full length introduction

Think of coral reefs and you imagine warm, shallow tropical seas, not the cold, dark waters of the deep ocean. Now the deep ocean's best-kept secrets are being revealed - ancient coral ecosystems hidden from view at great depths. Lophelia.org is an information resource on the cold-water coral ecosystems of the deep ocean.
