Sea Change Exhibit

Our new exhibit, Sea Change, will open in Fall 2021. The exhibit explores the work of Dr. Rosie Oakes-Grieve who is exploring how shelled ptreropods reveal ocean acidification. 

What are Pteropods?

Pteropods are tiny ocean snails. Affectionately known as the “potato chips of the sea,” pteropods help form the base of a massive ocean food web. Their thin, fragile shells are sensitive to changes in ocean chemistry, so Grieve is monitoring them to track the pace of climate change and its cascading effects on ocean life.  

Ocean Acidification and Climate Change

When we burn fossil fuels, we release gases including carbon dioxide (CO₂) into the atmosphere. Naturally occurring CO₂ plays an important role in the environment, but the massive amount of CO₂ we emit industrially and domestically is a major driver of climate change. Oceans absorb CO₂ like a sponge. This extra CO₂reacts with seawater and changes the chemistry of our oceans.  

What You Can Do

To tackle a global problem like climate change, we need to take collective action. Around the world, individuals and organizations like the Academy are working together on climate issues, and our efforts are gaining momentum.
