Summary of the geographical, temporal and water quality distributions of the GLORIA samples. (a) Dots mark the ___location of each sample and the histograms on the edges of the map show the longitudinal and latitudinal distributions of the dataset. (b) The earliest samples were collected in 1990 and the sampling effort has been steady since 2001. (c–f) Histograms of log-transformed water quality attributes illustrate the extreme range of values and their typical log-normal distributions.
