Scientists and NOAA Hollings scholars at the Northeast Fisheries Science Center (NEFSC) are studying how Atlantic silverside, one of the most common fishes on the Atlantic Coast and an important diet component of many larger fishes of this region, are impacted by changes in ocean acidification (increased CO2, lower pH), increased temperature, and lower dissolved
JANUARY 16TH, 2018 NOAA OAP Director, Libby Jewett, is participating in a working group at the United Nations Educational, Scientific and Cultural Organization (UNESCO). The group is working to develop methodology and concrete actions for United Nations Standard Development Goals on ocean acidification.
Florida State University News For thousands of years, California mussel shells have shared a relatively uniform mineralogical makeup — long, cylindrical calcite crystals ordered in neat vertical rows with crisp, geometric regularity. But in a study published this week in the journal [EasyDNNnewsLink|82], McCoy and her team suggest that escalating rates of ocean acidification are shaking up that
Marine Resources Advisory Council 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
Tiffany Grunzel, University of Washington Communications Leadership Program Ocean acidification could have deep impacts for salmon in the Puget Sound. Tiffany Grunzel from the University of Washington Communications Leadership program, interviews Dr. Shallin Busch (NOAA), Dr. Chase Williams (UW), and Robert Purser Jr. (Susquamish Fisheries) about the direct and indirect impacts of ocean acidification on salmon
ARC CoE Coral Reef Studies Some species of coral may be better adapted to respond to ocean acidification, according to research published in [EasyDNNnewsLink|78].
Bioeconomic models are a multidisciplinary tool that use oceanography, fisheries science and social science to assess socioeconomic impacts. Funded by the Ocean Acidification Program, researchers at the Alaska Fisheries Science Center use a bioeconomic model to study the impacts of ocean acidification on Eastern Bering Sea crab, northern rock sole and Alaska cod. The goal is to predict how ocean acidification will affect abundance yields and income generated by the fisheries. This work informs the potential economic impacts of ocean acidification and future decision making and research planning.
Long-term declines of red king crab in Bristol Bay, Alaska may be partially attributed to ocean acidification conditions. These impacts may be partially responsible for the fishery closures during the 2021–2022 and 2022–2023 seasons. Researchers found that ocean acidification negatively impacts Alaskan crabs generally by changing physiological processes, decreasing growth, increasing death rates and reducing shell thickness. Funded by the Ocean Acidification Program, scientists at the Alaska Fisheries Science Center continue to investigate the responses of early life history stages and study the potential of various Alaska crabs to acclimate to changing conditions. Results will inform models that will use the parameters studied to predict the effects of future ocean acidification on the populations of red king crab in Bristol Bay as well as on the fisheries that depend on them. Fishery managers will better be able to anticipate and manage stocks if changing ocean chemistry affects stock productivity and thus the maximum sustainable yield.
Understanding seasonal changes in ocean acidification in Alaskan waters and the potential impacts to the multi-billion-dollar fishery sector is a main priority. Through work funded by NOAA’s Ocean Acidification Program, the Pacific Marine Environmental Laboratory developed a model capable of depicting past ocean chemistry conditions for the Bering Sea and is now testing the ability of this model to forecast future conditions. This model is being used to develop an ocean acidification indicator provided to fisheries managers in the annual NOAA Eastern Bering Sea Ecosystem Status Report.
The NOAA Ocean Acidification Program (OAP) works to prepare society to adapt to the consequences of ocean acidification and conserve marine ecosystems as acidification occurs. Learn more about the human connections and adaptation strategies from these efforts.
Adaptation approaches fostered by the OAP include:
Using models and research to understand the sensitivity of organisms and ecosystems to ocean acidification to make predictions about the future, allowing communities and industries to prepare
Using these models and predictions as tools to facilitate management strategies that will protect marine resources and communities from future changes
Developing innovative tools to help monitor ocean acidification and mitigate changing ocean chemistry locally
Drive fuel-efficient vehicles or choose public transportation. Choose your bike or walk! Don't sit idle for more than 30 seconds. Keep your tires properly inflated.
Eat local- this helps cut down on production and transport! Reduce your meat and dairy. Compost to avoid food waste ending up in the landfill
Make energy-efficient choices for your appliances and lighting. Heat and cool efficiently! Change your air filters and program your thermostat, seal and insulate your home, and support clean energy sources
Reduce your use of fertilizers, Improve sewage treatment and run off, and Protect and restore coastal habitats
You've taken the first step to learn more about ocean acidification - why not spread this knowledge to your community?
Every community has their unique culture, economy and ecology and what’s at stake from ocean acidification may be different depending on where you live. As a community member, you can take a larger role in educating the public about ocean acidification. Creating awareness is the first step to taking action. As communities gain traction, neighboring regions that share marine resources can build larger coalitions to address ocean acidification. Here are some ideas to get started:
