El Hierro volcano helps to improve algorithms used by satellites
Information provided by satellites on the amount of chlorophyll-A and the roughness of the sea following the eruption of the underwater volcano off the island of El Hierro (Spain) did not coincide with the actual data collected in situ by vessels carrying out oceanographic studies. The models have been corrected by researchers at the University of Las Palmas de Gran Canaria, who have for the first time processed very high resolution images of this kind of natural phenomenon captured from space.Image taken by the satellite WorldView-2 in October 2011. The bright green waters indicate high concentrations of volcanic material flowing from the brown zone, which is where the volcano is located. On the right, the ‘diffuse attenuation coefficient’ has been applied &ndas… Read more »
