Description

technical field [0001] The present invention relates to the technical field of marine engineering, and more specifically, to a seabed ocean current simulation device and a control method thereof. Background technique [0002] Compared with surface ocean currents, deep ocean currents mostly refer to seawater movement below 1,000 meters above sea level. Although it is difficult to observe the surface, due to the ocean conveyor belt effect, deep ocean currents have a long-term impact on the world's climate change. Scientists believe that, The influence factors of the ocean on climate change on a time scale of more than 10 years should be found in the deep sea. Deep ocean currents promote material exchange between deep ocean bottom currents and ocean surface water, promote surface water cooling and carbon dioxide absorption, and have a decisive impact on regulating global climate change and global ecosystems. On the other hand, the change of currents at the bottom of the deep s...
