Purpose & Scientific Principle
The exhibits use an interactive form of machinery and multimedia to quantitatively demonstrate the results of acidification caused by large amounts of carbon dioxide entering the ocean, allowing the audience to understand the impact of different degrees of ocean acidification on marine life and ecology.
How to Operate
Ocean acidification means that seawater is gradually becoming acidic due to the ocean absorbing excess carbon dioxide from the atmosphere. The increase in seawater acidity will change the chemical balance of seawater, posing a huge threat to various marine organisms and even ecosystems that rely on the stability of the chemical environment.
Ocean pH is a measure of the acidity or alkalinity of the ocean. The ocean is weakly alkaline due to the hydrolysis of weakly acidic anions, and its pH value generally varies between 8.0 and 8.5. The pH value of ocean surface water is about 8.2. However, since the industrial revolution, more than 1/3 of the carbon dioxide released by human activities has been absorbed by the ocean, and the pH of seawater has dropped by 0.1, which also means that the acidity of seawater has increased by 30%. This phenomenon in which seawater gradually becomes acidic as the ocean absorbs excess carbon dioxide from the atmosphere is called ocean acidification.
As the acidity of seawater increases, the chemical balance of the ocean's own carbonates is broken, posing a huge threat to various marine organisms and even ecosystems that rely on the stability of the chemical environment. From bacteria to fish, many organisms have been shown to be negatively affected by ocean acidification. The reduction or demise of marine germplasm resources caused by ocean acidification will affect the balance of the entire marine ecosystem along the food chain. At the same time, the accumulation of pollutants and toxins will have a negative impact on human marine food and increase human health risks.

In order to fit the theme of the exhibits, a large screen is set up to display marine ecological scenes, and a push rod interaction method is used, combined with multimedia display, to allow the audience to understand the changes in marine ecology under different ocean pH values.
The push rod interactive design is adopted to enhance the interactivity of the exhibits and make them more attractive to young people. Combined with large-screen display equipment, compared with traditional missionary knowledge display, it is more in line with the knowledge needs of young people.
