The expedition PS129 of the German research vessel Polarstern wanted to provide contributions to scientific projects encompassing physical oceanography, marine biology and marine chemistry, with the aim to investigate the water masses of the Weddell Sea and adjacent oceanic regions, and the ecological and chemical cycles within the regions. The expedition was another continuation of the long-term time series work in the framework of Hybrid Antarctic Float Observation System (HAFOS). The Polarstern departed from Cape Town, South Africa, on 3 March 2022, taking a route across the Southern Ocean to Antarctica and back, and ended on 28 April 2022 in Stanley, Falkland Islands.
