CHAPTER 38
Characterization of Coastal Waters for the Monitoring of Pollution
by Means of Remote Sensing; the Use of Satellite Imagery to
Establish the Appropriate Pattern for Timing and Location of
Sampling in Coastal Waters.
J. Ojeda Zújar, E. Sanchez Rodriguez, A. Fernádez-Palacios, and J. Loder
ABSTRACT: This chapter presents a possible application of remote sensing to
establish the pattern of sampling required to monitor the condition of coastal waters.
The aim is to provide a dynamic characterization and delimitation of differing water
masses in the estuary of the rivers Tinto and Odiel (Huelva, SW Spain) under specific
synoptic conditions. This information will allow the planning of sampling routes
which guarantee spatial and temporal representativeness. The method used for the
dynamic characterization is based on a simple segmentation of one visible band.
Standard Principal Components Analysis was used to zone the estuary. The results
permit a series of recommendations as to how, when, and where to sample.
Introduction
In 1992 the Ministry for the Environment of the Junta de Andalucía (CMA), in
collaboration with the Department of Physical Geography and Regional Geographic
Analysis of the University of Seville began a line of investigation - Programme for
Monitoring the Quality and Dynamics of Coastal Zone Marine Waters using remote
sensing. The basic aims have been to:
1) evaluate the possibilities of applying remote sensing to the study of various
problems which affect the Andalucian coastal zone
