Long-term float-based observation of oxygen dynamics in major contrasting ocean regimes and biogeographical provinces

• Applicant: Professor Dr. Arne Körtzinger
• Subject Area: Oceanography
• Term: from 2011 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 194407323

The project is based on the cooperation with investigators of two famous research institutions and aims to contribute an oxygen observation component to the major field experiments with profiling floats which will be carried out by these institutions. These studies focus on the Arctic and Antarctic regions of the Atlantic, the subtropical gyres of Atlantic and Pacific, and the subpolar north Atlantic. Within this project optical oxygen sensor shall be installed on the existing floats of these studies. The oxygen observation component encompasses the entire chain from calibration of the oxygen sensor via processing and quality control of the oxygen data to full scientific evaluation and publication of the results. This will be carried out within a Ph.D. project with subsequent postdoc phase. The project is scientifically self-contained and at the same time contributes considerably to the interpretability and significance of all field studies. Besides the highly relevant scientific questions addressed the project also aims to provide a significant and internationally visible contribution to the development of autonomous biogeochemical observation methods in oceanography.
