Regression lines relating metals to nutrients throughout the water column from studies conducted in the Sanctuary where r is the correlation coefficient for the regression line. Ni appears to be linearly correlated with Si at depths greater than 1000 m as described by a multiple regression equation.
| Ratio | Regression Line | r | Reference | |
| Cd:PO4 | [Cd nM] = (0.347 ± 0.007)[PO4 µM] - (0.068 ± 0.017) | 0.992 | Bruland, 1980 | |
| Cd:PO4 | ng Cd = -3.6 + 34.9 (µmol PO4) | 0.998 | Martin et al., 1980a | |
| Zn:Si | [Zn nM] = (0.0535 ± 0.0008)[Si µM] + (0.02 ± 0.09) | 0.996 | Bruland, 1980 | |
| Zn:Si | ng Zn = -12.1 + 3.98(µmol Si) | 0.992 | Martin et al., 1980b | |
| Ni:PO4 and Si | [Ni nM] = (0.95 ± 0.08)[PO4 µM] + (0.033 ± 0.001)[Si µM] +2.74 | 0.995 | Bruland, 1980 |
