I. Marine scientific research
It is a knowledge system that studies the natural phenomena, properties and changing laws of the ocean and related to the development and utilization of the ocean. Its research object is the ocean that accounts for 7 1% of the earth's surface, including seawater, substances dissolved and suspended in seawater, creatures living in the ocean, seabed sediments and seabed lithosphere, as well as the atmospheric boundary layer and estuary coastal zone on the sea surface.
The research field of marine science is very extensive, including the basic research of physical, chemical, biological and geological processes in the ocean, as well as the development and utilization of marine resources and the applied research of marine military activities.
Second, marine development.
With the development of social economy, the value of the ocean has been paid more and more attention by human beings, and people have developed and utilized it from different angles. In this process, more and more wastes are produced, and most of these wastes eventually enter the ocean directly or indirectly. When the discharge of these wastes and sewage reaches a certain limit, the ocean is polluted.
Such as marine oil pollution, marine heavy metal pollution, marine thermal pollution, marine radioactive pollution and so on. Pollution of the sea area will damage marine life, endanger human health, hinder human marine production activities, damage the quality of seawater use, and cause damage to the beautiful environment.
Three. fishing ground
Fishery refers to the social production department that catches and breeds aquatic animals such as fish and aquatic plants such as algae to obtain aquatic products. Generally divided into marine fisheries and freshwater fisheries. Fishery can provide food and industrial raw materials for people's lives and national construction.
Social production departments that develop and utilize water areas, collect and fish and artificially breed various aquatic animals and plants with economic value, so as to obtain aquatic products. Is an important part of agriculture in a broad sense. According to the water area, it can be divided into marine fishery and freshwater fishery; According to the production characteristics, it is divided into breeding and fishing.
