Biological Response

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.


FISHERIES SCIENCE CENTERS

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.

 


Corals

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.

 


Fish

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

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

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.


OAP SUPPORTED BIOLOGICAL RESPONSE PROJECTS

Mid-Atlantic Ocean Acidification Graduate Fellowship Opportunity

Ocean Acidification Program and Sea Grant

The Mid-Atlantic Sea Grant Programs in partnership with the NOAA Ocean Acidification Program, are pleased to announce the availability of Ocean Acidification Graduate Research Fellowships for a two-year period covering the 2018 and 2019 academic years. The fellowship is open to full-time graduate students at any academic institution in Delaware, Maryland, New Jersey, New York and Virginia who are engaged in coastal and marine research relevant to regional ocean, coastal, and estuarine acidification. The focus should be on improving understanding of the potential ecological consequences of increasing carbon dioxide concentration in regional coastal waters. Projects may encompass natural and/or social science research topics.

Proposals are being accepted through 5:00 pm ET on Friday, April 13, 2018 via eSeaGrant.  

This announcement and additional information can be found on each state Sea Grant program’s website.

Federal Funding Opportunity: Ocean, Coastal, and Great Lakes National Aquaculture Initiative

National Sea Grant College Program

Depending on appropriations, NOAA National Sea Grant College Program (NOAA Sea Grant) expects to have available a total of $7,000,000 to $11,500,000 across fiscal years 2018, 2019 and 2020 as part of the Sea Grant National Aquaculture Initiative (NAI). As part of the NAI, this competition is designed to foster the expansion of a sustainable U.S. ocean, coastal and Great Lakes aquaculture sector by addressing one or more of the following priorities: (a) supporting the development of emerging systems or technologies that will advance aquaculture in the U.S., including projects that will help stimulate aquaculture production by nascent industries; (b) developing and implementing actionable methods of communicating accurate, science based messages and information about the benefits and risks of U.S. marine aquaculture to the public; and (c) increasing the resiliency of aquaculture systems to natural hazards and changing conditions. Successful applications must describe projects that clearly address major constraints, barriers or hurdles limiting aquaculture production in the U.S. Complete proposals are due from eligible parties to Sea Grant programs on March 2, 2018 at 5 p.m. local time. Proposals from Sea Grant programs are due in grants.gov by March 30, 2018

Interested applicant may obtain the full Federal Funding Opportunity announcement by visiting grants.gov opportunity number NOAA-OAR-SG-2018-2005489. 

Applicants are strongly encouraged to reach out to their Sea Grant Program one to two months prior to the Sea Grant program

New tool helps oyster growers prepare for changing ocean chemistry

NOAA Research

For Bill Mook, coastal acidification is one thing his oyster hatchery cannot afford to ignore.

Mook Sea Farm depends on seawater from the Gulf of Maine pumped into a Quonset hut-style building where tiny oysters are grown in tanks. Mook sells these tiny oysters to other oyster farmers or transfers them to his oyster farm on the Damariscotta River where they grow large enough to sell to restaurants and markets on the East Coast.
