Story maps offer viewers a highly visual medium that incorporates text, multimedia, and (of course) maps into their narratives. Here, the GIS software giant Esri has curated a collection of approximately fifty stellar story maps related to ocean science and ocean conservation that are sure to provide interested visitors with an informative and engaging experience. As Esri explains, these story maps "were chosen for the outstanding ways that they are informing, educating, and inspiring scientists, conservationists, decision-makers, and the general public, on a wide variety of ocean issues." For a basic primer in ocean science and conservation issues, the first story map on the list (entitled "The Ocean") is an excellent starting point. From there, readers can explore whichever ocean topics strike their fancy, as this collection ranges from stunning photographic expeditions created by the International League of Conservation Photographers to explanations of oceanographic concepts and scientific research, and even history and engineering. While story maps created by Esri staff are well-represented, most of this collection features story maps that were made by government agencies, universities, and non-profit organizations from around the world.
