The World Ocean Assessment – or, to give its full title, The First Global Integrated Marine Assessment – is the outcome of the first cycle of the United Nations' Regular Process for Global Reporting and Assessment of the State of the Marine Environment, including Socioeconomic Aspects. The Assessment provides vital, scientifically-grounded bases for the consideration of ocean issues, including climate change, by governments, intergovernmental agencies, non-governmental agencies and all other stakeholders and policymakers involved in ocean affairs. Together with future assessments and related initiatives, it will support the implementation of the recently adopted 2030 Agenda for Sustainable Development, particularly its ocean-related goals. Moreover, it will also form an important reference text for marine science courses.
Please note that the publisher has cancelled plans for a paperback version.

"Hundreds of scientists from many countries [...] indicate that the oceans' carrying capacity is near or at its limit. It is clear that urgent action on a global scale is needed to protect the world's oceans."
– Ban Ki-moon, Secretary-General of the United Nations, from the Foreword
"Our oceans are an essential component to supporting life on Earth, yet their health is being hit from all sides. The First Global Integrated Marine Assessment helps us grasp the current situation and compels us to do our part in protecting this vital resource. Urgent action is needed, and this Assessment provides policy-makers with an important scientific baseline upon which to act. The report is also a great resource for students, scientists, the general public and anyone with an interest in learning more about the oceans, and what we can do – and need to do – to protect them."
– Erik Solheim, Head of UN Environment
"Throughout The First Global Integrated Marine Assessment experts state that ocean ecosystems are unable to cope with the impact of multiple anthropogenic stressors. As a consequence, the life-supporting services that the ocean provides to humankind are in imminent danger. Due to the complexity of ocean processes, solutions should be sought and verified based on the most advanced ocean science and observations. Making them applicable globally and for all requires intensive capacity development and marine technology transfer."
– Vladimir Ryabinin, Executive Secretary of IOC/UNESCO
"The First Global Integrated Marine Assessment has arrived at a critical time. Never before has it been possible to acquire the depth and breadth of information gathered in this masterful compilation. Never again will there be a better time to apply the knowledge presented here to develop policies that will enable humankind to make peace with the natural ocean systems that underpin everything we care about, including our own existence."
– Sylvia Earle, Explorer in Residence at National Geographic, Founder of Mission Blue, and Founder of Deep Ocean Exploration and Research (DOER)
