Sawtooth oscillation
WebMay 22, 2013 · We discuss a recently proposed model for the sawtooth oscillations of atmospheric carbon observed in ice age cores. The model at its simplest arises from a single reaction involving just two species, oceanic biomass and nutrient, and bears similarity to models which have been proposed to explain oscillations in glycolysis. We show that … WebJun 1, 2012 · The rapid collapse of a sawtooth oscillation which is characterized by the absence of any discernible precursor
