Ziel der Reise / Objectives of Cruise:
The transfer voyage ANT XXIX/1 between 27 October and 27 November 2012 from Bremerhaven to Cape Town marked the start of an exceptionally long research campaign on the southern hemisphere in the year of Polarstern`s thirty`s anniversary. The vessel will overwinter in Antarctica and return to its homeport Bremerhaven only after 1.5 years. The scientific activities during the transfer cruise also strongly differed from the standard programme. With the international EUROPA Summer School, they included a real premiere. For the first time, a big group of 27 international doctoral and master students under the supervision of 10 scientists and lecturers from 12 different universities and research institutions used Polarstern for an interdisciplinary training initiative. At 19 stations along the cruise track, data and samples were collected for an interdisciplinary research and education programme focussing on the "Pelagic Biodiversity of the Atlantic Ocean". Students had the unique opportunity to learn and apply state-of-the-art methods in marine research directly at sea for hands-on practical training. In the framework of the OCEANET programme, atmospheric measurements were conducted en route to provide a data basis and ground-truthing for climate models. Major focus of this project were the radiation balance at the Earth`s surface, the particle and aerosol composition in the atmosphere and cloud formation. Another project managed by DESY measured cosmic particles and their interactions with the Earth`s atmosphere. For this purpose, a new muon detector/neutron monitor for continuous measurements has been installed on Polarstern. In order to identify and confirm the breeding grounds of Antarctic baleen whales in the subtropical Atlantic Ocean, the deep-sea mooring AWI 247-1, deployed at 20?57.8`S 005?58.6`E off Namibia near the Walvis Ridge, was recovered and replaced. The mooring hosts a passive acoustic monitoring device, SonoVault, to verify the presence of large mysticete species on their proposed, yet largely unconfirmed, breeding grounds. Work onboard was completed by the installation, configuration and calibration of a series of scientific equipment intended for use during the following long Antarctic research campaign. This task included the calibration of the Hydrosweep multi-beam echosounder for bathymetry, the calibration of the EK60 multi-frequency echosounder for fisheries and zooplankton studies as well as the installation and test of new radiosonde equipment for weather balloons.
