aRegions are named for the closest land body or ocean region
bAll data are mean total Ag concentration presented in μg/gww ± standard error with minimum and maximum values in ( )
cThis region had whales with nondetectable Ag concentrations. One-half the detection concentration (0.04 μg/gww) was used in the analysis
