5. ACKNOWLEDGEMENTS
We thank all our friends, colleagues and divers who contacted us to provide information about sea urchin mortality events. We also thank the incredible technicians from Puertos del Estado-Ministerio de Fomento who collected and efficiently organized the Spanish coast buoy data and make them free accessible to everyone. We acknowledge the use of imagery from the NASA Worldview application (https://worldview.earthdata.nasa.gov/) operated by the NASA/Goddard Space Flight Center Earth Observing Science Data and Information System (EOSDIS) project, although we did not include these images in the paper, these were very useful to stablish the chronology of the storms over the Atlantic archipelagos.
