Blog: Ocean acidification alters salmon’s sense of smell
A team of researchers from Washington state recently studied the effects of acidification on salmon’s sense of smell, also known as “olfaction,” which is particularly important for salmon to navigate back to their home streams to spawn. The scientists made the alarming discovery that at the pH levels of seawater predicted to occur in the next 50 to 100 years, salmon’s sense of smell may be significantly impaired.
