Partnering for a sustainable ocean – the role of regional ocean governance in implementing Sustainable Development Goal 14

In this report, two sets of case studies provide a detailed exploration of the contribution that regional approaches to ocean sustainability can make. Selected to highlight a variety of regions and a range of ROG types, eight of the case studies pertain to particular SDG14 targets, and five highlight the role that regional approaches can play in advancing integrated ocean governance overall. The case studies show that regional organisations have mandates covering most of the SDG14 targets and that they are already addressing a range of key issues, including marine pollution, sustainable management and production, fisheries, and conservation. At the same time, cross-cutting initiatives are starting to bring a new level of cooperation and coherence to a notoriously fragmented ocean governance system.

Oceans of impact: challenges to actions

The ocean covers nearly three quarters of the Earth’s surface, contains 96% of its living space, harbours enormous biological and genetic diversity, provides around half of the oxygen in the atmosphere and is an increasingly important source of protein for a rapidly growing world population. However, human activity is having an impact on this precious resource on local, regional and global scales.

The ocean has been experiencing substantial changes in marine physics, chemistry and biology including ocean acidification, rising seawater temperature, ocean deoxygenation and sea level rise. These four, often interacting factors, are expected to increase over the coming decades depending on the concentration of greenhouse gases in the atmosphere.

It is imperative that international decision-makers and stakeholders understand the enormous role the ocean plays in sustaining life on Earth, and the consequences of a high CO2 world for the ocean and society.

New Zealand’s environmental reporting series: environmental indicators – ocean acidification

Our oceans have become more acidic by absorbing and storing the high levels of atmospheric carbon dioxide (CO2) emitted mainly from human activities. Ocean acidification is projected to continue for generations if substantial emissions of CO2 from human activities continue.

Ocean acidification may cause widespread harm to our marine ecosystems. More acidic waters make shell-building harder for species with carbonate shells, affecting their survival, growth, and reproduction. These organisms include plankton, which form the base of the marine food chain, and other species harvested for customary, commercial, or recreational purposes. Ocean acidity also affects the behaviour and physiology of some fish and invertebrates.

New edition of the “OA-ICC Highlights”, July – September 2017

The new edition of the “OA-ICC Highlights” summarizes the project’s main activities and achievements over the period July – September 2017. The information is structured around the OA-ICC three major areas of work: science, capacity building and communication. Links to the project’s main resources and an explanatory video on their use are also provided.

Dem Ozeanwandel auf der Spur BIOACID – Biologische Auswirkungen von Ozeanversauerung (in German)

Als „das andere Kohlendioxid-Problem“, als „böser kleiner Bruder der Erwärmung“ und, zusammen mit Temperaturanstieg und Sauerstoffverlust, als Teileines „tödlichen Trios“ ist die Ozeanversauerung bekannt geworden – eine chemische Veränderung, die ausgelöst wird, wenn sich Kohlendioxid (CO2) aus der Atmosphäre im Meerwasser löst. Einerseits bremst die CO2-Aufnahme den globalen Klimawandel. Andererseits beeinflusst sie das Leben und die Stoffkreisläufe im Ozean – mit Folgen für alle, die von ihm abhängen.

Der deutsche Forschungsverbund BIOACID – Biological Impacts of Ocean Acidification (Biologische Auswirkungen von Ozeanversauerung) untersuchte von 2009 bis 2017, wie marine Lebensgemeinschaften auf Ozeanversauerung reagieren und welche Konsequenzen dies für das Nahrungs – netz und die Stoff- und Energieumsätze im Meer sowie schließlich auch für die Wirtschaft und Gesellschaft hat. An dem Projekt, das am GEOMAR Helmholtz-Zentrum für Ozean forschung Kiel koordiniert wurde, beteiligten sich mehr als 250 Forschende verschiedener meereswissen – schaftlicher Disziplinen aus 20 deutschen Instituten. Mit rund 580 fachlich begutachteten Publikationen trug BIOACID maßgeblich zum internationalen wissenschaftlichen Diskurs bei. Das Bundesministerium für Bildung und Forschung unter stützte das Projekt über drei Förderphasen mit insgesamt 22 Millionen Euro.

Exploring ocean change: BIOACID – Biological Impacts of Ocean Acidification

“The other carbon dioxide problem”, “the evil twin of global warming”, or part of a “deadly trio”, together with increasing temperatures and loss of oxygen: Many names have been coined to describe the problem of ocean acidification – a change in the ocean chemistry that occurs when carbon dioxide (CO2) from the atmosphere dissolves in seawater. On the one hand, the ocean’s CO2 uptake slows down global climate change. On the other, this absorption affects the life and material cycles of the ocean – and all those who depend on it.

Between 2009 and 2017, the German research network BIOACID (Biological Impacts of Ocean Acidification) investigated how different marine species respond to ocean acidification, how these reactions impact the food web as
well as material cycles and energy turnover in the ocean, and what consequences these changes have for economy and society.

9 basic pHactoids about ocean acidification

The ocean is the beating, swirling heart of Earth’s climate system. Just as the heart circulates blood and regulates body temperature, the ocean regulates the global climate system by controlling the circulation of heat and moisture. And just as our own hearts, it is fragile and prone to contamination.

In late September, the Bay Area Climate Literacy Impact Collaborative (BayCLIC), with the support of the Institute at the Golden Gate, held the first Local Climate Science & Education workshop. More than 80 attendees representing formal teachers, informal educators, and scientists gathered for the workshop, Deep Dive into Ocean Acidification. The event spanned subject matters like how scientists are studying local impacts of ocean acidification, how educators are bringing this science into their educational settings, and how we can include solutions in our climate messaging.
