Colors describe areas of anomalies in simultaneous above-average sea surface chlorophyll concentration (Chl-a, SeaWiFS)
and below-average sea surface temperature distribution (SST, AVHRR). Animated image shows the spatiotemporal distribution
of persistent marine productivity along the coasts of France, Spain and Portugal in the Bay of Biscay. Graph shows the mean
monthly levels of Chl-a and SST.
