AbstractEstuarine environments are characterized by very complex morphodynamics and represent one of the most critical coastal regions for the exchange of sediment and nutrients. The fertilization of the continental shelf of the Gulf of Cadiz (SW Iberian Peninsula), in which the Guadalquivir and other rivers play an influential role, constitutes the major factor determining the productivity of the basin, from phytoplankton to fisheries resources as anchovy. Moreover, the input of nutrients and suspended particulate matter from the rivers has a relevant impact on several socio-economic strategic activities (aquaculture, tourism, navigation, fisheries). The work presented here was undertaken to analyze the spatial variability of the Guadalquivir turbidity plume. The incorporation of DEIMOS-1 novel satellite images of high spatial resolution (22 m) will improve our ability to map turbidity and chlorophyll in the estuary and to assess and predict the plume behavior. To achieve this goal, remote sensing images have been processed and validated against in-situ measurements from several cruises to check the quality and precision of satellite products in this coastal region. The high spatial resolution of these images will allow us to study features related to the dynamics of the turbidity plume in the river mouth and connect these patterns with the meteorological and oceanographic process controlling it.
