The four Ws of marine citizen science: What? Who? Why? Where?

<p>The spectrum of participation in marine citizen science (MCS) is wide. More and more enthusiasts and researchers collaborate by collecting data, analyzing information, building monitoring devices, and even designing investigations. The 4ws of MCS is a panoramic look at the diversity of participant profiles, activities that are being carried out, types of projects and ecosystems in which MCS has been contributing to the knowledge of the ocean. </p> <p>The infographic is available in three languages: English, Spanish and Catalan. </p>
