How much, or rather how little, is known about the biology of the Mediterranean Deep Sea ? Find the answer in this 126-page CIESM volume, which is rich in illustrations and contains hundreds of bibliographic references. The Monograph summarizes the extent of our knowledge -- often surprisingly scant -- for each major taxonomic group and for key biological processes. It also surveys the rich diversity of deep-sea ecosystems -- from canyons, brine lakes, cold seeps, deep-sea mounts, continental slopes to abyssal plains -- encountered in the Mediterranean and likely to promote a complexity of life which is yet to be explored. The volume also identifies major paths of research on biodiversity and processes and explains why the Mediterranean Sea offers outstanding, unique opportunities to explore the deep sea.
