Fig. 1: Mean annual blue carbon sequestration potentials.

a, Global map of mean annual blue carbon sequestration potentials by country. b, Bar chart of the five countries with the largest and smallest mean annual blue carbon sequestration potentials. Mean national carbon sequestration potentials are based on spatial ecosystem coverages and mean global net sequestration rates, both per ecosystem type. Error bars in b represent ±1 s.e.m. of global carbon sequestration rates.
