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.
The Environmental Assessment Program (EAP) program within the Department of Ecology is looking to fill a Marine Scientist (Natural Resource Scientist 2) position. Applications are due April 24, 2018.
This position is located at our Headquarters Building in Lacey, WA but conducts work statewide. This position is responsible for conducting marine water quality monitoring, with a focus on ocean acidification. Responsibilities include implementing the addition of ocean acidification-relevant parameters to Ecology's marine waters monitoring program in Puget Sound. This position is also responsible for oceanographic sampling gear preparation and use, instrument calibration (CTD and other electronic sensors), laboratory sample analyses, data analysis, and report writing. The data collected is used to determine the status and trends of marine water quality in context to ocean acidification in Washington state.

The Olympic Coast, located in the Pacific Northwest U.S., stands as a region already experiencing effects of ocean acidification (OA). This poses risks to marine resources important to the public, especially local Native American tribes who are rooted in this place and depend on marine treaty-protected resources. This project brings together original social science research, synthesis of existing chemical and biological data from open ocean to intertidal areas, and model projections, to assess current and projected Olympic Coast vulnerabilities associated with OA. This critical research aims to increase the tribes’ ability to prepare for and respond to OA through respective community-driven strategies. By constructing a comprehensive, place-based approach to assess OA vulnerability, decision-makers in the Pacific Northwest will be better able to anticipate, evaluate and manage societal risks and impacts of OA. This collaborative project is developed in partnership with tribal co-investigators and regional resource managers from start to finish and is rooted in a focus on local priorities for social, cultural, and ecological health and adaptive capacity.
The Washington state governor’s appointed board, the Marine Resources Advisory Council, released its first update in five years to the state’s coordinated response to ocean acidification. In the five years since the Blue Ribbon Panel’s report, there have been significant scientific advances and progress made on the 42 recommended actions. The report highlights the new research that justifies more concerted efforts to combat ocean acidification. The report is publicly available [EasyDNNnewsLink|80].
Eleven NOAA and Washington Sea Grant scientists from the National Ocean Service, National Marine Fisheries Service and the Office of Oceanic and Atmospheric Research served on the Blue Ribbon “Refresh” Panel and contributed to the report.

The North Pacific Research Board (NPRB) announces the release of its Core Program Request for Proposals (RFP). The 2018 RFP has an anticipated funding amount of $4.45 million. The North Pacific Research Board specifically lists ocean acidification as a topic of interest for proposed projects.
