OAP Deputy Director contributes to effort to identify research need to understand impacts and explore adaptation in Arctic

April 28th, 2018

OAR OAP Deputy Director participated in the AMAP/EU-PolarNet Stakeholder Workshop on Research Needs on Climate-Related Effects on the Arctic Cryosphere and Adaptation Options. Participants discussed research issues in relation to both the need for further scientific understanding of the impacts of the rapidly changing climate on the Arctic cryosphere and the need for investigation of options for adaptation to these changes by Arctic communities and residents.

Assess, anticipate, adapt: Vulnerability and Responses to Ocean Acidification

NOAA Ocean Acidification Program

There are areas in the United States where marine resources and the communities and industries that depend on them are particularly vulnerable to the impacts of ocean acidification. In three US regions, our understanding of vulnerability is being advanced by coupling ocean and social science data to equip communities and industries with the information needed to evaluate, anticipate, and adapt to ocean acidification.

OAP Director participates in workshop focused on expanding ocean acidification stakeholders in Latin America

March 17th, 2018

OAP Director, Libby Jewett, will participate in and present at a workshop focused on expanding ocean acidification stakeholders in Latin America. The workshop will take place in Santa Marta, Colombia March 17th-22nd. Dr. Jewett will be presenting both the overview of the science of Ocean Acidification (OA) and its implications for our world's oceans and an introduction to the work of the Global OA Observing Network which she co-chairs.

Low pH in Coastal Waters of the Gulf of Maine: A Data Synthesis-Driven Investigation of Probable Sources, Patterns and Processes Involved

David W. Townsend, University of Maine

Coastal Maine supports valuable lobster, clam, oyster and other shellfish industries that comprise >90% of Maine’s record $616M landed value last year. Earlier monitoring efforts in Maine and New Hampshire have documented periods of unusually acidic conditions in subsurface waters of Maine’s estuaries, which may be driven by episodic influxes of waters from the Gulf’s nutrient-rich, highly productive coastal current system. Sources of acidity to the estuaries also include the atmosphere, freshwater fluxes, and local eutrophication processes, all modulated by variability imparted by a number of processes.This project is a data synthesis effort to look at long-term trends in water quality data to identify the key drivers of acidification in this area. Extensive data sets dating back to the 1980s (including carbonate system, hydrography, oxygen, nutrients, and other environmental variables) will be assembled, subjected to QA/QC, and analyzed to assess acidification events in the context of landward, seaward and direct atmospheric sources, as may be related to processes operating on tidal to decadal timescales. Such analyses are requisite for any future vulnerability assessments of fishery-dependent communities in Maine and New Hampshire to the effects of coastal acidification.

Vulnerability and Adaptation to Ocean Acidification Among Pacific Northwest Mussel and Oyster Stakeholders

David J. Wrathall, George Waldbusser, and David Kling, Oregon State University

Ocean acidification (OA) is already harming shellfish species in the Pacific Northwest, a global hotspot of OA. While OA poses a threat to regional communities, economies, and cultures that rely on shellfish, identified gaps remain in adaptive capacity and vulnerability of several stakeholders. This project will address these gaps by extending long-standing collaborative OA vulnerability research with shellfish growers to include other shellfish users (e.g. port towns, Native American tribes and shellfish sector employees). The project includes five objectives: 1) Map variations in shellfisheries’ exposure to OA and identify those that are most sensitive, 2) quantify production losses from OA and costs of investment in adaptation 3) Identify potential pathways for adaptation, 4) identify key technological, institutional, legislative, financial and cultural barriers to OA adaptation, 5) evaluate the cost of potential adaptation strategies, and develop behavioral models to predict the likelihood of users adopting specific adaptation strategies. The research is designed to identify key vulnerabilities, determine the cost of OA to Pacific Northwest shellfish stakeholders, and to model adaptation pathways for maximizing resilience to OA. The adaptation framework developed here will be replicable in other shellfisheries yet to experience OA impacts.
