Evidencias de desacople físico-biológico en el sistema de surgencia en La Guajira, Caribe colombiano

the horizontal and vertical distribution of temperature, salinity, magnitude of winds and chl-a concentration were described, during the upwelling season in the guajira, colombian caribbean, through hydrographic in situ and satellite information, showing variability in spatial distribution of chl-a during the season with the maximum trade winds in the region. in both, the winds were mainly n to ne and favorable to coastal upwelling, although with a higher intensity during february of 2006. the changes in sea surface temperature and salinity allowed for the determination of the existence of three main upwelling nuclei: the coastal area between the cabo de la vela and punta gallinas (cv-pg), the zone between puerto bolivar and the cabo de la vela (pb-cv) and the zone between santa marta and the parque nacional natural tayrona (sm-pnnt). at the end of the upwelling season (february 2006), greater winds increase the offshore advection and the depth of the mixed layer, generating a mismatch between the upwelling and the planktonic biomass in the region.
