NOAA's Ocean Acidification Program supports research that focuses on economically and ecologically important marine species. Research of survival, growth, and physiology of marine organisms can be used to explore how aquaculture, wild fisheries, and food webs may change as ocean chemistry changes.
A number of NOAA National Marine Fisheries Service Science Centers have state-of-the-art experimental facilities to study the response of marine organisms to the chemistry conditions expected with ocean acidification.
The Northeast Fisheries Science Center has facilities at its Sandy Hook, NJ and Milford, CT laboratories; the Alaska Fisheries Science Centers at its Newport, OR and Kodiak, AK laboratories; and the Northwest Fisheries Science Center at its Mukilteo and Manchester, WA laboratories. All facilities can tightly control carbon dioxide and temperature. The Northwest Fisheries Science Center can also control oxygen, and can create variable treatment conditions for carbon dioxide, temperature, and oxygen. These facilities include equipment for seawater carbon chemistry analysis, and all use standard operating procedures for analyzing carbonate chemistry to identify the treatment conditions used in experiments.
Both deep sea and shallow reef-building corals have calcium carbonate skeletons. As our oceans become more acidic, carbonate ions, which are an important part of calcium carbonate structures, such as these coral skeletons, become relatively less abundant. Decreases in seawater carbonate ion concentration can make building and maintaining calcium carbonate structures difficult for calcifying marine organisms such as coral.
Increased levels of carbon dioxide in our ocean can have a wide variety of impacts on fish, including altering behavior, otolith (a fish's ear bone) formation, and young fish's growth. Find out more about what scientists are learning about ocean acidification impacts on fish like rockfish, scup, summer flounder, and walleye pollock.
Shellfish, such as oyster, clams, crabs and scallop, provide food for marine life and for people, too. Shellfish make their shells or carapaces from calcium carbonate, which contains carbonate ion as a building block. The decreases in seawater carbonate ion concentration expected with ocean acidification can make building and maintaining calcium carbonate structures difficult for calcifying marine organisms like shellfish. This may impact their survival, growth, and physiology, and, thus, the food webs and economies that depend on them.
Plankton are tiny plants and animals that many marine organisms, ranging from salmon to whales, rely on for nutrition. Some plankton have calcium carbonate structures, which are built from carbonate ions. Carbonate ions become relatively less abundant as the oceans become more acidic. Decreases in seawater carbonate ions can make building and maintaining shells and other calcium carbonate structures difficult for calcifying marine organisms such as plankton. Changes to the survival, growth, and physiology of plankton can have impacts throughout the food web.
The Environmental Assessment Program (EAP) program within the Department of Ecology is looking to fill a Marine Scientist (Natural Resource Scientist 2) position. Applications are due April 24, 2018.
This position is located at our Headquarters Building in Lacey, WA but conducts work statewide. This position is responsible for conducting marine water quality monitoring, with a focus on ocean acidification. Responsibilities include implementing the addition of ocean acidification-relevant parameters to Ecology's marine waters monitoring program in Puget Sound. This position is also responsible for oceanographic sampling gear preparation and use, instrument calibration (CTD and other electronic sensors), laboratory sample analyses, data analysis, and report writing. The data collected is used to determine the status and trends of marine water quality in context to ocean acidification in Washington state.

The Olympic Coast, located in the Pacific Northwest U.S., stands as a region already experiencing effects of ocean acidification (OA). This poses risks to marine resources important to the public, especially local Native American tribes who are rooted in this place and depend on marine treaty-protected resources. This project brings together original social science research, synthesis of existing chemical and biological data from open ocean to intertidal areas, and model projections, to assess current and projected Olympic Coast vulnerabilities associated with OA. This critical research aims to increase the tribes’ ability to prepare for and respond to OA through respective community-driven strategies. By constructing a comprehensive, place-based approach to assess OA vulnerability, decision-makers in the Pacific Northwest will be better able to anticipate, evaluate and manage societal risks and impacts of OA. This collaborative project is developed in partnership with tribal co-investigators and regional resource managers from start to finish and is rooted in a focus on local priorities for social, cultural, and ecological health and adaptive capacity.
The Washington state governor’s appointed board, the Marine Resources Advisory Council, released its first update in five years to the state’s coordinated response to ocean acidification. In the five years since the Blue Ribbon Panel’s report, there have been significant scientific advances and progress made on the 42 recommended actions. The report highlights the new research that justifies more concerted efforts to combat ocean acidification. The report is publicly available here.
Eleven NOAA and Washington Sea Grant scientists from the National Ocean Service, National Marine Fisheries Service and the Office of Oceanic and Atmospheric Research served on the Blue Ribbon “Refresh” Panel and contributed to the report.

The North Pacific Research Board (NPRB) announces the release of its Core Program Request for Proposals (RFP). The 2018 RFP has an anticipated funding amount of $4.45 million. The North Pacific Research Board specifically lists ocean acidification as a topic of interest for proposed projects.
