How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The upwelling cores on the Caribbean Colombian coasts are mainly located at the Peninsula de la Guajira and Cabo de la Aguja. We used monthly averaged Moderate Resolution Imaging Spectroradiometer (MODIS) sea surface temperature as the only information to build up a prediction model for the upwelling events. This comprised two steps: (i) the reduct...

The relationship between SST and chlorophyll fields from satellite imagery can be computed from several methods. However, the value of the correlation of both fields uses to be lower than expected. It is demonstrated that this is due to a shift between the two fields from the time response of the biological system and the marine dynamic. Authors pr...
Article
Lake Maracaibo, an important wet coastal area located in the Caribbean Sea, is connected to the Gulf of Venezuela by a narrow, shallow channel known as Barra de Maracaibo. The water quality of this is poor owing to the very low water rate exchange with the Gulf. The authors make use of sea surface temperature (SST) satellite imagery and numerical m...
Article
The development of the mathematical morphology meant a major turn on digital image processing. Among its operators, the skeleton is one of the most difficult to apply. Authors have studied the sensitivity of the fractal dimension of the skeleton of geometrical structures in a digital image when its spatial resolution and threshold level change. The...

The upwelling at Punta Gallinas in the Guajira Peninsula (Colombian Caribbean) was studied from the point of view of the Mathematical Morphology using 10 years of monthly composite MODIS-SST imagery. Among all the morphological operators, the skeleton is widely used to compute the axis of the of the SST fields for the observed upwelling events. The...
