Ocean carbon sequestration through kelp, seagrass, and seaweed photosynthesis

• Coastal vegetated habitats (seagrass for example) can sequester between 2 to 4.5 metric tons of carbon per hectare per year. • Kelp forests can capture 3.6 metric tons of carbon per hectare during a typical growing season. Kelp is one of the fastest growing plants in the world (up to 2 feet/day)
