Specific applications of satelite remote sensing to the Benguela ecosystem

The objective of this thesis was to utilise high resolution satellite data, from the NOAA AVHRR and OrbView-2 SeaWiFS sensors, to investigate the upper layer dynamics of the Benguela ecosystem in more detailed space and time scales than previously undertaken. The standard for SeaWiFS bio-optical algorithms and processing parameters are not ideal for the highly productive Benguela waters. Hence, a detailed investigation was undertaken, and the processing parameters modified for more optical application to Benguela waters. Examination of the individual radiances used in the bio-optical algorithm revealed that constituents, other than chlorophyll, were at times contributing significantly to the in-water light field. The approach adopted in this thesis was that the application of satellite data to Benguela waters should be considered either as qualitative, for event scale phenomena, or quantitative, for the longterm study.
