Therefore, the large-sized seaweed is a vitality force for carbon sequestration of offshore marine organism circles, provides a brand-new and effective carbon sequestration mode for solving the energy and environmental problems for human beings, and is highly valued by researchers at home and abroad.

In order to study the influence of the outbreak of green tide algae on the seawater inorganic carbon system and explain the reason of the large-scale outbreak of green tide algae, it is necessary to determine the biomass and the carbon fixation amount of enteromorpha. In order to determine the carbon fixation amount of the green tide algae tissue of the enteromorpha, the total biomass of the green tide algae which explodes every year is estimated according to the coverage area, the thickness and the biomass per unit volume of the green tide algae which explodes, and the carbon fixation amount of the green tide algae tissue is finally estimated by combining the carbon content of the green tide algae tissue.
