New edition of the Global Ocean Health OA report

Global Ocean Health, a program of the National Fisheries Conservation Center, just released a new edition of their “Ocean Acidification Report”.

In this issue you will hear about Bob Foy’s research on king crabs, coccolithophores, sexier male fleas, the OA Alliance, and more.

Update to SDG14.3 Voluntary Committment: Enhancing global ocean acidification monitoring and research by GOA-ON

Update from 25 January 2018: GOA-ON contributes to the Sustainable Development Goals and the 2030 Agenda

The 2030 Agenda for Sustainable Development, adopted in September 2015 by the United Nations, contains 17 Sustainable Development Goals (SDGs). Goal 14, life below water, is to conserve and sustainably use the oceans, seas, and marine resources, and consists of 10 targets. Of particular interest to the Global Ocean Acidification Observing Network (GOA-ON) community is target 14.3, minimize and address the impacts of ocean acidification, including through scientific cooperation at all levels.

GOA-ON directly contributes to the achievement of SDG 14.3. At the June 2017 UN Oceans Conference, which focused on SDG 14, GOA-ON made a voluntary commitment to expand the spatial and temporal coverage of ocean acidification observations around the world, and participated in multiple side events as well as the Partnership Dialogue on ocean acidification. In addition, GOA-ON has joined forces with several partner organizations to conduct capacity building workshops around the world, which consist of lectures, practical training, and, in some cases, the provision of sensing equipment to local scientists.

New edition of the “OA-ICC Highlights”, October – December 2017


The new edition of the “OA-ICC Highlights” summarizes the project’s main activities and achievements over the period October – December 2017. We have adopted a new format which allows us to provide a bit more information on the various activities. The content is structured around the  three major areas of work of the OA-ICC: science, capacity building and communication. Links to the project’s main resources are also provided.

Ocean acidification and carbon dioxide uptake in the global ocean

The ocean acts as a large sink for anthropogenic carbon dioxide (CO2), and the continuous oceanic uptake of CO2 has changed the chemical properties of the seawater. Increasing ocean acidification is a particular concern because it reduces the ocean’s capacity for CO2 uptake, which accelerates global atmospheric warming and affects marine ecosystems by disturbing plankton growth. The Japan Meteorological Agency (JMA) has reconstructed surface ocean carbonate system parameters including monthly sea surface pH and oceanic CO2 sink after 1990 based on a global oceanographic observation database, SOCAT V5 (Bakker et al, 2016) and GLODAPv2 (Olsen et al, 2016). The results reveal a clear trend of pH decrease in the global ocean, and decadal variability in CO2 sink of weakening in 1990s and strengthening after 2000 (Figs. 2 and 3). The gridded datasets and graphical maps (2dimensional and sphere mapping) of reconstructed values of surface ocean carbonate system parameters and sea-air CO2 flux are distributed via JMA website.

Emerging understanding of seagrass and kelp as an ocean acidification management tool in California

This report communicates emerging scientific understanding of the ability of seagrass and kelp to ameliorate ocean acidification (OA) in a California-specific context. It provides guidance on next steps for the State as it considers future nature-based actions to reduce the negative impacts of OA in California and beyond.

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.
