The Basics of Ocean Acidification in Alaska

Since the beginning of the Industrial Revolution the oceans have absorbed hundreds of billions of tons of carbon dioxide (CO₂) released into the atmosphere by the burning of fossil fuels such as coal, oil and natural gas.

Today, approximately 70 million tons of CO₂ is released into the atmosphere from smoke stacks and tail pipes around the world each day. About 30% of that, or 22 million tons, are absorbed by the oceans.

The greater the concentration of CO₂ in the air, the more is absorbed. The result is ocean acidification, sometimes called the “evil twin” to climate change.

Ocean acidification reduces the availability of calcium carbonate that shell-making life forms need to build shells, including crab, oysters, coral, and, importantly, plankton.

Alaskan jobs, our communities and our fishing legacy are at risk from the impacts of ocean acidification. The condition is destined to become much worse if nothing is done to curb the use of carbon-based fuels. (Learn More)

“The increasing acidification of Alaska waters could have a destructive effect on
all of our commercial fisheries. This is a problem that we have to think about in terms of the next decade
instead of the next century.” (Dr. Jeremy Mathis UAF School of Fisheries and Ocean Sciences)

This Alaska Fisheries website is committed to informing fishermen and all coastal Alaskans. Here, you will find a wealth of information about the science and effects of ocean acidification, special events, and ways you can help.
