Of the first edition:'I have had the pleasure of reviewing a large number of the "Introducing" guides from Dunedin Academic Press... The format is always the same - authorative but easy to understand text, interspersed by bold, full colour diagrams and photographs. The planet is two-thirds covered by oceans and seas and the energy they contain massively affects the way the Earth system (especially climate) works.The nice thing about these guides is that the bite-sized nature of each chapter means you can dip in and out when you want to explore a particular subject, or you can sit down and read them in their entirety in only a few hours and feel that you really have learnt something by the time you have finished. For example, there is information on the chemistry, biology, the tides, waves, and so on in the one of oceanography. And, as always, the authors of both guides are experts in their fields.'Deposits magazine'I would thoroughly recommend this book to any aspiring oceanographer or serious amateur. This is a very wide and complex subject that has been covered very well indeed and very attractively in such a short volume.' International Journal of the Society for Underwater Technology
