Lateral carbon fluxes and CO2 evasion from a subtropical mangrove-seagrass-coral continuum

Anirban Akhand et al.

Summary: Mangrove, seagrass, and coral habitats in tropical and subtropical regions are interconnected and have varying effects on CO2 dynamics and air-water fluxes. Different habitats contribute differently to atmospheric CO2, and biogeochemical processes along coastal areas play a key role in carbon cycling.

Global Trends in Air-Water CO2 Exchange Over Seagrass Meadows Revealed by Atmospheric Eddy Covariance

Bryce Van Dam et al.

Summary: Coastal vegetated habitats such as seagrass meadows play a crucial role in mitigating anthropogenic carbon emissions by sequestering CO2 as blue carbon. This study highlights the complex interactions between air-water CO2 exchange and organic carbon storage in seagrass meadows, with a focus on global scale patterns and physical drivers influencing CO2 fluxes. The findings underscore the need for a comprehensive approach to carbon assessments in coastal ecosystems, taking into account both biological and physical factors.

Coast-wide evidence of low pH amelioration by seagrass ecosystems

Aurora M. Ricart et al.

Summary: The study demonstrates that seagrass ecosystems can ameliorate low pH conditions over extended periods of time, with stronger effects observed during the spring and summer seasons, especially in higher latitude meadows. These findings have important implications for the conservation and management of coastal ecosystems.

Alkalinity cycling and carbonate chemistry decoupling in seagrass mystify processes of acidification mitigation

Cale A. Miller et al.

Summary: This study investigates the impact of bioremediation methods on acidification by comparing different seagrass pools. The results suggest that habitats with mixed photosynthesizers have less decoupling between pH and aragonite saturation state.

Technical note: Interpreting pH changes

Andrea J. Fassbender et al.

Summary: The number and quality of ocean pH measurements have significantly increased in recent decades, but comparing pH changes across domains with different initial pH values can be misleading. It is recommended to use [HC] in addition to pH when describing such changes.
