Question
Evaporation and precipitation have a considerable effect on surface ocean salinity.
Figure 4A-2 is a global map of annual mean salinity. (This same figure appears in
Investigation 3A.) Mentally mark each major center of highest salinity with an “H"
and survey the map to identify regions of relatively low salinity.
