Seagrasses are a group of marine flowering plants that grow submerged in shallow marine and estuarine waters across the globe in both temperate and tropical regions. They are found on every continent except Antarctica and are often adjacent to or linked to mangroves and coral reefs, both geographically and through trophic interactions (Hemminga & Duarte 2000; Larkum et al. 2006). Seagrass beds are described as being one of the most productive ecosystems with mean global productivity estimates of 1012g DW C/m2/year (Duarte and Chiscano 1999) and in the Caribbean, total biomass rates range between 285 to >2000g DW C/m2/year have been reported (van Tussenbroek et al. 2014).
