BC OAH Action Plan

The BC OAH Action aims to determine the state of knowledge related to ocean acidification and hypoxia in BC’s coastal waters, with long-term goals for addressing knowledge gaps and developing adaptation and mitigation strategies to support the fisheries and aquaculture sectors, traditional harvesters, and other BC seafood interests.


Tsleil-Waututh Nation’s Climate Action Initiatives

Tsleil-Waututh members have observed the effects of climate change in our territory for decades. OA is a concern to TWN, along with other ocean-related effects of climate change. Burrard Inlet is becoming more acidic, and research is underway to determine whether the cause is disproportionately associated with OA or if the reduction in pH is attributed to urban and industrial inputs.


In 2019, the City of Vancouver declared a climate emergency, and in response focused on drastically cutting the city’s greenhouse gas emissions. The City of Vancouver has also registered our ocean acidification Framework, as a Voluntary Commitment to help support the implementation of the UN Sustainable Development Goal 14, Life Below Water.

Baynes Sound Data

This project aims to better understand the short- and long-term variability that occurs within these productive waters. With more data, it is hoped that producers will have the information needed to make the best decisions for their harvest. This online resource gives users access to real time ocean monitoring data in Baynes Sound.


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?

Acidification in Our Oceans

This infographic developed by NOAA aims to teach the basics of ocean acidification and to provide information on what the reader can do to help this global problem.


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.

Ocean Acidification Building Blocks of the Sea

This educational resource from NOAA, OAP and the National Marine Sanctuaries aims to have students understand the impact human activities can have on the chemistry/health of the ocean, and how changes in ocean ecosystems impact ocean and human life.

Whale Jenga: A Food Web Game

This educational resource from NOAA and the National Marine Sanctuaries aims to have students understand how organisms are connected through the marine food web and how small changes to to food webs can have larger scale impacts.


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.

BC Climate Preparedness and Adaptation Strategy

B.C.’s Climate Preparedness and Adaptation Strategy outlines four pathways to help ensure we stay safe and to prepare for a changing climate. The strategy highlights B.C.'s overall direction and actions that the Province is taking to help better understand and adapt to the impacts of climate change, and is supported by more than $500 million in funding.

DFO: Ocean Acidification Video

This video from the DFO-Canada outlines how the levels of carbon dioxide in the atmosphere have continued to increase due to human activities, lowering the pH of the ocean and making it more acidic. This process of ocean acidification increasingly affects ecosystems and those communities that directly rely on the ocean.

Commonwealth Blue Charter: Ocean Acidification Policymakers Handbook

The Commonwealth Blue Charter helped put together an Ocean Acidification policymakers handbook. This contains many of the tools that a policy maker needs to be acquainted with to effectively make decisions about Ocean Acidification.

DFO:What is Ocean Acidification?

Ocean acidification is a global threat with potential impacts on marine food webs, ecosystem productivity, commercial fisheries and global food security. This threat has prompted the international scientific community, including Fisheries and Oceans Canada, to investigate the implications of this significant international governance issue.
