This symposium will have plenary speakers set the stage of the science, economic impacts, and management responses of ocean acidification in estuaries. The plenary will be followed up by special sessions that will include both invited and contributed talks. The symposium will also include a workshop led by the Alliance of Coastal Technologies on making acidification measurements, and on sensor technologies. This symposium will offer new insights relating to ocean acidification as the focus is on acidification in estuaries and in other freshwater-influenced waters, rather than on the open sea. Moreover, it will highlight an increasingly recognized topic, and one that is of increasing urgency, as witnessed by the attention given to the Washington State Governor who established a Blue Ribbon Panel on Ocean Acidification in Washington’s coastal and inland waters.

He is in direct contacts with various stakeholders, both at local and global level. He is a member of the Advisory Board of the Ocean Acidification International Coordination Centre (OAICC) and hired as expert by the Swedish Agency for Marine and Water Management. He is also in contact with economists through his role as theme leader in a working group on economics of ocean acidification that brings together scientists from many international scientific initiatives (EPOCA, BIOACID, UK-OA), economists, and representatives of major international organizations including UNESCO, FAO, OECD, World Bank, IGBP, and the CIESM. He is an active partner in several science education projects, including “Inquiry-to-Insight”, a collaboration between the University of Gothenburg and Stanford University, and the recently funded “VirtualLab project” which is a collaboration between the Faculty of Education and Faculty of Sciences at the University of Gothenburg.

Alan Barton, Production Manager, Whiskey Creek Shellfish Hatchery & Project Coordinator, Pacific Coast Shellfish Growers Association Monitoring Program

Alan Barton is the Production Manager and Research Coordinator at Whiskey Creek Shellfish Hatchery in Netarts, Oregon, a major supplier of oyster larvae to shellfish farms throughout the Pacific Northwest.  He is heavily involved in efforts to understand the effect of deteriorating water chemistry on production at the hatchery, and recently collaborated with Oregon State University (OSU) researchers to publish the first evidence linking ocean acidification to mortality of oyster larvae in naturally occurring seawater.  Alan also serves as the Project Coordinator for the Pacific Coast Shellfish Growers Association (PCSGA) Monitoring Program, a collaborative effort established between shellfish growers and members of the research community, with the expressed goal of accurately monitoring seawater quality in areas of commercial shellfish production. Alan’s educational background includes an undergraduate degree in Industrial Engineering from the Georgia Institute of Technology, and a Master’s Degree in Marine Science from the University of Georgia.  He has worked extensively over the past decade in support of the shellfish industry, as an employee of OSU’s oyster breeding program, the Molluscan Broodstock Program, from 2004-2008, and in his current capacity as an employee at Whiskey Creek.

Jay Manning, Partner, Cascadia Law Group

Jay Manning rejoined Cascadia Law Group in 2011 after more than six years as the Director of the Washington Department of Ecology and Chief of Staff to Washington State Governor Christine Gregoire. His law practice focuses on environmental and energy matters, providing consulting and legal services to clients involved in significant issues of public policy, major projects seeking government approval and/or funding, and on difficult management challenges. As Chief of Staff from 2009 to July of 2011, Jay worked closely with the Governor and her Cabinet and Senior Staff to address budgetary and public policy challenges facing state government.  As Director at Ecology from 2005 to 2009, Jay’s primary areas of focus were managing the state’s water resources, including implementing the new Columbia River Water Program and guiding the effort to bring the Puget Sound back to good health by 2020.  Jay co-chaired the Washington State Blue Ribbon Panel on Ocean Acidification in 2012, which led to an Executive Order directing the state’s implementation of the panel’s recommendations for a coordinated, regional response.

Special Sessions

SCI-014 Drivers and Consequences of Near-shore Ocean Acidification
Convened by: George Waldbusser (, Denise Breitburg, Lisa Levin and Gretchen Hoffmann

The focus of this session will be on examining different drivers and patterns of ocean acidification in near-shore environments and the possible consequences to different levels of biological organization. Within these near-shore habitats drivers such as upwelling/overturn, eutrophication, and watershed alteration will interact with increasing atmospheric carbon dioxide in complex ways with possibly complex outcomes for biological responses. Submissions are encouraged that utilize case studies of different systems or address links between temporal variability in near-shore carbonate chemistry and biological responses. 

SCI-015 Acidification and Hypoxia in Estuaries
Convened by: Tawnya Peterson (, Joseph Needoba, Curtis Roegner and Catherine Corbett

Acidification and hypoxia, often in combination, are increasingly threatening the health of aquatic ecosystems worldwide. Estuaries, which receive inputs from freshwater and marine systems, are particularly vulnerable to the presence of multiple stressors. Understanding and predicting how estuarine ecosystems respond to acidification or hypoxia involves identifying and characterizing processes that mitigate or exacerbate these conditions, including the phenology of algal blooms and variations in water chemistry (e.g. dissolved inorganic carbon and alkalinity) associated with oceanic versus river inputs to estuarine waters. In this session, we seek contributions that focus on the relative roles of marine and freshwater processes and their interactions in driving or mitigating estuarine acidification or hypoxia. Regional contrasts and comparisons between different estuary types are welcome. We are particularly interested in studies that link key processes to estuarine ecosystem structure or biogeochemical function through observations or models and that include a management perspective. 

SCI-019 Extending Acidification Modeling from the Ocean to Estuaries
Convened by: Samantha Siedlecki (

In the open ocean, decades of monitoring have culminated it the development of numerous ocean models that can predict changes in ocean chemistry and related ecosystem changes due to rising atmospheric CO2. However, extending these models to the near-shore and estuarine environments is complicated by numerous stressors that can exacerbate the effects of ocean acidification in coastal waters (e.g., freshwater input, tidal forcing and stratified waters, nutrient over-enrichment and eutrophication, hypoxia), all of which must be incorporated into coastal models. This session will explore ways that acidification modeling can be extended to near shore environments and obstacles to developing causal and predictive models at a variety of spatial and temporal scales.

SCI-020 Acidification Observing Networks and Data Sharing
Convened by: Andrew Dickson (  and Emilio Mayorga (

Observational data and data products on ocean acidification and its implications on ecosystem health are needed to inform policy and the public. Ocean acidification is occurring at a global scale but can be exacerbated by local processes; therefore local measurements and observations must be linked to larger regional and global data sets in order to accurately understand ocean acidification and its drivers and predict future ecosystem changes. This requires collection of data at local to global scales as well as integration of data into a shared data management platform. The observing data can then be input into models (see session SCI-019) and other data visualization tools (this session) to understand the drivers and effects of changing ocean conditions at a variety of spatial and temporal scales. Observing data are critical tools that can be utilized by industry, policy makers, and regional managers to develop strategies to mitigate the effects of ocean acidification and develop strategies to adapt to expected changes whenever possible. This session will examine ocean acidification observing networks, existing data sharing platforms and visualization tools and strategies, and explore development of larger-scale observing networks.
