Louis Druehl & Bridgette Clarkston 
Pacific Seaweeds 
Updated and Expanded Edition

This updated and expanded guide thoroughly documents every aspect of seaweed life, from species identification and seaweed biology to the essential—and often surprising—roles seaweed plays in the marine ecosystem and our everyday lives. Seaweeds are used in everything from cosmetics to sustainable biofuels, and some species, like kelp, contribute to the remediation of coastal ecosystems.


Featuring an attractive new full-color design, the expanded
Pacific Seaweeds includes updated species descriptions, dozens of additional color photos, new species discovered since the original edition, and brand-new sections on common shore plants and the use of DNA techniques to discover, catalog and identify seaweeds. It also features several new recipes and an essay on umami—because in addition to all its other uses, some species of seaweed make delectable food.


Packed with illustrations, vivid color photographs, comprehensive scientific information and further readings, this easy-to-use guidebook will appeal to marine biologists, amateur beachcombers, gourmet foragers and everyone in between.
