Notes.

Environmental predictors: SST_m, mean sea surface temperature; SST_min, minimum sea surface temperature; SST_max, maximum sea surface temperature; Chl-a_m, mean chlorophyll-a concentration; Chl-a_min, minimum chlorophyll-a concentration; Chl-a_max, maximum chlorophyll-a concentration; D, depth; S, slope, D₂₀₀, distance to the 200-m isobath
