Ziel der Reise / Objectives of Cruise:

PS120:The transit cruise from Stanley (Falklands) via Las Palmas to Bremerhaven set out on the 02.06.2018 and ended in Bremerhaven on the 29.06.2019. The cruise was foremost dedicated to the training of students and the preparation and testing of on-board equipment for the upcoming MOSAIC project. During a "floating summer school" an international group of 23 students from 23 countries was trained in basic techniques of oceanography and remote sensing on a North-South transect from Port Stanley to Bremerhaven (South North Atlantic Training; SoNoAT). The participants learned how to take samples, how to process them and deal with the accompanying data. The main water masses between the Atlantic and the North Sea were characterized in terms of their hydrographic features down to a depth of approx. 500 m and more. A further focus during the transit cruise were physical and chemical measurements as well as detection of micro plastics and eDNA. In addition, the students got an introduction into the physics of the climate system, international climate negotiations and data analyses. Prior to the shipboard training a three day land-based workshop was held to prepare the scholars in application and usage of programming tools and methods. The floating summer school was a joint project between the Alfred Wegener Institute Helmholtz-Centre for Polar- and Marine Research, the POGO Centre of Excellence, ATLANTOS and the OCEAN TRAINING PORTAL (OTP). It was funded by the Nippon Foundation / POGO Centre of Excellence and the OTP and supported by REKLIM and PORTWIMS (Portugal Twinning for innovation and excellence in marine science and Earth observation). In preparation for the following MOSAIC expeditions sensors were re-calibrated and configured to fit into the board systems. This assured the functionality during the following MOSAIC programme, the scholar were involved in the sensor testing as well. The Polarstern arrived in Bremerhaven on 28.06.2019 and the expedition PS120 ended with a mini symposium on the projects carried out on board for interested public in the evening of the 29.06.2019.
