Abstract: [Objective] The ocean, as the largest “active” carbon reservoir on the Earth, plays a critical role in
global carbon cycling. Macroalgae contribute to this process through photosynthetic carbon fixation and the re-
lease of dissolved organic carbon (DOC) and particulate organic carbon (POC) via physiological metabolism.
Harnessing the carbon sequestration potential of macroalgae represents a vital pathway toward achieving the
“carbon neutrality” goal. [Progress] This review comprehensively examines the mechanisms by which mac-
roalgae enhance carbon sequestration, including the synthesis of biomass carbon through photosynthesis and the
release of DOC and POC. The review summarizes methods for assessing “short-term carbon sinks” based on
macroalgae cultivation yields, as well as techniques for evaluating “long-term carbon sinks”, such as the C/N ra-
tio, stable isotope analysis, spectral analysis, spectral analysis, multi-omics technologies, and relevant model
construction, etc. Additionally, the review analyzes the impacts of key environmental factors including temper-
ature, nutrient concentration, light intensity, salinity, and desiccation on the growth of macroalgae and their pho-
tosynthetic carbon fixation efficiency. [Prospect] By providing a multi-faceted perspective on the carbon sink
function, carbon sequestration mechanisms, assessment methods, and environmental factors influencing mac-
roalgae, this review aims to deepen the understanding of their critical role in marine carbon sinks and to offer
foundational insights and references for developing carbon sequestration and enhancement technologies.
