1, marine science mainly studies the natural phenomena, properties and changing laws of the ocean, as well as its development and utilization. The research objects include seawater, substances dissolved and suspended in seawater, creatures living in the ocean, seabed sediments and lithosphere, as well as atmospheric boundary layer and estuary coastal zone on the sea surface.

2. Marine technology not only learns the basic knowledge and laws of the ocean, but also learns the basic theories and knowledge of marine high-tech and marine engineering, and accepts the basic training of new marine technologies.

3. Computer science and technology mainly studies the design and manufacture of computers, including the basic theories, skills and methods of computer software and hardware, the development and maintenance of computer systems and software, and the assembly of hardware.
