Ocean Acidification

Oyster industry under threat from acidic seawater - Ocean Action Agenda

Ocean Acidification is caused from excess carbon dioxide (CO2) in the atmosphere, due to global warming. The increase of CO2 is causing negative effects on many marine organisms, especially shellfish like Oysters. In this activity, students will use actual data used by researchers at the Deep Bay Marine Field Station to learn why low pH ocean water is harmful to shell formation, how to identify the different between healthy and 'acidified' shell growth, as well as discuss options to mitigate this issue into the future.

**This program can be run at either VIU Nanaimo Campus or Deep Bay Marine Field Station**
