Distribution of water-column REE measurements

Symbols mark the location of water column profiles.  Colour denotes the depth of the deepest sample and give some indication of the extent of sampling at that site. A map of La is given to represent the full range of REE as well as a map for Nd which there is a greater range of data available.
