The evolution of the global ocean over geological periods

Yves Lagabrielle


A huge amount of work and knowledge has gone into this book, ‘The Ocean Revealed’, produced by AllEnvi, the French environmental research alliance. Cast your eye over the table of contents and you will see the wide variety of topics covered, from the ocean in paintings to deep-sea mineral resources, from the ocean’s blue colour to sea birds. This holistic approach is now essential in every discipline. For anyone dealing with the ocean, it is the only way to produce a complete and consistent result. It is no longer possible to focus on a single area of expertise. Today, two things are urgent. First, we need to help the ocean heal the wounds that human society has inflicted upon it, while we still have time. Secondly, we need to find a sustainable way of using all the ocean has to offer in terms of resources, communication and leisure. The world’s leaders are also increasingly adopting this approach to the ocean. The ocean is now more than a mere backdrop for State events. Previously, only the event mattered, the setting could be neglected. That is no longer the case. Maritime spaces have become a focus in international relations, a matter of power, might, resources and also of responsibility, development, cooperation and peace. This book shows the array of scientific disciplines that take the ocean as their subject. The role of science is vital in understanding the ocean. Apart from in the minds of a handful of regressive and obtuse politicians and leaders, the need for protection is no longer in doubt today, but conservation efforts can only be effective if we have indepth knowledge of what needs protecting: science is thus fundamental. Scientists from every discipline face a heavy burden of responsibility and they will have to broaden their view of marine and maritime issues beyond their own field to build knowledge and then put forward solutions for protection and sustainable use. It is wonderful to see that an increasing number of scientists are taking this on-board. It has a positive impact on the States’ capacities to put forward proposals during international discussions on the ocean, covering Sustainable Development Goal 14, for example, or the conservation and sustainable use of high sea biodiversity. This book is a timely resource that will inform a broad audience, not only decision-makers but anyone with a love of the ocean. Every one of us has a role to play and the people behind this book should be thanked for sharing their extensive knowledge, a valuable resource that will help us to forge our own view of the ocean while opening up new avenues for reflection.
