"la niˋa" 2007/2008 event, which covered the period of this research, did not incite any important disturbance over the typical upwelling conditions. %K upwelling %K trade winds %K nutrients %K mesotrophic %K chlorophyll a. %U http://www.scielo.org.co/scielo.php?script=sci_abstract&pid=S0122-97612010000200004&lng=en&nrm=iso&tlng=en
