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 ocean is changing faster than it has in the last 66 million years. Now, Oregon oysters are being farmed in Hawaii. That fix won’t work forever.
A little more than ten years ago, a mysterious epidemic wiped out baby oyster populations. After two years of massive losses and no answers, scientists testing the waters discovered what was really wrong: the ocean water flowing into the hatcheries had changed, and the oysters weren’t able to build their shells.

The NOAA/NOS/National Centers for Coastal Ocean Science (NCCOS) and the NOAA/OAR/Ocean Acidification Program (OAP) are soliciting proposals for the Identification and Application of Acidification Thresholds in Coastal Ecosystems. The goal is to develop a threshold detection and warning capability for ocean acidification in concert with other stresses. This includes identification of indicator species and parameters (ecological, economic, and/or social) to monitor that might provide early warning of impending change from one ecosystem state to another. Funding is contingent upon the availability of Fiscal Year 2018 Federal appropriations. It is anticipated that projects funded under this announcement will have a September 1, 2018 start date. Applicants should submit proposals not to exceed $350,000 per year for projects generally 2-4 years in duration, with a total multi-year budget not to exceed $1,050,000. Funding for this program is contingent upon the availability of funds, which may not have been appropriated at the time of this announcement.
Due Date: Letters of Intent must be received by 5:00 p.m. Eastern Time on December 8, 2017 and are required before submitting a full proposal. Full applications must be received and validated by Grant.gov by 11:59 p.m. Eastern Time on February 13, 2018.
The full funding opportunity and information on how to apply can be found on grants.gov.
For more information, please contact Beth Turner, NOAA/NCCOS, 603-862-4680 or firstname.lastname@example.org.

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.
