Figure 1: Maps of the environmental variables derived for the EEZ classification (Depth, Mean orbital velocity, Wintertime SST, Annual mean solar radiation, Annual Amplitude SST, Spatial gradient SST, Tidal currents, Slope)

Text description

A map of the EEZ is shown for each variable. The range for each variable is depicted by using colour to express the value. Variables and their data range were as follows: Depth (0 - 10,000 m ), Orbital Velocity (0 - 2478 mm/s), Wintertime SST (0.005 - 40 °C), Annual Mean Surface Irradiance (90 - 250 W/m²), Annual Amplitude SST (0.000017-5 °C), Spatial Gradient SST (0.000003 - 0.2 °C), Depth Averaged Maximum Tidal Current (0 - 3.2 m/s) and Slope Value (0 - 0.999851). Generally speaking, the EEZ varies significantly in depth and slope due to a number of continental shelfs, orbital velocity is higher in proximity to the coastline, tidal currents are influenced by coastline and changes in seabed slope and water temperature rises as you move north and/or shallower waters.
