A method for measuring marine biological carbon sequestration

Abstract

The invention discloses a method for measuring marine biological carbon fixation. The specific steps include classifying collected marine biological samples according to different species, decomposing them into different tissues and organs, drying the different tissues and organs, and calculating the amount of different tissues and organs of different species. Wet mass ratio and dry mass ratio, measure the carbon content of the sample before ashing, after ashing the sample, measure the carbon content of the sample after ashing, calculate the carbon content of the wet sample before and after ashing, and then calculate the carbon content of the wet sample according to the existing biological The existing carbon storage of marine organisms, the carbon storage of marine biological fishing removal, the carbon storage of marine biological deposition and the total carbon storage of marine organisms are estimated. The method of the present invention is simple and easy to operate, and can effectively estimate the carbon storage situation of marine organisms; at the same time, the carbon fixation capacity of different marine animals and the carbon deposition of marine animals are studied, and the species with strong carbon fixation capacity are screened out, which is marine The modular construction of pastures, carbon sink estimation and operation management provide scientific basis.

Description

technical field [0001] The invention belongs to the field of marine biology research, and in particular relates to a method for measuring carbon sequestration by marine organisms. Background technique [0002] The ocean is the largest carbon reservoir on Earth, with more than half (55%) of the planet's biogenic or green carbon captured by marine organisms. Because the respiration process of marine animals returns the carbon fixed by photosynthesis to the atmosphere, which is considered to weaken the efficiency of the marine biological pump, but in recent years, more and more studies have shown that marine animals play a role in ocean carbon movement and storage. have made significant contributions. The role of marine animals in ocean carbon sinks is mainly manifested in two aspects: on the one hand, they affect the transport and cycle of carbon in the ocean through their own physiological activities, and on the other hand, they play a role in sequestering carbon. It is wor...
