A MUTLIPLE SCALE ANALYSIS OF SPATIAL AND TEMPORAL PATTERNS OCCURING IN THE COASTAL ZONE USING GEOGRAPHIC INFORMATION SYSTEMS

We present a methodology that uses Geographic Information Systems (GIS) and statistical clustering techniques for comparing data across multiple spatial and temporal scales. For the coastal zone of the Australian region, we explored the functional response of available biogeochemical budgets to globally available environmental variables. We compared environmental variables aggregated at 30' resolution with local CNP budgets representing coastal systems of various sizes. The role of intra-annual variability in characterizing types of CNP budgets is explored by clustering experiments comparing the results of analyses using only average values with those including information on the range and variance of the variable data. This provides a means of incorporating some key aspects of temporal variation in an analysis based largely on static or averaged data.
