Marine algae are the supreme eco-engineers of life: they oxygenate the waters, create habitat for countless other organisms, and form the base of a food chain that keeps our planet unique in the universe as we know it. In this beautiful volume Josie Iselin explores both the artistic and the biological presence of sixteen seaweeds and kelps that live in the thin region where the Pacific Ocean converges with the North American continent-a place of incomparable richness. Each species receives a detailed description of its structure, ecological importance, and humans' scientific inquiry into it, told in scientifically illuminating yet deeply reverent and inspired prose. Throughout the writings are historical botanical illustrations and Iselin's signature, Marimekko-like portraits of each specimen that reveal their vibrant colors-whether rosy, "olivaceous," or grass-green-and whimsical shapes. Iselin posits that we can learn not only about the seaweeds but also from them: their resilience, their resourcefulness, their poetry and magic.

Artist Josie Iselin celebrates the diversity and beauty of nature with her exquisite portraits of seashells. Like her extremely popular Beach Stones and Leaves & Pods, Seashells is not a field guide but an artful and informative portrayal of a beloved part of our natural world. While it draws upon unparallelled shell collections, Seashells balances the exotic with the familiar, from tropical corals and rare fossils to everyday clamshells and barnacles. As in her previous books, Iselin arranges these precious natural objects into striking images, which she produces on a flatbed scanner. In her introduction and captions, marine geologist and paleontologist, Sandra J. Carlson introduces the reader to seashells in all their variety, explaining why they look as they do. Both an art book and a contemplation of nature, Seashells combines aesthetic delight in natural things with scientific fact and philosophical wonder.
