    Seasonal and inter-annual variability of SST and chlorophyll-a off Angola
    (2006) Filipe, Vianda Lulendo Luankosi; Shillington, Frank; Agenbag, Jacobus
    The aim of this dissertation is to use satellite-derived images for the study of spatial and temporal variations in SST and in concentration of surface chlorophyll-a of the main oceanographic features off Angola. SST time-series over the 1987 to 2002 were derived from Meteosat 5-day SST composites with a spatial resolution of about 5-6 km in Angolan waters and a thermal resolution of 0.5°C. Chlorophyll-a data were from a 5-day composite of SeaWiFS GAC (4.5 km 'Global Area Coverage') images. Such images were available on a format comparable with the Meteosat SST composite images and covered the period 1998 to 2004.
