Fig. 11: RMSE profiles of global ocean.
From: A source-weighted Benthic minus Planktonic radiocarbon method for estimating pure ocean water age
a shows the RMSE value \(\left(\root{2}\of{\frac{{\sum }_{{\boldsymbol{1}}}^{{\boldsymbol{n}}}{\left({\boldsymbol{BwP}},{\boldsymbol{n}}-{\boldsymbol{Iage}},{\boldsymbol{n}}\right)}^{{\boldsymbol{2}}}}{{\boldsymbol{n}}}}\right)\) between Iage and BwP age with varying dye (purple), nominal BwP age using dye at the LGM (red), and nominal BwP age using dye at the PI (yellow). b is same as (a), but for RMSE value as a fraction of the absolute Iage.
