An exploration of some of the major features of Earth’s oceans, with interspersed minicomic episodes starring the author as Capt. Aquatica and a great hammerhead shark as her sidekick, Finn.
This third in the Science Superheroes series is presented by a white American researcher, marine conservationist, and National Geographic–funded “Explorer” currently living, working, and advocating for sharks in the Cook Islands in the South Pacific. Chapter by chapter, she and her co-authors describe the connected oceans that cover about three-fourths of our planet. They consider water movements and storms; examine the tidal and ocean zones and ocean floor; explain various ecosystems; introduce some sharks; survey the history of underwater exploration; and conclude with a section on environmental threats and what can be done. Text boxes introduce a dozen marine scientists, male and female, from varying times and places; several are people of color. Numerous photos and diagrams with informative captions also help break up a relatively dense text. Speech bubbles in the superhero comic sections separating the chapters are numbered so that readers can easily follow the conversation. For the most part the information is accurate though not always explained clearly. (Describing tides, the writers state that a water bulge also forms on the side of the Earth farthest from the moon “because of inertia.”) The introduction clearly distinguishes the fantasy of the comic sections from the factual exposition.
Readers able to navigate a heavy sea of information will enjoy the trip. (afterword, glossary, index, credits and image credits, resources) (Nonfiction. 11-15)
