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.

Sea Grant & Ocean Acidification Program 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.

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: The following students and projects were funded through this regional initiative:
 Amanda Zahorik  Delaware Sea Grant  Ocean Acidification and microbially-mediated shell calcification in the Eastern oyster, Crassostrea virginica
 Anthony Himes  Virginia Sea Grant  Influence of salinity history on future ocean acidification tolerance in larval Eastern oysters, Crassostrea virginica, in Chesapeake Bay
 Caroline Schwaner  New York Sea Grant  Identifying Molecular Markers associated with Resilience to Ocean Acidification in the Eastern oyster and the Northern quahog
 Elizabeth Wright-Fairbanks  New Jersey Sea Grant  Assessing the susceptibility of Atlantic sea scallops and surf clams to ocean acidification using glider-based monitoring and larval transport models
 Fei Da  Virginia Sea Grant  Chesapeake Bay acidification: From daily forecasts to half-century projections
 Teresa Schwemmer  New York Sea Grant  Physiology-based modeling of estuarine fishes and ecosystems under ocean acidification
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:
 Diana Padilla  New York Sea Grant  Flexing mussels: Does Mytilus edulis have the capacity to overcome effects of Ocean Acidification?
 Bassem Allam  New York Sea Grant  Probing molecular determinants of bivalve resilience to ocean acidification
 Richard Wahle  Maine Sea Grant  Genetic and phenotypic response of larval American lobster to ocean warming and acidification across new England’s steep thermal gradient
 Hannes Baumann  Connecticut Sea Grant   Sensitivity of larval and juvenile sand lance Ammodytes dubius on Stellwagen Bank to predicted ocean warming, acidification and deoxygenation

Assessment of Sociocultural Dimensions of Coastal Change

Assessment of Sociocultural Dimensions of Coastal Change

Washington Sea Grant is synthesizing information on the resilience and vulnerability of communities to coastal hazards such as ocean acidification and leading the design of a participatory, community-based rapid appraisal in several Washington and Oregon communities facing such hazards. This appraisal will assess culturally significant ecosystem variables, such as important food species and communities’ sense of place, and identify anticipated and cumulative threats posed to them.

Tools for Effective Communication of Ocean Acidification Science and Policy

Tools for Effective Communication of Ocean Acidification Science and Policy

Washington Sea Grant, in partnership with state, federal (NOAA) and international scientists and communication experts have released two ocean acidification fact sheets as aids for scientists, science communicators and science policy advisors asked to comment on acidification: “20 Facts About Ocean Acidification” (Nov 2013. revised Feb 2014) and “Ocean Acidification in the Pacific Northwest” (May 2014). They have also been instrumental in the development of NOAA's Sharing Ocean Acidification Resources for Communicators and Educators (SOARCE) webinar series (8 presentations in 2014).

Ocean Acidification Education Tools for K-12 Classrooms

Ocean Acidification Education Tools for K-12 Classrooms

Washington Sea Grant, in partnership with the Suquamish Tribe, and with assistance from teachers, and state and academic education specialists, is developing a curated online collection of Ocean Acidification curricula, teaching tools, and informational resources for high school, middle school and elementary classrooms. The online collection, which will launched in Oct 2014, can be searched using a variety of filters, such as grade band, subject, type of material (i.e. lab activity, presentation, reading and analysis, etc.), and length of activity. This effort supports coastal resilience by building ocean acidification literacy.
