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.

Trace metals are one of the most serious pollutants in tropical seagrass meadows given their persistence and toxicity. Whereas quantity is frequently measured, there no information on spatial extent metal pollution these systems. Here, we use an island Indonesia (Barang Lompo) as a model system to study impact radius two major eight trace sediment leaves. We provide evidence for exponential decay both index concentrations with increasing distance from (k = −0.01 −0.08 m–1). Consequently, approximately 100 m around island. The comparative analysis species further revealed interspecific differences loads. This highlights importance assessing addition its quantity.
