This project will cross-calibrate citizen science monitoring protocols for ocean acidification among independent organizations in the Northeast by developing a replicable citizen science monitoring training program. This will be accomplished by providing trainings and materials specific for volunteer and citizen science audiences through a series of regional workshops. The project team will (1) develop the first replicable citizen science monitoring program in accordance with recently developed EPA guidance document, Guidelines for Measuring Changes in Seawater pH and Associated Carbonate Chemistry in Coastal Environments of the Eastern United States, (2) provide in-person technical trainings and educational materials through an initial series of three regional workshops in Maine, Massachusetts and Connecticut and (3) support the successful use of citizen science participation in research and management by building on the Northeast Coastal Acidification Network’s extensive capacity and stakeholder network.

Ocean acidification science has evolved rapidly over the past decade. This research landscape has shifted in two important directions. First, the scale of investigation, once limited to global or open ocean scale observations, has broadened with focus on resolving local expression and impacts of OA. Second, research that was almost exclusively restricted to understanding and forecasting exposure and impacts is now complimented by studies on the local actions and solutions for OA mitigation and adaptation. These shifts have created new opportunities for a communications arena where the need for local, solutions-based messages have been identified as key barriers to engagement. At the same time, the lack of effective communications tools that make new research knowledge readily accessible to a range of audience groups has also been recognized as a priority area of need.
 
To address these gaps, we propose to develop a series of audience-specific videos that focuses on local actions and solutions that are underway in Oregon to address OA. By telling the stories of 1) a citizen science OA monitoring network, 2) efforts to breed a better (more OA-resistant) oyster, 3) shellfish hatcheries adapting to change, and 4) new benefits from seagrass beds in mitigating OA, we aim to broaden the OA narrative to include messages of positive actions. We will produce videos that are tailored for 3 groups of audiences (estimated numbers reached): high school students that will receive a new OA curriculum module (~200), aquarium visitors on the Oregon Coast (up to 150,000/yr), and engaged stakeholders visiting a new Oregon ocean story map site (~1000) and/or attend public forums on coastal issues (~400).  The project team comprises a partnership between Oregon Sea Grant, and representatives from academic research (Oregon State University) and environmental NGO’s (Surfrider Foundation).

This project will expand the quantity and quality of ocean acidification (OA) monitoring across Northeastern U.S. coastal waters. The new OA data and incorporation of the world’s first commercial total alkalinity (TA) sensor into our regional observing system (NERACOOS) are designed to supply needed baseline information in support of a healthy and sustainable shellfish industry, and to aid in assessments and projections for wild fisheries. In working with partners to develop this proposal, clear concerns were brought forward regarding the potential impacts of increasing ocean acidity that extend from nearshore hatcheries and aquaculture to broader Gulf of Maine finfish and shellfish industries and their management. Stakeholder input and needs shaped the project scope such that both nearshore and offshore users will be served by TA sensor deployments on partner platforms, including time series data collection at an oyster aquaculture site, on the NOAA Ship of Opportunity AX-2 line, and on federal and State of Maine regional fish trawl surveys. In all, five different deployment platforms will be used to enhance ocean acidification monitoring within the Northeast Coastal Acidification Network (NE-CAN) with significant improvement in temporal and spatial coverage.

 Adding the all-new TA measurement capability to the regional observation network will provide more accurate, certain, and reliable OA monitoring, and an important project objective is to demonstrate and relay this information to regional partners. Data products to be developed from the multi-year measurements include nearshore and offshore baseline OA seasonal time series as well as threshold indices tied to acidification impacts on larval production at the Mook Sea Farm oyster hatchery. An outreach and technical supervision component will include the transfer of carbonate system observing technologies to our partners and to the broader fishing industry, resource management, and science communities. NERACOOS will provide data management and communication (DMAC) services and work towards implementing these technological advances into the IOOS network.

Working across four IOOS Regional Associations in partnership with the shellfish industry and other groups affected by ocean acidification (OA), our proposal is divided into four tasks that continue the foundational aspects established to date and expand both technical capacity and the development of new technology with respect to OA observing needs for shellfish growers and other related impacted and potentially vulnerable U.S. industries, governments (tribal, state, local) and other stakeholders. Our proposed work includes development of observing technology, expert oversight intelligence, data dissemination, and outreach and will be executed by a team that includes a sensor technology industry and academic and government scientists. We will: 1) Develop new lower cost and higher accuracy sensor technology for OA monitoring and expand them to new sites; 2) Utilize regional partnerships of users and local experts to implement and provide Quality Assurance/Quality Control (QA/QC) tests of the new OA sensors; 3) Establish data handling and dissemination mechanisms that provide both user-friendly and standards-based web service access that are exportable from the Pacific Coast module to the entirety of U.S. Integrated Ocean Observing System (IOOS); and 4) Provide education and outreach services to stakeholders concerned about and potentially impacted by OA.

The objective of this project is to make significant strides in bridging the gap between scientific knowledge and current management needs by integrating existing biogeochemical model frameworks, field measurements, and experimental work toward the goals of (1) delineating atmospheric and eutrophication drivers of Chesapeake Bay acidification and improve our understanding of estuarine carbonate chemistry, (2) developing a spatially explicit framework to identify shellfish restoration areas most and least prone to acidification impacts, and (3) better understanding feedbacks associated with future environmental conditions and shellfish restoration goals estuary-wide and within a model tributary. This effort includes (1) a field campaign to make the first comprehensive study of the spatial and temporal variability in the carbonate system in Chesapeake Bay, (2) experiments to quantify both carbonate and nutrient exchange between intact oyster reefs and the surrounding water while measuring response of these fluxes to reef structure and acidification, and (3) an advancement in numerical modeling tools to simultaneously simulate the dynamics of eutrophication, hypoxia, carbonate chemistry, and oyster reef growth and interaction with the water-column under present and future conditions.
