A Sentinel for Change: Secrets along the seafloor in Olympic Coast

ocean acidification / By

Whether you arrive on the Olympic Peninsula by land, sea, or air, you sense its remote, rugged and vast environment immediately. The Olympic Coast is home to productive waters which sustain thriving marine and coastal communities that have long supported the region’s tribal peoples. Ocean waters quickly deepen just offshore, boasting canyons which extend almost a mile below the surface – and have yet to be fully explored.

The spirit of collaboration aboard Gulf of America cruise

Coastal Acidification, OA News, ocean acidification / By

NOAA Research & Ocean Acidification Program  This summer, NOAA and partner scientists will conduct their most collaborative ocean acidification sampling of the Gulf of America (fomerly known as Gulf of Mexico) yet. Set to depart today, July 18th, the Gulf of Mexico Ecosystems and Carbon Cruise (GOMECC-3) will travel through international waters with 24 scientists

Georgetown Journal of International Affairs  or those who make their living farming oysters in the states of Washington and Oregon, the widespread mortality of larvae at several hatcheries between 2005 and 2009 was alarming and potentially devastating. After intense scientific scrutiny and collaboration among industry, government, and academic scientists, the culprit was eventually identified: corrosive seawater.

Acidified ocean water widespread along North American West Coast

OA News, ocean acidification / By

Oregon State University  A three-year survey of the California Current System along the West Coast of the United States found persistent, highly acidified water throughout this ecologically critical nearshore habitat, with ‘hotspots’ of pH measurements as low as any oceanic surface waters in the world.

MAPCO2 Buoys at NCRMP CLASS III Sites in US Coral Reefs

OA News / By

The long-term observations of carbonate chemistry at U.S.-affiliated coral reef sites are critical to understanding the impact of ocean acidification (OA) on coral ecosystems over time. This effort addresses NOAA’s Ocean Acidification Program (OAP) requirements for Monitoring of Ocean Chemistry by building and maintaining the coral reef portion of the OA monitoring network. This supports funding shortfalls associated with the NCRMP Class III MAPCO2 buoys at Cheeca Rocks and Kaneohoe Bay. Furthermore, this provides resources for the procurement of a new MAPCO2 buoy slated for deployment in Fagatele Bay, American Samoa in FY18, to establish the 2nd of three planned NCRMP Class III sites in the U.S. Pacific.

Development of Ocean Acidification “pHyter” – Plankton Monitoring Tools & Curriculum

education & outreach / By

NOAA’s National Marine Sanctuaries of the West Coast Region (Olympic Coast, Greater Farallones, Cordell Bank, Monterey Bay and Channel Islands) will partner with Flathead Valley Community College, NOAA’s National Centers for Coastal Ocean Science (NCCOS) and NOAA’s Northwest Fisheries Science Center (NFSC), to increase accessibility and understanding of tools and protocol for ocean acidification monitoring through citizen science and education programs.

Humans and the ocean are inextricably interconnected, with all humans relying on ocean ecosystem outputs such as oxygen, water and food.  Currently, ocean ecosystems are threatened by multiple global change stressors, including ocean acidification (OA).  The development of OA monitoring tools and education curriculum will be instrumental in providing the public with a better understanding of the process of OA and impacts of a more acidic environment to valuable ocean ecosystems.

NOAA’s West Coast Region (WCR) sanctuaries will work with external partner Dr. David Long, of Flathead Valley Community College, to pilot a field-based pH-measuring instrument called ”pHyter” with WCR sanctuaries’ OA education and outreach programs, including citizen science, teacher workshops and student field investigations. Dr. Long  and his students recently developed pHyter: a hand-held chemical indicator-based spectrophotometric pH- measuring device.  OAP funds will support the expansion of pHyter instrument capabilities to permit iPhone and android apps to interface and upload to the international GLOBE Program GIS database, increasing accessibility of pH data.

Research shows ocean acidification is spreading rapidly in the Arctic

OA News / By

NOAA Oceanic and Atmospheric Research  Ocean acidification is spreading rapidly in the western Arctic Ocean in both area and depth, potentially affecting shellfish, other marine species in the food web, and communities that depend on these resources, according to new research published in Nature Climate Change by NOAA, Chinese marine scientists and other partners.

MIT Sea Grant Announces Three Newly Funded Projects Studying Ocean Acidification

Coastal Acidification, OA News / By

MIT Sea Grant  MIT Sea Grant has selected three research projects for funding from our annual request for proposals. The projects focus on developing new ocean acidification sensor technology and using modeling techniques to consolidate historical data to inform future coastal ocean acidification monitoring.

Understanding seasonal changes in ocean acidification in Alaskan waters and the potential impacts to the multi-billion-dollar fishery sector is a main priority. Through work funded by NOAA’s Ocean Acidification Program, the Pacific Marine Environmental Laboratory developed a model capable of depicting past ocean chemistry conditions for the Bering Sea and is now testing the ability of this model to forecast future conditions. This model is being used to develop an ocean acidification indicator provided to fisheries managers in the annual NOAA Eastern Bering Sea Ecosystem Status Report.

ADAPTING TO OCEAN ACIDIFICATION

The NOAA Ocean Acidification Program (OAP) works to prepare society to adapt to the consequences of ocean acidification and conserve marine ecosystems as acidification occurs. Learn more about the human connections and adaptation strategies from these efforts.

Adaptation approaches fostered by the OAP include:

FORECASTING

Using models and research to understand the sensitivity of organisms and ecosystems to ocean acidification to make predictions about the future, allowing communities and industries to prepare

MANAGEMENT

Using these models and predictions as tools to facilitate management strategies that will protect marine resources and communities from future changes

TECHNOLOGY DEVELOPMENT

Developing innovative tools to help monitor ocean acidification and mitigate changing ocean chemistry locally

TAKE ACTION WITH YOUR COMMUNITY

You've taken the first step to learn more about ocean acidification - why not spread this knowledge to your community?

Every community has their unique culture, economy and ecology and what’s at stake from ocean acidification may be different depending on where you live.  As a community member, you can take a larger role in educating the public about ocean acidification. Creating awareness is the first step to taking action.  As communities gain traction, neighboring regions that share marine resources can build larger coalitions to address ocean acidification.  Here are some ideas to get started:

  1. Work with informal educators, such as aquarium outreach programs and local non-profits, to teach the public about ocean acidification. Visit our Education & Outreach page to find the newest tools!
  2. Participate in habitat restoration efforts to restore habitats that help mitigate the effects of coastal acidification
  3. Facilitate conversations with local businesses that might be affected by ocean acidification, building a plan for the future.
  4. Partner with local community efforts to mitigate the driver behind ocean acidification  – excess CO2 – such as community supported agriculture, bike & car shares and other public transportation options.
  5. Contact your regional Coastal Acidification Network (CAN) to learn how OA is affecting your region and more ideas about how you can get involved in your community
