RV Polaris - Ocean Acidification

For the last 14 years, in collaboration with the University of Otago's Chemistry Department, Dr Kim Currie has run a time series tracking ocean acidification. Every two months, she collects water samples along a 65-kilometre line from the tip of Otago Harbour out into subantarctic waters.
