Abstract Macroalgae are important primary producers in the coastal ocean, and they release a large fraction of their net production as dissolved organic carbon (DOC). It is assumed that much this DOC recalcitrant results sequestration amounts carbon. We lack sufficient knowledge about bioavailability material role other sinks such photooxidation. conducted dark remineralization photooxidation experiments on derived from an abundant brown macroalga quantified amended was remineralized by both processes. The ranged 14% to 99% significantly negatively correlated with its phenolic content. Upon exposure light, biologically compounds were quickly oxidized CO 2 , indicating sink for macroalgal DOC. These especially macroalgae cultivation being considered sequester atmospheric .
