Ziel der Reise / Objectives of Cruise:

The transit voyage of the 30th Antarctic Season will begin in Bremerhaven on October 25, 2014. The first cruise leg (PS88.1) will end in Las Palmas on November 2, 2014. During this cruise leg we will conduct an intensive training programme within the field of hydro acoustic measurements. Students from the international courses at the University of Bremen and at the Helmholtz Training Group POLMAR will participate. The transit to Las Palmas will also be used to test a newly installed device for synchronization of hydro acoustic units. The second leg of the 88th expedition will start in Las Palmas on November 2, 2014. During this leg the EK-60 system and a new Posidonia system will be tested and calibrated. The scientific work will concentrate on an oceanographic program. This work is part of the collaborative research center SFB754 ("Climate-Biogeochemistry Interactions in the Tropical Ocean"), the BMBF joint projects SACUS and RACE as well as the trilateral (Germany, France, NW Africa) project AWA. Steaming towards Cape Town, the deep-sea mooring AWI 247-1, deployed at 20?58.5'S 005?59.1'E, shall be recovered. The mooring hosts a passive acoustic monitoring device, SonoVault, to verify the presence of large Mysticetes species on their supposed, yet largely unconfirmed, breeding grounds. On the way from Bremerhaven to Cape Town (PS88. + PS88.2), two on-route measuring programs will be carried out: A survey of clouds, aerosol and water measurements (MPI-M, Hamburg) and measurements of galactic cosmic ray induced muons and neutrons (DESY, Zeuthen).
