Figure 2.11. GIS classification of surface waters and spatial distribution of 5 clusters of 20
environmental data layers in various seasons in NW Atlantic Ocean. The major data layers that were
used for this classification include air temperature and pressure, wind speed, sea depth, slope and aspect
of sea floor, sea surface temperature and salinity and sea temperature and salinity at 30m of depth (Huettmann and
Diamond 2001). Images are courtesy of Falk Huettmann, Simon Fraser University, Canada
