Variability of sea surface temperature (SST) in the northern Benguela was s
tudied using a time-series of mean weekly SST images from 1981 to 1990. Mea
n SST, standard deviation (SD) and coefficient of variation (CV) maps were
generated to investigate general temporal trends; charts of mean spatial SD
and CV were constructed to examine general spatial trends; latitude-specif
ic time-series were assembled for tracking the system's behaviour; and leve
ls of cloud cover were assessed. The results give a detailed representation
of the region's surface variability during the 1980s and provide new insig
hts into interannual variability. The relevance of satellite image time-ser
ies and these results to fisheries research is briefly discussed.
