The Marine Microbial Carbon Pump (MCP) theory proposes a novel mechanism for long-term carbon sequestration in the ocean, wherein microbial processes convert labile dissolved organic carbon (LDOC) into recalcitrant dissolved organic carbon (RDOC). This review synthesizes recent advancements in technologies aimed at enhancing carbon sinks based on the MCP, with a specific emphasis on coastal ecosystems. Through a structured literature review, the authors evaluate the mechanisms of action, key environmental regulatory factors, and negative emissions technologies associated with utilizing the MCP to bolster the ocean carbon sink.
