A brief history of oceanography;

Understanding the history of the ocean begins with the production activities in coastal areas and at sea. Ancient humans already had some geographical knowledge about the ocean.

However, it was not until 65438+ 1970 that Challenger, organized by the Royal Society, completed the first global marine scientific expedition, and oceanography gradually became an independent discipline. Since 1950s and 1960s, oceanography has made great progress and formed a comprehensive marine science.

From ancient times to the end of 18, it is the accumulation period of marine knowledge and the embryonic period of oceanography.

In ancient times when science was underdeveloped, people's understanding and exploration of marine natural phenomena mainly depended on insufficient observation and simple logical reasoning. Although it was limited to grasping some properties of the ocean intuitively and generally at that time, it also put forward many wonderful opinions.

For example, Thales in ancient Greece believed that water was the source of all things, and the earth floated in the boundless ocean. In the Book of Songs written by China from 165438 to the 6th century BC, it has been recorded that rivers live in the sea.

In the 4th century BC, Aristotle, the most learned thinker in ancient Greece, described and recorded 170 kinds of Aegean animals in zoology. In the first century A.D., Wang Chong of the Eastern Han Dynasty scientifically pointed out the corresponding relationship between tidal movement and moon movement.
