| Abstract: |
The article focuses on the North South Atlantic Transect Ocean Capacity Exchange (NoSoAT | OceanCapX) expedition PS151, which served as an international training platform aboard the research vessel Polarstern to build capacity in oceanographic, meteorological, and climate observation techniques. The expedition involved 25 trainees rotating through five modules—Climate and Atmosphere, Oceanography, Observation Methods and Underway Sampling, Modelling, and Outreach and Philosophy—covering practical sampling methods (e.g., CTD rosette, Argo floats, XBTs), data analysis, climate modelling, and science communication. Key scientific activities included identifying major Atlantic water masses, measuring ocean heat content, analyzing phytoplankton communities, and studying air-sea gas exchange, with data to be archived in public repositories. The program also emphasized outreach through educational videoconferences, social media, and innovative approaches like the “Dance of the Carbon Cycles,” alongside philosophical reflections on human-ocean relationships, underscoring the expedition’s dual role in advancing ocean science and fostering global climate awareness.
