Abstract:CZCS and AVHRR images have been used to study the spatial, temporal and spectral development of coccolithophore blooms in the NE Atlantic. It is suggested that variations in colour and reflectance in the images are due to differences in the relative concentrations of coccolithophore cells and detached plates. Also the formation and disappearance of an intense bloom in the English Channel is related to changes in water-column stability during the spring-neap tidal cycle.
