Sediment Properties as Important Predictors of Carbon Storage in Zostera marina Meadows: A Comparison of Four European Areas (original) (raw)
Fig 5
Semi-log plots (log10[x+1]) showing the relationship between sedimentary % Corg and grain size.
The % Corg is presented with a log scale as it gave the best fit of the models. Grain size is shown as mean grain size (ɸ) and sediment particles < 0.074 mm (%) for Z. marina meadows (a and b) and unvegetated areas (c and d). The % Corg was positively linked to both sediment particles < 0.074 mm (%) (R2 = 0.91, P < 0.001) and mean grain size (ɸ) (R2 = 0.74, P < 0.001) for Z. marina meadows but for unvegetated areas only sediment particles < 0.074 mm (%) showed such relationship with % Corg (R2 = 0.42, P < 0.001).
