Sea Grant and Ocean Acidification

The National Sea Grant College Program (Sea Grant) funds research, education, and extension projects to improve community understanding of ocean and coastal acidification.

Industries depending on living marine resources are increasingly concerned about impacts of ocean acidification (OA) on marine ecosystems and subsequent social and economic impacts. Sea Grant funded research projects are designed to respond to stakeholder research questions and evaluate local environmental impacts and societal dependence on impacted species, to facilitate adaptive management strategies. As part of a broader NOAA-wide ocean acidification initiative, Sea Grant provides resource to coordinate regional and state efforts and clearly communicate how OA is affecting U.S. waters and living marine resources.








in research funding to support innovative research that furthers the understanding of the effects of OA and related impacts on coastal communities, economies, fisheries and ecosystems

Meet Sea Grant Experts in Ocean Acidification




Wei-Jun Cai, Ph.D.

Professor, College of Earth, Ocean and Environment, University of Delaware - Dr. Wei-Jun Cai is a co-prinicpal investigator on a Delaware Sea Grant-funded project exploring the relationships of nutrients, pH and acidification to explain and possibly predict Delaware Bay water quality shifts over time.




George Waldbusser, Ph.D.

Associate Professor, College of Earth, Ocean, and Atmospheric Sciences, Oregon State University - Dr. George Waldbusser is currently the principal investigator of an Oregon Sea Grant-funded project examining the response of Oregon pink shrimp larvae to ocean acidification and warming.



Carolyn Friedman, Ph.D.

Professor, School of Aquatic & Fishery Sciences, University of Washington - Dr. Carolyn Friedman is a prinicpal investigator on Washington Sea Grant-funded work examining the response of Pacific Northwest bivalve species such as Pacific oysters.


Sea Grant and OAP Partnership


NOAA’s Ocean Acidification Program (OAP) and Sea Grant began a partnership in 2016 to prioritize and invest in regional ocean and coastal acidification research to help coastal communities better adapt to ocean change. This partnership has helped address regional priority research needs and increased regional awareness of OA concerns.

2018 Fellowships

In 2018, the Mid Atlantic Sea Grant Programs and OAP funded a new regional Ocean Acidification Graduate Research Fellowship Program. Six fellowships were awarded through a competitive selection process to provide Masters and Doctoral students two years of funding during the 2018 and 2019 academic years. The fellowship will support student academic expenses, provide professional development opportunities, and facilitate interaction with ocean, coastal, and estuarine acidification stakeholders in the region.  For more information please see the fellowship announcement here:

2016 Research projects

In 2016, the Northeast Sea Grant Consortium, in partnership with OAP, funded four 2-year research projects to address the impacts of OA on key resource species in the northeast as an aid to assist coastal communities in adapting to current and future OA conditions in the region. The following ongoing research projects were funded through this regional initiative:
