Intertidal Ecosystems Photos & Multimedia
Ocean acidification is rapidly changing the chemistry of ocean water worldwide and making it more difficult for many organisms to build their shells and skeletons. This video explores how park staff at Point Reyes National Seashore are working with local scientists to better understand the effects of ocean acidification, specifically on shellfish and other marine organisms.

As the climate changes, many early signs will appear along our ocean shorelines. This twelve minute film takes you to Olympic National Park’s wild Pacific Coast and follows marine ecologist Dr. Steve Fradkin as he studies its rocky intertidal zone.
More than a hundred thousand marine species build their bodies using calcium carbonate. This incredible diversity of life evolved over millions of years, as animals figured out ways to pull calcium and carbonate ions from the water to build shells and skeletons. But all of this is changing. Our addiction to fossil fuels and the billions of tons of carbon dioxide we're pumping into the atmosphere each year may be undoing millions of years of evolution in a geological blink of time.
