Ever wonder what the ocean might be like if it continues to become more acidic over the next 100 years? That’s the question that scientist Steve Archer is exploring at Bigelow Laboratory for Ocean Sciences. Archer is has conducted experiments in the Arctic and the tropics to determine effects of increasing ocean acidification on ocean life and conditions.  This summer, he will be conducting similar experiments at Bigelow Laboratory in huge containers, called mesocosms, where he can control environmental conditions, including the pH of the water.

The public is invited to come hear what Archer is finding, ask him questions, and engage in a lively discussion on Tuesday evening, from 6 to 7 p.m. at the Opera House at Boothbay Harbor, 86 Townsend Avenue in Boothbay Harbor. Archer’s presentation is the second in Bigelow Laboratory’s weekly summer “Café Scientifique” series. This year the focus is on ”Extreme Environments/Extreme Science.”

Café Scientifique is an international movement designed to encourage discussion about topical science issues between scientists and the public. There are more than 150 science cafés organized over 42 countries. All Café Scientifique events are open to the public free of charge, and members of the press are encouraged to attend.
