| Sumario: | Punta Lavapié, located in the VIII region of Bio-Bio, is a very important coastal upwelling area which presents high and low activity phases during the year. Through remote sensing technology, a spatial and temporal characterization was generated for Punta Lavapié upwelling system, which has, indeed, economic significance due to big fishing volumes in a normal year. A long-term time series of three years (from December 1998 until December 2001) of SST NOAA/AVHRR images was processed for Punta Lavapié. Some SST images with clouds were reconstructed through a digital image interpolator developed by CEE, which allowed to have more images into the time series. Seasonal average images and advective vector fields through the MCC objective method were obtained to summarize the results |
