Ziel der Reise / Objectives of Cruise:

The transit cruise started on 30.09.2022 in Bremerhaven and ended on 29.09.2022 in Cape Town. The cruise was dedicated to the training of NIPPON-POGO scholarship scholars. Prior to the shipboard training a five-day land-based workshop was held to prepare the scholars in application and usage of programming tools and methods while in quarantine. Aim of the training programme NoSoAT was to identify and characterize different water bodies along a North-South Atlantic transect, as part of training exercise for capacity building in oceanography. An international group of 13 students (mostly graduate level and doctoral candidates) was trained in basic oceanographic principles including seagoing methods and sampling associated with these, as well as bacterial and phytoplankton communities in water samples. The expedition track led via cross coastal, shelf and open Atlantic Ocean waters. Specifically, participants learned how to sample and analyse the ocean properties as "Ground Truth" information for Remote Sensing information and how to communicate scientific results to the general public and school kids. The survey participants were divided into groups of two or three, which rotated between the five main disciplines, which were Climate System, Oceanography, Modelling, Climate, Bathymetry and Microbiology (Fig.2.1:). Objectives of the floating summer school included: ? Differentiation of different water masses via temperature, salinity, turbidity etc. ? Localization of thermocline ? Detection of salinity gradients and turbidity ? Comparison of ground-truth data with remote sensing ? Measurements of atmospheric properties ? Studies of climate physics ? Discussion of the law of the sea and its impacts on in-situ marine observations As an additional task during the transit, chemical and physical measurements of the energy and mass exchange between ocean and atmosphere have been performed. Furthermore, the students got an introduction to the physics of the climate system, and the goals of the UN Ocean Decade. On the North South Atlantic Transect the scholars got insights in marine sciences and conducted individual projects on the interactions between ocean, atmosphere and climate. They learned how to translate knowledge in practice on board for example by feeding the Instagram account of the NF-POGO Centre of Excellence for Observational Oceanography as well as the miniboat project in the frame of Educational Passages. Pupils from Ireland, Spain, South Africa and Germany out together little boats equipped with GPS and temperature sensors which have been deployed from Polarstern by scholars. Per videoconference they presented the preparation and the deployment to the pupils and discussed the role of the oceans with them. Experiences from the cruise and awareness on the ocean and climate change could be transported directly to the class rooms. The sustainability days on Sylt were a good opportunity to report live from board and contribute with a presentation by Profs. Lemke and Wilshire. The training programme was a joint project between the Alfred Wegener Institute, the Max Planck Institute for Marine Microbiology in Bremen (MPI Bremen), the Partnership for Observation of the Global Oceans (POGO) and Educational Passages. The summer school was funded by the Nippon Foundation / POGO Centre of Excellence and supported by REKLIM (Helmholtz Network on Regional Climate Change and Humans). It is listed as an activity of the UN Ocean Decade. The Polarstern arrived in Cape Town on 29th of September 2022 and the expedition PS132 ended.
