From early Febrruary to mid March 2020, PhD student Esperanza Broullón visited the Scripps Institution of Oceanography at the University of California San Diego. In collaboration with Peter J.S. Franks, and in the framework of the REMEDIOS project, they analyzed the field data collected during the field cruise carried out in summer 2018. They got surprising results about the evolution of the chlorophyl maximum and the formation of thin layers. Well done Espe!
