Fig. 3: Per-area posterior mean estimates of blue carbon associated with subtidal kelp communities across Canada’s coastline.

Panels depict the posterior mean estimates of the (a) carbon stocks (Mg C ha-1), b carbon production (Mg C ha-1 yr-1), and (c) carbon export (Mg C ha-1 yr-1) capacity of subtidal kelp communities on Canada’s three coasts. Stacked bar plots show the summed posterior means across kelp species and coasts according to Bayesian hierarchical models, weighted by the relative abundance of kelp species on each coast.
