Ocean acidification (OA) in the Gulf of America (GOA) is driven by different physical and biogeochemical factors across the region, with most data available on the eastern and northern regions and very little information from the western or southern parts of the GOA. Upwelling dominates OA variability on the West Florida Shelf, while the northern
Drs. Samantha Siedlecki, Clarissa Anderson, Jan Newton and Barb Kirkpatrick discuss how corrosive, hypoxic, and harmful algal bloom (HAB) events in coastal waters are of increasing concern to local fisheries and managers. Many important species around the country in coastal waters are currently experiencing or are expected to feel effects of ocean acidification and harmful algal
Hans Paerl of University of North Carolina- Chapel Hill discusses how estuaries receive and process nutrient loads generated in coastal watersheds and often exhibit accelerated rates of primary production (eutrophication), phytoplankton blooms, hypoxia and associated water quality and habitat declines. As such, they are highly dynamic with respect CO2 fixation and mineralization of autochthonous organic
Raphe Kudela of University of California Santa Cruz shares how the US west coast is experiencing increasing environmental stress, as are all coastal regions globally. Unlike some other regions, eastern boundary currents naturally experience large swings in pH and decadal oscillations in temperature, making the west coast an ideal location for observing the interactive effects
Dr. Chris Gobler discusses how harmful blooms and ocean acidification have emerged as two expanding threats to coastal ecosystems. Regardless of how acidification affects HABs, it is a clear environmental threat to a suite of calcifying invertebrates as well as other marine organisms including early life stage fish. While HABs and acidification co-occur on coastal
The Gulf of Mexico Coastal Acidification Network (GCAN) proudly presents Julianna Mullen, the Community Manager of the Ocean Acidification Information Exchange (OAIE). The OAIE is an online community for professionals involved with or interested in ocean and coastal acidification. Ms. Mullen will give an overview of the website, explain how individuals can join, and discuss
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:
