Robert Kunzig’s The Restless Sea spends a lot of time, none of it
wasted, on the possible routes that led to the Earth being covered mostly by
water. It’s fascinating and painless education. The rest is about the seas being
seas of ignorance—ours that is. He covers the developments in deep-sea
exploration, adding a lament for the near-disappearance of that once teeming
fish, the cod. Most of all this is lively, sometimes vivid. This is the sea as
mystery. Published by Norton, £16.95, ISBN 0393045625.
