difficult to get enough oxygen to maintain metabolism. It was difficult to believe how they survived.
9. 61 tons silver brick
In 2012, the marine survey team salvaged 61 tons of silver bricks, worth US $36 million, in the waters of Northern Ireland. According to analysis, these silver bricks came from the British SS gairsoppa freighter in 1941, which was torpedoed and sunk to the bottom of the sea by the German Nazis.
10. Mysterious Octopus sea monster
For centuries, it has been recorded that fishermen have caught mysterious Octopus sea monsters in the ocean, and even some octopus are more than 13 meters long. The first time that living giant octopus was found was in 2001, and the video of adult giant octopus was taken in 2012.
