OA Alliance

The OA Alliance is an international organization whose goal is to create a network of governments and organizations. They use this network to take action against the growing threat of Ocean Acidification to protect coastal communities all over the world.

Climate Change and Ocean Acidification: Olympic Coast- Video

 In recent years, shellfish growers in Washington state have needed to develop monitoring and treatment practices to avoid spawning failures that have been linked to periodic upwelling of more acidic ocean waters. Read this overview of OA research on the Olympic coast!

Back to Blue Initiative: An Ocean Crisis in the Making

The Back to Blue Initiative has created an interactive webpage that educates the user on the basics of ocean acidification. These basics are broken down into an introduction, the science, the impacts, and soultions?


Understanding OA

Learn how our oceans are absorbing increasingly more carbon dioxide from the atmosphere, leading to lower pH and greater acidity with this educational resource from NOAA. Ocean acidification is fundamentally changing the chemistry of the world’s oceans and threatening our marine resources.

Ocean Acidification: pH and the Ocean's Balance

This educational resource from NOAA, OAP and the National Marine Sanctuaries aims to have students understand the pH is a measurement of ocean acidification, understand the pH scale, and the impacts that small changes to this scale can have.


Dungeness Crab Case Study Resources

Dungeness crab is a valuable species throughout the National Marine Sanctuaries of the West Coast from Washington state to throughout California. This communication toolkit is designed for educators and communicators to use to teach others about the impact of ocean acidification on Dungeness crab.
