Seagrass is valued for its ability to absorb carbon, its role in the oceanic carbon budget significant as it deposits considerable amounts in below-ground tissues, with larger seagrass species having greater capacity for accumulation of carbon due to the relatively slow turnover at the roots.
Global climate change resulting from carbon emissions, is accelerating the loss of seagrass habitats and causing decline and disturbances.
Seagrass meadows play an vital role in coastal zones and provide the ecosystem with important functions, including feeding coral reefs and marine life, protecting smaller animal species, and sheltering organisms.
Algae that cover seagrass leaves, providing nutrition for the fauna itself, constitute an important link between terrestrial and other marine habitats.
Carbon affects temperatures, acidification and changes in currents, interfering with ecosystem flow.
Unlike coral reefs which produce more carbon than they consume, seagrass reacts differently to the cycle.
Depending on the processes that occurs within it as a result of carbon cycle and in relation to other ecosystems, it reflects its high rate of carbon trade.
Global warming will inevitably lead to decreased efficiencies in sequestering carbon, resulting in the reduction of nutrient supply to deeper ocean layers. This will reduce ocean’s ability to uptake carbon dioxide, contributing to oceanic acidification.
