Ocean thermocline and halocline simulation device

Abstract

The invention discloses an ocean thermocline and halocline simulation device. The ocean thermocline and halocline simulation device comprises a thermocline and halocline simulation water tank, a thermocline and halocline water injection device, a temperature control box and a small-sized refrigerator, wherein the thermocline and halocline simulation water tank is respectively connected with the thermocline and halocline water injection device, the temperature control box and the small-sized refrigerator; a heating rod, a salinity sensor, a lower-layer temperature sensor and an upper-layer temperature sensor are arranged in the thermocline and halocline simulation water tank in sequence from bottom to top; and the thermocline and halocline water injection device consists of a freshwater tank, a drainage tube and water injection sponge. When the ocean thermocline and halocline simulation device is in use, firstly half the volume of salt water is put into the thermocline and halocline simulation water tank, then freshwater at the upper part is injected by the water injection device, and the temperature reduction of the freshwater at the upper part and the temperature rise of the salt water at the lower part are controlled by the temperature control box, so that a temperature difference is generated between the freshwater at the upper part and the salt water at the lower part; after the temperature is stabilized, an ocean thermocline and halocline layer on which temperature and salinity drastically change is formed at the junction of the freshwater at the upper part and the salt water at the lower part.

Description

technical field [0001] The invention relates to a marine environment monitoring device, in particular to a marine thermohalocline simulation device. Background technique [0002] In marine surveys, seawater temperature and salinity are one of the most basic parameters, which play an important role in marine environment research. In the on-site marine environment, in addition to large water masses and currents, there are also many fine structures, such as thermohaline and climatic layers with huge gradient changes in temperature and salinity at about 100-200 meters below the sea surface. The temperature difference of the water layer at the microscale of several centimeters in the vertical direction ranges from 0.1 to 3°C. Thermohaloclines are caused by double-diffusion convection at the interface between cold, fresh seawater above warm, salty seawater. Thermohaline is of great significance to the study of ocean microstructure and the safe navigation of underwater vehicles, ...
