Aris, an ocean enthusiast, and Damar, her tech-savvy friend, join Dr. Eshe's Undersea Kelp Voyagers expedition to explore towering kelp forests beneath cold Pacific waves. Together they measure holdfasts, tag sea urchins and sea stars, and experiment to remove invasive slugs threatening the ecosystem. Through underwater tablets, bioluminescent nights, and stormy challenges, they learn how restoration science can heal underwater rainforests. Floating nurseries, lab experiments, and a coastal festival demonstrate kelp's power to nurture life above and below the surface. Perfect for young readers ages 5–10, this fun, comical adventure immerses kids in marine botany, biodiversity, and the joy of discovery.
