Abstract Macroalgae beds are extensive and productive marine benthic vegetated habitats globally, occurring in nearly 28% of coastal worldwide. These forests may be important carbon sinks but there very limited in-situ assessments their stocks. In this study, we assessed the blue stocks (aboveground belowground) typical macroalgae SW Atlantic coast by comparing shallow (< 2 m) subtidal environments with without presence macroalgae. We estimated a total ecosystem stock (TECS) 1.64 ± 0.24 Mg C ha −1 on beds, which was average 30% higher than areas (1.14 0.16 ). The differences between were attributed to aboveground macroalgal biomass (0.49 0.23 ), corresponded Sargassum sp. (Phaeophyceae) most representative studied (59%), contributed proportion Using satellite imagery, an area 527 along stretch 410 km Eastern Marine Ecoregion Brazil, representing TECS 869 128 C. Nearly 45% these currently within protected region, although they hold value for climate mitigation, remain largely unrecognized conservation planning Atlantic.
