Appendix F. Results of Principal Component Analysis using average values of POC and PON concentrations, PO13C and PO15N values, and molar C:N ratio for all water quality stations combined. The most influential eigenvectors for PC 1 and PC 2 are highlighted in bold. Total variance explained by the model was 81% (50 and 31% for PC 1 and PC 2, respectively). PC 3 had an eigenvalue of 0.62 and was not retained for the analysis.
