In Beneath Cold Seas, David Hall takes us into the underwater world of the Pacific ocean, home of the most diverse and visually spectacular marine life of any temperate or cold-water ecosystem on the planet. From tiny, candy-striped shrimp to giant Pacific octopus, alabaster nudibranches to rockfish schooling among kelp, and orchid sea stars to white-sided dolphins, Hall’s stunning photographs reveal both the symbiotic and predatory relationships that can be found in these waters. State-of the-art camera equipment and special lighting allow Hall to capture this underwater world in ways that will surprise even those most familiar with it and amaze the rest of us. Sarika Cullis-Suzuki discusses the conservation issues facing this rich yet vulnerable ecosystem.
