Abstract
This paper demonstrates the important contribution that remote sensing can make to coastal zone monitoring. Coastal processes operate across spatial scales ranging from local to regional, and with temporal scales ranging from diurnal to long term. Extensive use of sensor data fusion and multi-resolution analysis are essential to derive the full benefit from available data sources and to characterise fully the properties of the observed scene.
For coastal applications, remote sensing has primarily been used in a qualitative or descriptive way. The particular focus for this study is on approaches to quantitative modelling as instrument capabilities move towards the operational use of data, with particular emphasis on ESA ERS missions.
Five potential case studies have been analyzed in depth, and for each case, the potential data sources and modelling approaches have been prioritized.
The study areas are the North Sea and Mediterranean coastal areas (North Ionian Sea) that are both of strategic economic and environmental importance to Europe.
The case studies analyzed cover the most important applications for coastal zone monitoring lincluding the evolution of sea bed topography, the current variability in coastal waters due to density gradients, the sea temperature variation with particular regard to discrimination between anthropogenic and natural effects on temperature distribution, the identification of areas subject to eutrophication that could be related to overheated and polluted water diffusion, and monitoring of oil spills and the diffusion of oil films.
The most suitable data and models for each case have been selected.
The study is being performed under ESA/ESTEC contract number 11972/96/NL/CN.
