Seagrass Meadows

  • Daniel M. Alongi
Part of the SpringerBriefs in Climate Studies book series (BRIEFSCLIMATE)


Seagrass meadows are intertidal and shallow subtidal habitats composed of up to 76 species of marine angiosperms and are important components of global estuarine and coastal ecosystems in boreal, temperate and tropical latitudes. Seagrasses are capable by their very existence of reducing the velocity of currents and attenuating waves to the extent that sediment particles and associated carbon can deposit on their surfaces and on the seabed. Rates of carbon sequestration in seagrass beds average 220.7 ± 20.1 g Corg m−2 year−1 with a median of 167.4 g Corg m−2 year−1. Seagrasses, on average, store carbon although apparently less than salt marshes and mangroves. Carbon stocks show a median value of 69.3 Mg Corg ha−1. Median above- and below-ground biomass are 0.264 and 0.540 Mg Corg ha−1, respectively, underscoring that nearly all seagrass Corg is stored in soil. Global Corg stocks range between 2.1 and 4.2 Pg Corg for soils and 75.5 and 151 Tg Corg for biomass. Assuming a soil profile one metre deep, the soil Corg stock rises to between 5.8 and 9.8 Pg Corg. Seagrass losses return to either the atmosphere or to the adjacent coastal ocean, or both, from 0.54 to 1.08 Pg CO2 equivalents annually. This range is greater than that for salt marshes and mangroves.
