I drove up recently to work in the lab with my co-PI Dr. Brad Seibel at the University of Rhode Island. Our goal was to determine how long it would take to get 165 gallons of seawater to drop in pH by bubbling the seawater with pure carbon dioxide (CO2). Our goal was about a 0.4 drop in pH after 24 hours of bubbling. We reached our goal within 15 minutes! It was unexpected, but we now know we can manipulate pH rather quickly in large volumes of seawater for our experiments we will be running this field season in Antarctica.
