The Effects of Ocean Acidification on Pteropod Shells

2,102 views 2 months ago
This video shows the difference in swimming behavior and shell dissolution between a pteropod in seawater with low surface CO2 conditions and that of a pteropod exposed to elevated CO2 conditions.

A NOAA-led research team has found the first evidence that acidity of continental shelf waters off the West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon, mackerel, and herring, according to a paper published April 30, 2014 in Proceedings of the Royal Society B.

PMEL authors include Dr. Nina Bednarsek and Dr. Richard Feely.
