"Magdalena Deep Sea Fan"
Created using both MapViewer and Surfer

This image was provided by Marcel.lí Farran, Marine Geology and Physical Oceanography Dept, Instituto de Ciencias del Mar - CSIC - Barcelona, SPAIN.

This is a very nice example of turbiditic fan.  The image was created with multibeam echo-sounder data obtained in the Caribbean Sea, north of the Magdalena river mouth in Colombia. Deep ranges from -100 m. to -3990 m.

The distribution of the data is due to the short search radius used when we created the grid (300 meters) . We used this short radius in order to avoid artifacts in the map where there is no overlay between multibeam lines. The maximum distance between beams in the deepest area is around 100 meters.  Artifacts exist in the far beams due to the impossibility of filtering without a great loss of information.  This shaded map was created without smoothing the grid because we observe a loss of information for small features, such as narrow channels, when smoothing.
