The MBL’s collecting boat, the Gemma, has had a few passengers from Woods Hole Oceanographic Institution of late: Aran Mooney, a biologist, and Casey Zakroff, an MIT-WHOI Joint Program graduate student. Mooney and Zakaroff are studying the impact of ocean acidification on squid, using data they collected with the help of the Gemma’s captain and crew. (Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere.)

Along with being a key species in the oceanic food web, squid have a multimillion-dollar impact on the human food industry. They are a vital component to the marine ecosystem’s wellbeing, as well as ours, making it crucial to monitor any risks that threaten healthy growth.

In the film, Is Ocean Acidification Affecting Squid?, produced by Daniel Cojanu, Mooney and Zakroff show how rising pH levels may be impacting a local and much prized marine species.
