Marine science is the study of the natural phenomena, properties and changing laws of the ocean, as well as the knowledge system related to the development and utilization of the ocean. Its research objects are the oceans that account for 71% of the earth's surface, including seawater, substances dissolved and suspended in seawater, living organisms in the ocean, seafloor sediments and lithosphere, and the atmospheric boundary layer and estuary coast . Therefore, marine science is an important part of earth science.
In the solar system
Various natural phenomena and processes that occur in the world's oceans have their own characteristics, and marine scientific research also shows certain characteristics accordingly.
The history of mankind's understanding of the oceans began when people engaged in productive activities in coastal areas and at sea. Ancient humans already had some geographic knowledge about the ocean. But until the 1870s,
The research system of modern marine science can be roughly divided into two parts: basic subject research and applied technology research. Fundamental disciplines are directly studying the natural phenomena and processes of the ocean as their research objects and exploring their development laws; applied technical disciplines are studying how to use these natural laws to serve humanity.
Natural processes occurring in the ocean can be roughly divided into four types: physical processes, chemical processes, geological processes, and biological processes according to their intrinsic properties. Each type is a system composed of many individual processes. The study of these four types of processes has accordingly formed four relatively independent branch disciplines in marine science:
School code and name [1]
The research on marine natural phenomena or a certain sea area has generally developed from traditional static qualitative description and simple causal analysis to dynamic quantitative analysis. It attaches importance to basic theory, field experiments and functional simulation research, and uses simplified and approximate simulation models and Mathematical models are used to reflect specific and complex natural entities, and experimental and numerical simulations and predictions are used to replace the estimation of the status quo.
The integration and penetration of various branches of marine science, and between marine science and neighboring disciplines, will
Marine science
More and more interdisciplinary research topics have emerged. Some fundamental topics, such as ocean-atmosphere interaction and long-term climate forecasting, marine ecosystems, material cycles and transformations in the ocean, the structure of the ocean floor, and the origins of the oceans and the earth, the origin of marine life, etc., all need to be addressed Further research and exploration.
