Despite gaps in our knowledge, the biogeography of several key deep-sea environments has also been reviewed: hydrothermal vents (Tunnicliffe et al 1996, 1998, van Dover et al 2001, 2002), cold seeps (Sibuet and Olu 1998, van Dover et al 2002), trenches and the abyssal plain (Ekman, 1967, Gebruk et al 1997, Vinogradova 1997).
