Figure 17: Classification of the EEZ using the continuous colour scheme based on the principal components of the eight variables used to define the classification

Text description

A map of the EEZ displays a colour scheme based on principal component analysis on the 290 classes generated by non-hierarchical classification. Each class was assigned varying levels of red, green or blue colour based on the value of the first three components in the analysis. Bluer areas are deeper, with higher slopes and lower tidal current and mean orbital velocity. Redder areas have higher SST winter values and annual mean surface solar radiation. Greener areas are associated with higher slopes and higher SST gradients.
