EPA guidelines for measuring changes in seawater pH and associated carbonate chemistry in coastal environments of the eastern United States

These guidelines are written for a variety of audiences ranging from shellfish growers interested in monitoring pH with inexpensive equipment to citizen monitoring groups to advanced chemistry laboratories interested in expanding existing capabilities. The purpose is to give an overview of available sampling, analytical and data reporting approaches that will contribute to the usefulness of coastal acidification measurements for both the needs of those intending to monitor as well as those of other interested stakeholders along the Atlantic seaboard of the US. The state of the science, including recommended best practices, is rapidly evolving, so certain sections may be either too sparse or too detailed. Thus, we encourage users of the guidelines to begin with a careful review of the detailed contents listing and to take note of references to other guidelines available in the open literature.

Ocean acidification – what to measure and what to report?

The aim of SDG 14 is to “conserve and sustainably use the oceans, seas and marine resources”, and it encompasses 10 targets. The Global Ocean Acidification Observing Network (GOA-ON) is particularly involved in supporting countries to achieve Target 14.3, which aims to “minimize and address the impacts of ocean acidification, including through scientific cooperation at all levels”. GOA-ON made a voluntary commitment (#OceanAction16542) to expand the spatial and temporal coverage of ocean acidification observations around the world. To achieve this, GOA-ON participates in and organizes international meetings and world-wide capacity building workshops, which consist of practical technical training and lectures. In some cases, GOA-ON has been able to provide the necessary sensing equipment (‘GOA-ON in a box’) to scientists around the globe, supported by regional hubs of the network, e.g. the Latin American Ocean Acidification Network (LAOCA) and WESTPAC (#OceanAction15274). GOA-ON currently has 475 members from 75 countries, and is constantly growing. GOA-ON members were encouraged to explore the features of a new Ocean Acidification Information Exchange platform recently launched with the support of the US Interagency Working Group on Ocean Acidification and NOAA and operated by the Northeastern Regional Association of Coastal Ocean Observing Systems to enable discussions and facilitate communication within the OA community.

Effects of climate change on ocean acidification relevant to the Pacific Islands

Ocean acidification has the potential to significantly impact Pacific Island ecosystems and the ecosystem services they provide. There is compelling evidence that the ocean has become more acidic in response to rising atmospheric CO2 levels. As atmospheric CO2 levels continue to rise the ocean will increasingly become more acidic, and these changes are likely to persist for hundreds to thousands of years. The rate and magnitude of these changes will be directly proportional to the future carbon emission pathway followed. While a low carbon emissions pathway will clearly limit the impacts of ocean acidification, a high carbon emission pathway will lead to conditions that will threaten the long-term viability of important marine ecosystems, such as coral reefs. In the future, increased confidence in projected changes will come through a better understanding of how the large-scale changes are modulated by processes at the island scale. This will be achieved through a combination of sustained long-term measurements and higher-resolution modelling. There is also critical need to understand the impact of multiple environmental stressors, as future ocean acidification will be accompanied by ocean warming and other environmental consequences (e.g. invasive species). Finally, implementation of a viable emission pathway is urgently needed to underpin the development of sustainable adaption and resilience options, and to explore potential engineering and adaptation solutions that may be required to offset long-term ocean acidification changes.

A climate science regional action plan for the Gulf of Alaska

NOAA Fisheries recently developed a Climate Science Strategy (NCCS, Link et al. 2015; Busch et al. 2017) to meet the demand for scientific information to prepare for and respond to climate impacts on the Nation’s living marine resources and resource-dependent communities. One requirement of the NCSS is that each region shall develop a RAP that identifies actions needed to make progress in implementing seven objectives in the NCSS in each region over the next 5 years. The RAPs are also intended to increase awareness and support for these efforts, both internally and externally with partners and stakeholders. The objectives are arrayed hierarchically, and build from science infrastructure and monitoring activities (objectives 6 and 7), to process studies (objective 5), to projection of future conditions (objectives 4), and finally to management strategy evaluations (objectives 1-3) (Fig. 1).

Ocean risk and the insurance industry

A diverse array of ocean-related phenomena occur today and more are expected to emerge in the future as ocean risk evolves in response to the observed and accelerating warming, acidification, oxygen depletion and other man-made threats to the ocean. This report aims to raise awareness of potential insurance industry-related impacts of these interconnected threats and the important role the industry can play in managing emerging ocean risks, seizing new opportunities, and helping to make the industry, the global economy, and society more resilient and responsive to the consequences of a rapidly changing ocean.

Call for expert review: Intergovernmental Panel on Climate Change (IPCC) Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC)

Experts are invited to offer comments and suggestions to the author teams of the First Order Draft of the Intergovernmental Panel on Climate Change (IPCC) Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). The report authors will address every comment received when preparing the next draft in order for the review process to include the broadest possible scientific perspective. This review process will be taking place from 4 May until 29 June 2018.
