Fig. 2: Per-area estimates of blue carbon associated with subtidal kelp species in Canada.

From: A blueprint for national assessments of the blue carbon capacity of kelp forests applied to Canada’s coastline

Fig. 2

Panels depict the posterior mean estiamtes of the (a) carbon stock (Mg C ha-1) and (b) carbon production (Mg C Ha-1 yr-1) capacity of kelp species across Canada’s three coastlines (Pacific = purple; Atlantic = green; Arctic = blue) according to Bayesian hierarchical models. Posterior mean estimates (and 90% credible intervals) are shown for each species, representing the average posterior predictive distribution conditional on the observed data and prior information. The inner and outer bars show the credible intervals representing the range of values within which the true mean estimates are likely to occur with 80% and 90% probability based on the final models. Kelp species include: Macrocystis pyrifera, Nereocystis leutkeana, Costaria costata, Agarum clathratum / Neoagarum fimbriatum, Laminaria digitata / Hedophyllum nigripes, Laminaria solidungula, Pterygophera californica, Pleurophycus gardneri, and Saccharina latissima.
