Abstract

The invention discloses an ocean acidification research experiment device. The experiment device is characterized by consisting of a mixed gas preparation device and a tide simulator, wherein the mixed gas preparation device can quantitatively control the content of CO2 in air and inputting the air into the tide simulator, and the tide simulator can simulate the environments of ebb and flow of natural oceans to the limit and can restore natural environments as far as possible. The ocean acidification research experiment device has a simple structure, a smart design and reasonable layout, can simulate the tidal movement of oceans and can accurately control the content of CO2 dissolved in seawater.

Description

technical field [0001] The invention relates to an experimental device, in particular to an experimental device for ocean acidification research. Background technique [0002] In 2003, ocean acidification ( Ocean Acidification ) appeared for the first time in Nature. Atmospheric CO 2 Volume fraction continues to rise, leading to ocean uptake of CO 2 The amount of (acid gas) is increasing, and the pH value of seawater is decreasing, which is caused by atmospheric CO 2 The process of increasing the acidity of seawater due to the increase in volume fraction is called ocean acidification. Since the industrial revolution, the ocean has absorbed about one-third of the carbon dioxide emitted by humans, causing the average pH of the surface seawater to drop from 8.2 at the beginning of the industrial revolution to the current 8.1, according to the prediction of the Intergovernmental Panel on Climate Change (IPCC) Therefore, by 2100, the average pH of seawater will drop by abo...
