Principal component analyses (PCA) of the abiotic parameters for the glacial turbid Lake FAS 3 and the clear Lake FAS 4. Percentages indicate amount explained by the individual PCA axes. (a) Ordination of the samples; (b) ordination of the environmental parameters. Note, that when weather conditions are not included in the PCA of the abiotic parameters, the separation of the two lakes and the position of the environmental parameters remain largely the same, while the individual samples within each type of lake are ordinated closer together. Turb, turbidity; MAAs, mycosporine‐like amino acids; Cond, conductivity; Temp, temperature; for all other abbreviations see Tables 1 and S1.
