Helping the State visualize what’s at stake as oceans acidify

OVERVIEW: UNDERSTANDING OA RISKS TO CALIFORNIA’S LIVING MARINE RESOURCES

Ocean acidification (OA) is a complex issue that has the potential to alter marine food webs and ecosystems in California, with direct and indirect impacts to valuable marine fisheries and the aquaculture industry. Currently, state agencies working to understand the risks OA poses to coastal species, ecosystems, and human communities – an essential step to helping those at risk prepare for what’s at stake as coastal oceans continue to acidify.

VISUALIZING IMPACTS OF OA TO LIVING MARINE RESOURCES IN CALIFORNIA

As a first step towards illuminating potential natural resource management solutions, Ocean Science Trust is working closely with the Ocean Protection Council and other partners to demonstrate the potential impacts of OA on important species and ecosystems in California. We are undertaking a synthesis of current scientific understanding and developing communications materials for use by resources managers. The species included in the synthesis represent a diverse subset of species considered as ocean climate indicators, commercially, recreationally, and/or ecologically important. This list was selected by the project team and vetted and augmented by OPC, CDFW, and aquaculture representatives.

WORKSHOP: DEFINING OCEAN ACIDIFICATION HOTSPOTS IN CALIFORNIA

Building on this assessment, Ocean Science Trust will host a workshop in fall 2018, to help managers and decision-makers incorporate OA impacts information into relevant management decisions, prioritize efforts to address these impacts, and determine where to allocate resources to further increase understanding. This workshop will bring together managers, policy makers, and scientists to better understand the concept of OA hotspots, ensure it is usable by state decision-makers, and identify key gaps in data and information that inhibit action.

 

Findings from this work may also:

  • Help identify research and data gaps to understanding OA impacts to California’s fishery resources
  • Inform species selection for a modeling exercise to identify species vulnerability thresholds
  • Provide the groundwork for a quantitative OA or climate vulnerability assessment for California or the West Coast
