<P>Drawing on the expertise of marine researchers from both the natural and social sciences, this book examines how we, as both scientists and societies, can return to a sustainable co-existence with the ocean and use the tools of transdisciplinarity to bring together the diverse forms of knowledge needed to achieve this important task. </P><P></P><P>The marine sciences play a vital role in producing and providing the knowledge needed for a transition towards ocean sustainability. With a multitude of actors involved in using, exploiting, and safeguarding the seas, however, this task cannot be solved by science alone. Transdisciplinary research is needed, bringing together scientists and all other actors of society to jointly co-produce the knowledge and innovations that we so urgently need. In this context, this book examines and answers key questions at the forefront of transdisciplinary marine research: How can we provide approaches that integrate marine biodiversity and social syste
