Concentrations of WSOC and WISOC. Box and whisker plot of the concentrations of water-soluble organic carbon (WSOC) and water-insoluble organic carbon (WISOC) found on aerosol particles. Each box encloses 50% of the data with the mean value represented as an open square and the median value represented as a line. The bottom of the box marks the 25% limit of the data, while the top marks the 75% limit. The lines extending from the top and bottom of each box are the 5% and 95% percentiles within the data set, while the asterisks indicate the data points lying outside of this range (“outliners”). Boxes are color-coded to indicate paired samplings of WSOC and WISOC. The light green dashed lines encompass data from locations with low chl-a concentrations; the dark green dashed lines, those from locations with high chl-a concentrations. The solid blue fields highlight data from locations with high wind speeds. DOI: https://doi.org/10.1525/elementa.225.f5
