→ This is approximately 100 times that of all Canadian seagrass beds and saltmarshes combined1, around half of all carbon in Canada’s forest vegetation, and 10% of that in soils.2 Epstein, G., Fuller, S. [...] Globally, seafloor sediments are estimated This new study reports on to hold carbon stores greater than that of all the creation of the first high- soils on land.3 However, while management resolution predictive map of plans for coastal and terrestrial areas such as organic carbon stocks in surficial forests and wetlands often account for their role in mit. [...] The standing stocks on the Canadian seafloor, which could stock of organic carbon in the top 30 cm of help inform management of this critical but sediment is estimated to be 10.9  gigatonnes often overlooked ecosystem. [...] The areas with highest carbon density were small areas The organic carbon contained in seafloor within nearshore zones, including the inlets sediments has a major influence on global and fjords of British Columbia and parts of the carbon cycles and earth’s climate. [...] For example, a recent study appropriate management strategies to limit estimated that global fishing activities could the potential loss of carbon due to disturbance cause considerable remineralisation of seabed of the seafloor.
