Review and Prospect of Potential High-resolution Detection Technologies for Ocean Carbon Sequestration

Abstract

In order to promote the accomplishment of the national carbon neutrality goal and enhance the international discourse power in the field of marine carbon sinks, this paper focused on high-resolution methods on the exploration of ocean carbon sink mechanism, covering biological and chemical detection methods and extensive applications. The results showed that marine refractory dissolved organic carbon pool played a significant role in carbon sink expansion, which put forward new challenges for high-resolution detection methods of dissolved organic carbon sink resources. Currently, high-resolution detection methods capable of tracking "fingerprint characteristics" mainly included flow cytometry and GeoChip functional detection, chemical detection methods, such as spectral and mass spectrometry as well as stable carbon isotope labeling technique that could realize the coupling between biological and chemical detection, were having crucial application prospects. With the stable carbon isotope labeling method as the link between biological traceability and chemical detection, all the technologies would have important application prospects.
