Understanding the exposure of the nation’s living marine resources such as shellfish and corals to changing ocean chemistry is a primary goal for the NOAA OAP. Repeat hydrographic surveys, ship-based surface observations, and time series stations (mooring and ship-based) in the Atlantic, Pacific, and Indian Oceans have allowed us to begin to understand the long-term changes in carbonate chemistry in response to ocean acidification.
There are currently 19 OAP-supported buoys in coastal, open-ocean and coral reef waters which contribute to NOAA's Ocean Acidification Monitoring Program, with other deployments planned.
Currently, there are two types of floating devices which instruments can be added in order to measure various ocean characteristics - buoys and wave gliders. Buoys are moored, allowing them to remain stationary and for scientists to get measurements from the same place over time. The time series created from these measurements are key to understanding how ocean chemistry is changing over time. There are also buoys moored in the open-ocean and near coral reef ecosystems to monitor the changes in the carbonate chemistry in these ecosystems. The MAP CO2 sensors on these buoys measure pCO2 every three hours.

Research cruises are a way to collect information about a certain ecosystem or area of interest.
For decades, scientists have learned about physical, chemical and biological properties of the ocean and coasts by observations made at sea. Measurements taken during research cruises can be used to validate data taken by autonomous instruments. One instrument often used on research cruises is a conductivity, temperature, and depth sensor (CTD), which measures the physical state of the water (temperature, salinity, and depth). The sensor often goes in the water on a rosette, which also carries niskin bottles used to collect water samples from various depths in the water column. Numerous chemical and biological properties can be measured from water collected in niskin bottles.
Ships of Opportunity (SOPs) or Volunteer Observing Ships (VOSs) are vessels at sea for other reasons than ocean acidification studies, such as commercial cargo ships or ferries.
The owners of these vessels allow scientific instrumentation that measures ocean acidification (OA) parameters to be installed and collect data while the ship is underway. This allows data on ocean chemistry to be collected in many remote areas of the world's ocean, such as high latitude waters, long distances from land (e.g. mid-basin waters), and places not easily accessible by research cruises. These partnerships have greatly increased the spatial coverage of OA monitoring world-wide. To learn more, check out the Ships of Opportunity programs established by the NOAA Pacific Marine Environmental Laboratory (PMEL) and the NOAA Atlantic Oceanographic Marine Laboratory (AOML).
Scientists at the NOAA Pacific Marine Environmental Laboratory (PMEL) are working with engineers at Liquid Robotics, Inc. to optimize a Carbon Wave Glider.
This instrument (pictured above) can be driven via satellite from land. Carbon Wave Gliders can be outfitted with pCO2, pH, oxygen, temperature and salinity sensors, and the glider’s equipment takes measurements as it moves through the water. The glider’s motion is driven by wave energy, and its sensors are powered through solar cells and batteries, when needed.
NOAA’s Coral Reef Conservation Program (CRCP) in partnership with OAP is engaged in a coordinated and targeted series of field observations, moorings and ecological monitoring efforts in coral reef ecosystems.
These efforts are designed to document the dynamics of ocean acidification (OA) in coral reef systems and track the status and trends in ecosystem response. This effort serves as a subset of a broader CRCP initiative referred to as the National Coral Reef Monitoring Plan, which was established to support conservation of the Nation’s coral reef ecosystems. The OAP contributes to this plan through overseeing and coordinating carbonate chemistry monitoring. This monitoring includes a broadly distributed spatial water sampling campaign complemented by a more limited set of moored instruments deployed at a small subset of representative sites in both the Atlantic/Caribbean and Pacific regions. Coral reef carbonate chemistry monitoring is implemented by researchers at the NOAA Atlantic Oceanographic & Meteorological Laboratory (AOML) and NOAA's PIFSC Coral Reef Ecosystems Division.
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).
Students from University of Washington's (UW) College of Computer Science & Engineering (CSE), are looking for local opportunities to apply their newly-acquired skills and gain experience in preparation for a competitive job market. We propose to leverage this local (and economical) tech resource by hiring student interns interested in working with the PMEL Carbon Program's large data collections and developing novel interactive tools for data visualization and communication that would serve the broader community of scientists, resource managers, and other stakeholders. We also propose to develop new 2D and/or 3D visualizations of observational data, model results, model-data comparisons, and conceptual diagrams related to OAP-funded work in the California Current Large Marine Ecosystem to improve the coastal OA community's ability to communicate with stakeholders about observed and forecasted conditions and potential impacts. This work will build on an existing partnership with UW's Center for Environmental Visualization (CEV), which built the PMEL Carbon Program website in 2010 and recently updated our antiquated Google Earth data portal (www.pmel.noaa.gov/co2/map/index). The proposed work will contribute to improving the public's access to and ability to interact with data generated by the NOAA Ocean Acidification Observing Network (NOA-ON) with the goal of increasing awareness and understanding of ocean acidification (OA).
