First, the professional definition is different.

1, marine science and technology

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, such as marine resources investigation, marine exploration and marine information processing technology.

2. major in marine science

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. For example: tides, El Nino, marine life and so on.

Second, the curriculum system is different.

1, marine science and technology

Introduction to marine science, chemical oceanography, physical oceanography, oceanography, application technology of marine remote sensing, principle and application of geographic information system, marine management information system, digital marine engineering, calculation and prediction of marine elements.

2. major in marine science

Introduction to marine science, biological oceanography, physical oceanography, marine geology, marine survey and observation technology, offshore oceanography, fluid mechanics, marine environmental biology and marine microbiology train the following professional directions: marine biology, physical oceanography, marine environmental science and marine biopharmaceuticals.

Third, the employment direction is different.
