Nutrient concentration determination in the post-eruptive process of the volcano of El Hierro

Abstract

This study shows the behavior of nutrients in the water column in the submarine volcanic area south of the island of El Hierro 3 years after its eruption. For this, silicates, nitrates and phosphates were analyzed and oxygen, fluorescence and pH were measured with sensors to help explain and identify the eruptive phenomenon and their effect on the distribution of nutrients. With this information it will be concluded if the pre-eruptive conditions of nutrients have been recovered or how are these important compounds seem to be reacting to the remaining volcanic activity.
