This study aimed to estimate the amount of carbon sequestered by seaweeds, with the view of promoting the use of seaweed farms as carbon sinks. The goal of the CO2 Coastal Removal Belt (CCRB) was to establish both natural and man-made plant communities in the coastal region of southern Korea that will accomplish CO2 removal in the manner of a forest and which can be implemented along various spatial–temporal scales.
Site Selection Criteria:
An artificial reef populated by abundant seaweeds was chosen as a reference site. The longline system was built in coastal waters on the southern coast of Korea.
Cause Of Decline:
Nearly 0.7 million tonnes of carbon are removed from the sea each year within commercially harvested seaweeds. Although seaweed communities occupy only a very small area of the coastal region, they are essential because of their biotic components, valuable ecosystem services, and high primary productivity. The unique three-dimensional habitats of kelp forests also make them biodiversity hotspots in cold waters. Whereas some seaweeds have been cultivated for many centuries, others have traditionally been collected from natural stocks or “wild” populations. Unfortunately, some of these cultivated species are now in decline due, in part, to overharvesting.
