Measuring pH in the Arctic Ocean: Colorimetric method or SeaFET?
Résumé
The suitability of the colorimetric method in a custom-made instrumental set-up and the commercial potentiometric SeaFET®electrode sensor to measure pH in surface oceanic water in the Arctic was investigated during the Chinese Arctic Research Expedition (CHINARE) in summer 2014. The instruments were set up in parallel on the on-board underway seawater supply for 65 days, enabling comparison in various conditions in the Arctic Ocean from the Chukchi Sea to the ice-covered high latitudes (81°N) and the open-water North-western Pacific Ocean. Overall, the instruments yielded pH datasets of similar high quality (method uncertainty ≤0.010
