Seasonal trends for alpha diversity indices in the Bedford Basin from 2014 to 2017. Chao1 diversity (a; with standard errors as defined for the Chao1 model for estimating richness), and Shannon diversity (b). Orange arrows indicate low alpha diversity during the spring and autumn blooms. Samples from the euphotic (1, 5 and 10Â m; cyan circles) and aphotic zone (60Â m; orange circles) are colour coded. Loess regression lines are fitted for each zone and the inflection points on the regression lines show a minimum in April/May and in October for both indices.
