Both research groups have been recognised as a "High Performance Group" in the UAH, given their high scientific production.

The Institut de Ciències del Mar (ICM) in Barcelona is the largest marine research centre of the Spanish National Research Council (CSIC). It is made up of specialists in different aspects of oceanographic research. With the aim of understanding the ocean for the health of the planet, researchers at the ICM carry out cutting-edge research to promote the transfer of knowledge and technology in relation to ocean and climate interactions, the conservation and sustainable use of marine life and ecosystems, and the mitigation of the impacts of natural hazards and man-made activity. In 2020 the ICM was awarded the Severo Ochoa certificate of Excellence, a distinction that confirms the institution's leadership in the field of marine research in Spain and highlights its commitment to bring about social impact.
