Missing the forest for the trees: Do seaweed ecosystems mitigate atmospheric CO2 emissions?

The paper evaluates whether seaweed ecosystems mitigate CO2 emissions by analyzing net ecosystem production and export, finding they may act as carbon sources and caution against relying solely on NEP for mitigation.

Inorganic and black carbon hotspots constrain blue carbon mitigation services across tropical seagrass and temperate tidal marshes

The paper assesses the impact of black and inorganic carbon on blue carbon mitigation in seagrass and salt marsh ecosystems, finding higher constraints in seagrass due to greater carbon fractions.

Anthropogenic marine debris and its dynamics across peri-urban and urban mangroves on Penang Island, Malaysia

The paper assesses marine debris distribution and dynamics in urban and peri-urban mangroves on Penang Island, Malaysia, finding higher debris retention in urban areas and sorting towards coastal edges.

Blue carbon sequestration dynamics within a tropical seagrass sediment: Long term incubations for changes over climatic scales

The paper tests assumptions about blue carbon sequestration in seagrass sediments using long-term incubation experiments, finding significant POC loss and potential methanogenesis.

Carbon stocks of coastal seagrass in Southeast Asia may be far lower than anticipated when accounting for black carbon

The paper measures black carbon fractions in seagrass meadows and finds they are higher than predicted, significantly contributing to organic carbon content.
