GLOBALIZATION OF COASTAL ZONE FUNCTION ACROSS MULTIPLE SPATIO-TEMPORAL SCALES

The LOICZ project is assessing the role of the coastal zone (CZ) in global fluxes of C, N, and P by linking, integrating and extrapolating scattered datasets at scales of 1-1000 km. Global trends must be identified from combinations of data sets with both natural and human-induced variablilty at scales from subannual to millennial. The approach combines standardized, comparable compilation of available CZ biogeochemical budgets with determination of systematic relationships to environmental variables. Globally available datasets in a gridded coastal database are used to generate a coastal typology (multidimensional similarity classification) by clustering. The method is simple, robust, and applicable over a wide range of data types, spatio-temporal resolutions, and environmental conditions. It can be refined by sub-grid scale parameterization, addition of variables, and/or use of nested high-resolution studies for calibration. Time-dependent information can be stored within the grid-cell database structure or used to generate successive scenario 'snapshots' for change analysis and identification of opportunities for space-for-time tradeoff analysis. The developmental emphasis is on versatility, flexibility, and broad applicability to the exploration of multiscale spatio-temporal relationships.
