DOIAbstract
Marine fronts are part of the structural complexity of the sea; they are narrow boundaries separating different water masses. Fronts are caused by diverse forcing and occur throughout the world ocean at several spatial and temporal scales. Unlike terrestrial ecotones, they show high biological production, affecting pelagic and benthic organisms of all trophic levels; consequently they are important for fisheries. Solar energy stimulates biological production in the entire biosphere, but in the sea it needs to be complemented by auxiliary energy to replenish plant nutrients; a significant quantity of mechanical energy becomes available for biological production at fronts. Global change is redistributing auxiliary energy in the oceans; conseq...
