If you’ve dreamt of seeing the ocean depths but are too frightened to dive,
Robert Kunzig’s Mapping the Deep, now in paperback, makes a good substitute for
the real thing. He describes the landscape of the deep: metre-long worms waving
around hot volcanic vents in the ocean floor, and wing-footed snails that weave
mucus webs. Kunzig’s aim is to show how oceanographers made these discoveries
and to share them with us. It is admirably achieved. Published by Sort of Book,
£8.99, ISBN 0953522717.
