Working with the Carbon Group at NOAA’s Pacific Marine Environmental Lab, we propose to continue the now 4-year time series of real-time, high-frequency measurements of critical core OA parameters on the northern Washington shelf, including regular collection of validation samples. Specifically APL-UW will continue to maintain a heavily-instrumented surface mooring (Cha’ba) providing core OA and support parameters 13 miles WNW of La Push, WA, within the Olympic Coast National Marine Sanctuary, just shoreward and south of the Juan de Fuca Eddy—a known harmful algae bloom (HAB) source (Trainer et al., 2009; Hickey et al., 2013). Cha’ba currently houses a MAPCO2 system and many auxiliary sensors including two pH sensors, several CTDs, two oxygen sensors, an ADCP, and a fluorometer/turbidity sensor. Because of budget limitations, lack of ship time, and possessing only one surface mooring, we are only able to deploy the Cha’ba system for 6-8 mo/yr, typically from March-April through September-October. A LOI is attached to this workplan that would allow for continuous 12 mo/yr deployments in order to bring this to the full requirements of NOAA OAP. Cha’ba’s location, in an upwelling zone and near the source waters to Puget Sound via the Strait of Juan de Fuca, offers key insights. While Cha’ba records surface air and seawater conditions with some depth resolution, NANOOS also supports a subsurface profiling mooring 400m away from Cha”ba, measuring full water-column properties below 20m, soon to be instrumented (US IOOS funding) with a real-time HAB detection system, pH sensor and profiling CTD offering broader context and insights on biological responses. Synergies between OA and HAB toxicity have been suggested (Sun et al., 2011). Continuation of the MAPCO2 effort on Cha’ba with these ancillary data will facilitate analysis to further develop our understanding of shelf processes important to OA variability, prediction, and biological responses.

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

REDUCING OUR CARBON FOOTPRINT

50 more ways to reduce your carbon footprint >

On the Road

Drive fuel-efficient vehicles or choose public transportation. Choose your bike or walk! Don't sit idle for more than 30 seconds. Keep your tires properly inflated.

With your Food Choices

Eat local- this helps cut down on production and transport! Reduce your meat and dairy. Compost to avoid food waste ending up in the landfill

With your Food Choices

Make energy-efficient choices for your appliances and lighting. Heat and cool efficiently! Change your air filters and program your thermostat, seal and insulate your home, and support clean energy sources

By Reducing Coastal Acidification

Reduce your use of fertilizers, Improve sewage treatment and run off, and Protect and restore coastal habitats

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
