By March the seasonal thermocline would have reappeared and the characteristic summer conditions begin to reestablish themselves initially in the southern Levantine Basin. With the initiation of the bloom, mesoscale features control the details of the re-establishment of summer conditions. Eddies can still be clearly seen as areas of higher biomass in the southern Levantine, particularly in March. Summer conditions with extremely low productivity in the surface layers, and a DCM is fully established by May and reach their peak between June and August, when all of the southern Levantine has extremely low chlorophyll levels in the surface layers. It is important to remember that the satellite only sees the phytoplankton in the uppermost layers of the system. Once the seasonal thermocline is developed, the system is characterised by a deep chlorophyll maximum. Thus the drastic changes in chlorophyll shown by these images are in reality less marked.
