Development of a data visualization and analysis tool to study the particle dynamics in the coastal zone

Developing a field experiment to study the different aspects of the marine system involves both the co-operation of research groups from distinct disc iplines and the use of various meteorological and oceanographical sensors d eployed simultaneously at different locations. The information obtained, st ored in voluminous data sets and frequently in various formats, needs to be visualized and analysed in different ways to provide knowledge of the dyna mics of the system examined. There is therefore need for tools to be able t o: (i) access and retrieve data sets stored in various file formats, and (i i) to allow their visualization and analysis. In this work, a user-friendly visualization and analytical tool was developed for this purpose using the IDL (Interactive Data Language v.5.3). It allows the description, interpre tation and analysis of the temporal and spatial variability of both scalar and vector variables. A description of the software is given and an applica tion using data from the High Frequency Flux (HFF) experiment, part of the European MTP II-Mater research project, in the Gulf of Lions is presented.
