OA Alliance Webinar Recording (60 minutes) 

April 15, 2020

Are we already seeing impacts of OA?  Biological studies and research from around the world.

Agenda- PART ONE

(1) Welcome and Introductions

Ms. Jessie Turner, OA Alliance, Project Coordinator

(2) Ocean Acidification Impacts on Dungeness Crab in the Wild

Dr. Nina Bednarsek, Southern California Coastal Water Research Project, Biogeochemistry Department, Senior Scientist

  • How is ocean acidification impacting Dungeness crab in the environment? (Growth and reproduction, including population size and size of individual crab?)
  • Were there any findings regarding sensory structures? What is the implication/importance of impacts to sensory structures?
  • What is the significance of this study being done “in situ”?
  • What’s next with this research project? Will it be expanded?

(3) Examining OA impacts on Lobster and Northern Shrimp in the Northern Atlantic

Dr. Piero Calosi, University of Quebec, Department of Biology, Chemistry and Geography, Professor of Marine Biology

  • What studies have been conducted regarding OA impacts to lobster and Northern Shrimp in the Atlantic? What did they show?
  • Why were these two species chosen to study? And what are the strengths and limitations in picking these two species as a beginning focus?  
  • What are you finding about the combined ecological impacts of ocean acidification and warming?  How can this information help inform adaptation strategies and responsive management decisions?
  • What’s the importance of understanding and predicting species distribution?
  • How can enhanced and expanded modeling help decision makers better prepare for future changes?


Agenda- PART TWO

(4) Intra- and inter-generational resilience to OA in the New Zealand Green-lipped mussel

Dr. Norman Ragg, Cawthron Institute, Shellfish Physiology and Aquaculture, Senior Scientist  

  • Why focus on green-lipped mussels?  Why are they important (economically/ ecologically?)
  • What are the relative vulnerabilities of each life stage?
  • What is the potential to influence resilience in offspring? (both genetic and non-genetic mechanisms)
  • Communicating findings to stakeholders including governments and non-government entities (what are the next steps?)

(5) A Global Approach to Evaluating the Impact of Ocean Acidification on Seafood

Dr. Marc Metian, International Atomic Energy Agency, Ocean Acidification International Coordinating Center (OA-ICC), Radioecologist

  • What is the IAEA, and why is it involved in OA research?
  • Overview of the new CRP project:
    • Collect and compare worldwide data on the impacts of ocean acidification on key local seafood species through a collaborative approach involving Member States of the IAEA from across the globe.
  • Why is it important to continue to build long-term studies on ocean acidification’s impacts on socio-economically important seafood species?
  • How does this work relate to United Nations Sustainable Development Goal 14.3? 



(6) What is a “Burkolator?” Expanding Monitoring Partnerships with Seafood Industries

Dr. Burke Hales, Oregon State University, College of Earth, Ocean and Atmospheric Sciences, Ocean Ecology and Biogeochemistry, Professor

  • What is a “Burkolator”?—Brief history and background. Why were they created?  What information do they produce? Who do they serve?  And where are they located?
  • Why is monitoring/ forecasting so important, specifically to the seafood industry?
  • Overview of new project—in partnership with Ocean Foundation—that seeks to expand monitoring capacity for seafood growers.
