Ascension Island Valuation of carbon storage, sequestration and social cost by benthos in Ascension Island’s EEZ 2019
As it grows and reproduces life on seabeds (benthos) accumulates carbon and is a major source of carbon storage, termed ‘blue carbon’. Through long-term aging, burial and ultimately conversion to rock, benthos removes carbon from cycling (between air and water), referred to as sequestration. We used seabed mapping, seabed camera imagery and collections of seabed life to estimate how much carbon is being stored by benthos in water shallower than 1000 m deep in Ascension Island’s Exclusive Economic Zone. This essentially comprises of coastal waters around Ascension Island and three seamounts (Harris-Stewart, Grattan and Un-named).
