On the front lines of ocean acidification

Gretchen Hofmann is a professor at the University of California at Santa Barbara who has been working on the topic of ocean acidification for seven years. Most of Hofmann's work takes place in the polar environments of the Arctic and Antarctica. These areas are expected to be the first to experience acidification-related events because of their extremely cold ocean temperatures (-1.8°C) and naturally low carbonate saturation levels. Scientists expect that as early as 2040, the waters around the coast of Antarctica will not support calcification of the organisms now living there. Hofmann and her team recently returned from a field expedition, and she presented some of her findings at the recent meeting of the American Association for the Advancement of Science. Hofmann has two Antarctic research sites where MacGyver-inspired pH meters are continuously deployed to monitor th...
