Climate Change Oceans: Acid vs. Life OPENS May 26, 2018

Ocean acidification has been described as potentially the greatest environmental threat we face, yet very few people have even heard of it. The oceans have experienced a 30% increase in acidity in recent years. We're already seeing the impacts far and wide: it's changing fish behavior, making them more vulnerable to predation; it's harming coral reefs, the most biologically diverse areas of the sea; it's upsetting the ecological balance of the seas, and the world's oceans are rapidly becoming even more acidic. Visitors learn about acidification at live-action and computer animated video stations as well as several activity stations. 

We're open LATE on third Thursdays this summer!

On June 21, July 19 and August 16, Gateway is open until 9pm with evening activities and food trucks.

Summer Exhibits are ALL NEW!

Summer exhibits begin Saturday, May 26, 2018 at noon and run through Sep. 9, 2018.
