Fourth Report on Federally Funded Ocean Acidification Research and Monitoring Activities

The ocean provides vital resources and services for sustaining humankind including food, recreation, transportation, energy, nutrient-cycling, and climate moderation. Through such resources and services, the ocean substantially contributes to the United States economy. Science is only beginning to indicate how changes in seawater chemistry due to ocean acidification may affect marine organisms and ecosystems and the resources and services they provide. But based on studies to date of acidification’s observed and projected impacts on a number of important classes of marine organisms, significant changes in marine ecosystems appear to be likely.

This document is the fourth biennial summary and progress report submitted under the Federal Ocean Acidification Research and Monitoring Act of 2009 (FOARAM Act, P.L. 111-11, Subtitle D). The FOARAM Act specifies that the Subcommittee on Ocean Science and Technology (SOST) under the National Science and Technology Council Committee on Environment, Natural Resources, and Sustainability shall transmit a biennial report to the Committee on Commerce, Science, and Transportation of the Senate and the Committee on Science, Space, and Technology and the Committee on Natural Resources of the House of Representatives that includes:

1. A summary of Federally-funded ocean acidification research and monitoring activities, including the budget for each of these activities; and

2. An analysis of the progress made toward achieving the goals and priorities for the interagency research plan developed by the Subcommittee under section 12405 of the FORARAM Act.

The SOST’s Interagency Working Group on Ocean Acidification produced this report, which summarizes Federal agency activities related to ocean acidification for fiscal years (FY) 2014 and 2015. The report is organized into sections covering geographic regions. Within each region, information is organized by the thematic areas as outlined within the Strategic Plan for Federal Research and Monitoring of Ocean Acidification (Strategic Plan), and then by Federal agency. Some regions did not host activities for every thematic area, and an additional category called “Other ocean acidification research and monitoring activities” is used for items not adequately captured by the Strategic Plan’s themes.

The Appendix provides a summary of expenditure amounts for individual agencies’ ocean acidification research and monitoring activities. In the expenditures tables, activities are classified as either having a primary focus on ocean acidification or being contributing activities that were designed for other purposes but clearly provide information useful for understanding ocean acidification. In FY 2014, Federal agencies provided approximately $27 million (M) toward activities with a primary focus on ocean acidification and an additional $9M for contributing activities. In FY 2015, Federal funding was approximately $18M for primary activities and $9M for contributing activities. The funding decrease from FY 2014 to FY 2015 reflects the National Science Foundation’s front-funding approach to multi-year projects rather than a significant long-term reduction in ocean acidification investments. Primary and contributing activities included monitoring of ocean chemistry and biological impacts, research to understand species-specific and ecosystem responses to ocean acidification, biogeochemical and ecosystem modeling, technology development, assessment of socioeconomic impacts from ocean acidification, education and outreach activities, data management and integration, and other activities.

Ocean acidification in Arctic Report Card


  • The waters of the Arctic Ocean are disproportionately prone to ocean acidification compared to the rest of the global ocean due to the intensity, duration and extent of natural and anthropogenic drivers.
  • Over the next 2-3 decades, it is likely that ocean acidification will continue to intensify, especially over the shallow Arctic shelves. The rapid rate of this change is likely to have detrimental effects on ecosystems that are already under pressure from rising temperatures and other climate-driven stressors.

The West Coast Ocean Acidification and Hypoxia Science Panel: Major Findings, Recommendations, and Actions

Global carbon dioxide (CO2) emissions over the past two centuries have altered the chemistry of the world’s oceans, threatening the health of coastal ecosystems and industries that depend on the marine environment. This fundamental chemical alteration is known as ocean acidification (OA), a phenomenon driven by the oceans absorbing approximately one-third of atmospheric CO2 generated through human activities. Scientists initially observed the impacts of OA on calcifying marine organisms that were having difficulty forming their shells, but additional evidence now indicates that growth, survival and behavioral effects linked to OA extend throughout food webs, threatening coastal ecosystems, and marine-dependent industries and human communities (see Appendix A).

Although OA is a global phenomenon, emerging research indicates that, among coastal zones around the world, the West Coast of North America will face some of the earliest, most severe changes in ocean carbon chemistry. The threats posed by OA’s progression will be further compounded by other dimensions of global climate change, such as the intensification and expansion of low dissolved oxygen – or hypoxic – zones. In the coming decades, the impacts of ocean acidification and hypoxia (OAH), which are already being felt across West Coast systems, are projected to grow rapidly in intensity and extent. Even if atmospheric CO2 emissions are stabilized today, many of the ongoing chemical changes to the ocean are already “locked in” and will continue to occur for the next several decades. Given these challenges, decision-makers must act decisively and in concert now.

In an effort to develop the scientific foundation necessary for West Coast managers to take informed action, the California Ocean Protection Council in 2013 asked the California Ocean Science Trust to establish and coordinate a scientific advisory panel in collaboration with California’s ocean management counterparts in Oregon, Washington and British Columbia. The resulting West Coast Ocean Acidification and Hypoxia Science Panel, comprised of 20 leading scientific experts (see V. The Panelists, page 32), was charged with summarizing the current state of knowledge and developing scientific consensus about available management options to address OAH on the West Coast.

This document, “Major Findings, Recommendations, and Actions” of the Panel, summarizes the Panel’s work and presents Actions that can be taken now to address OAH. The appendices to this document contain a series of two-page synopses that provide more detail on many of the key concepts that are mentioned in the main body. In addition to this document, the Panel has produced a number of longer supporting documents intended for agency program managers and technical audiences (see VI. Additional Panel Products Supporting the “Major Findings,  Recommendations, and Actions,” page 36).

The U.S. West Coast shellfish industry’s perception of and response to ocean acidification: Understanding an ocean stakeholder

The U.S. west coast (Washington, Oregon, and California) shellfish industry is estimated to directly employ 3,200 people and annually contribute more than $270 million to the region’s economy. This industry predominantly cultivates Pacific oysters, introduced from Japan to replace the native and over-harvested Olympia oyster. Ocean acidification (OA) has received worldwide attention from researchers, media, and the public as an urgent environmental and economic issue. Increasing amounts of carbon dioxide (CO2) in the atmosphere from fossil fuel combustion, land use change, and other human activities result in increased CO2 being absorbed by the ocean. OA makes it harder for coral, phytoplankton, shellfish, and other marine organisms to build their shells and skeletal structures. Shellfish larvae are especially sensitive to acidified waters during critical, early life-stage development. Ocean acidification is happening quickly, and this rapid pace of change gives marine ecosystems and coastal stakeholders less time to adapt.

This study focused on commercial shellfish growers and hatcheries in Washington, Oregon, and California, since they support the base of the extended commercial industry and are closely affected by outcomes of OA. The research objectives were to evaluate the shellfish industry’s experience with OA impacts, assess their self-reported understanding of OA, evaluate how experience with OA impacts and understanding influence level of concern, determine which data sources provide the most useful information to the industry, explore the potential for partnership between the industry and researchers, and investigate how the industry perceives adaptation to OA.

Third xFOCE workshop: present status and future developments of in situ ocean acidification experiments

One of the major challenges facing ocean acidification research is the need to expand from single species to communities and ecosystems (Riebesell and Gattuso 2015). Free Ocean CO2 Enrichment (FOCE) experiments were developed to address the need for long term, in situ CO2 manipulation in benthic ecosystems (Gattuso et al. 2014), and to enable community level investigations of the effects of ocean acidification. Theoretically these experiments allow for the precise control of pH in benthic chambers, while maintaining open flow-through conditions including natural background variation in other parameters. xFOCE is the open source technology developed by the Monterey Bay Aquarium Research Institute (MBARI) to enable cost effective and adaptable system design.
