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.

该项目是在与两个著名研究机构的调查人员合作的基础上进行的，目的是为这两个机构将进行的用剖面浮标进行的重大实地实验提供一个氧气观测部分。这些研究的重点是大西洋的北极和南极地区、大西洋和太平洋的副热带环流以及北大西洋的副极地。在本项目中，光学氧传感器应安装在这些研究的现有浮子上。氧气观测组件涵盖了从氧气传感器的校准、氧气数据的处理和质量控制到全面的科学评估和结果发布的整个链条。这将在博士学位内进行。后续博士后阶段的项目。该项目在科学上自成一体，同时大大有助于所有实地研究的可解释性和意义。除了处理高度相关的科学问题外，该项目还旨在为发展海洋学中的自主生物地球化学观测方法作出重大和国际可见的贡献。
