Ocean carbon pump

The exhibit introduces the simulation of the biological and microbial carbon sequestration processes in the ocean through a pinball machine, in order to understand the principle of the "ocean carbon pump" carbon sequestration process. 1. Press the start button to activate the device. 2. The device automatically activates the CO2 ball and begins simulating the carbon sequestration of the ocean carbon pump, observing the movement transition of the ball; 3. Follow the transition steps of the ball and watch the knowledge animation of the corresponding area; one Biocarbon pump: refers to the process by which marine phytoplankton absorb surface carbon dioxide through photosynthesis, forming particulate organic carbon (such as biological debris and feces), which is then transported to the deep sea through sedimentation. This carbon is then deposited or decomposed on the seafloor, resulting in carbon sequestration for over a hundred years. It is the "vertical fast track" of the carbon cycle. two Microbial carbon pump: refers to the process in which marine microorganisms (bacteria, archaea, etc.) convert dissolved organic matter into inert dissolved organic carbon. This type of carbon is difficult to biologically utilize and can persist in the ocean for thousands of years, serving as an "inert transformation warehouse" for the carbon cycle.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
