From: Methyl iodine over oceans from the Arctic Ocean to the maritime Antarctic

Box-and-whisker plots of CH3I concentrations in ocean origin (OO), land origin (LO) and Antarctic origin (AO) samples with CO concentration (a) below or equal to 150 ppbv and (b) above 150 ppbv during the CHINARE 11/12 and the CHINARE 12. The lower and upper boundaries of the box represent the 25th and the 75th percentiles, respectively; the whiskers below and above the box indicate the minimum and maximum, respectively; the line within the box marks the median; the dot represents the mean.
