After every 50 editions of the Ocean Newsletter, the Opinion sections are edited and compiled into the 13 following categories and published as a single volume, entitled Towards Coexistence with the Ocean: 150 Opinions.

Categories: ocean policy and legislation / security / science and technology-observations-data / technology development / coastal area management / environmental protection and conservation / biological and fish resources / resources and energy / maritime traffic and transport / area use / recreation and tourism / education / society-culture-local areas

Our purpose is to share these valuable opinions with as many people as possible in the hope that they will be of use in thinking about ocean problems.
