We present some of the results of a geophysical and hydroacoustic exploration survey achieved in November-December 2011 in the El Hierro Island (Canarian Archipelago) aboard the RV “Sarmiento de Gamboa”. We used different geophysical techniques like multichannel seismic reflection and wide angle reflection, gravity measurements and parametric sounding, together with high resolution bathymetry mapping. The broad frequency range of the acoustic systems allows imaging the injection of buoyant volcanic plumes driven by gas bubbles exsolved from magma during the long lasting eruption of the submarine volcano.
