A comparison of primary production models in an Antarctic mesoscale area
XVII Simposio Ibérico de Estudios de Biología Marina In the last decades remote sensing models to estimate ocean primary production (PP) have been developed in order to monitor large areas of the global ocean (i.e. Eppley et al ., 1985; Behrenfeld and Falkowsky 1997; Marra et al ., 2003; Behrenfeld...
