Ziel der Reise / Objectives of Cruise:

Objectives Bringing the new research vessel SONNE into service asked for an extended test phase trying to use all available scientific equipment of the ship and a selection of external large scientific gear. For this reason, it was planned to deploy ROV (remotely operated vehicle) KIEL 6000 (with a system weight of approx. 68 tons) off the SONNE during Test Cruise 7 in December 2014. The ship was scheduled to leave Kiel harbor on December 2nd, 2014. In advance of sailing, a period of 4 days was allowed for loading the ship and setting up the ROV system on deck. Loading turned out to be time-consuming as additional gear was brought on board which will be used during a number of scientific expeditions within the next year. Loading started after a public relation tour of the ship presenting the newly built vessel to the public. Cruise Narrative Loading started on Saturday 29th of November 2014 in Kiel. A network of container lifts had to be organized, also using two mobile cranes due to the heavy weight of some of the containers. Three containers had to be unloaded and 9 containers were to come on deck, partially to be moved after unloading. The following Sunday and Monday were used to set up the ROV KIEL 6000 system but also to fixate the Launch and Recovery System (LARS) of AUV ABYSS on deck of the SONNE in preparation of the first scientific cruise SO237 following Test Cruise 7. Setup of the ROV system went smooth; it included mounting the LARS system onto the A-frame at first, the arrangement of the containers i.e. winch, control- and power-container, connection of the power supply and the ROV itself and finally powering up the whole system. The SONNE left Kiel harbor on Tuesday morning, 2nd of December at 05:00 UTC heading into the Baltic Sea. At 07:00 several engine tests started which were finished at 13:00. At 14:00 we received two employees of DNV GL (De Norske Veritas Germanischer Lloyd, Certifing Agency) with the help of the small vessel POLARFUCHS to test and certify the ROV KIEL 6000 system. The tests were successfully finished at 16:00 and the DNVGL personnel left the SONNE at 16:10. Further propulsion tests started at 18:30. Early Wednesday morning the SONNE passed the Kiel locks and moored at the bunker pier. The bunkering lasted until 07:00 and the ship sailed at 07:30 from Kiel into the direction of the North Sea. The locks in Brunsbuettel were passed at 15:45 and we sailed from Brunsbuettel at 16:10, starting a long transit through the North Sea, the Channel, passing the Biscaya and the Iberian Peninsula to the first scheduled station, west of the Strait of Gibraltar. During the transit we deployed an APEX-float Saturday 06th on behalf of the German BSH at 08:32 UTC at 46?31'N and 08?16'W. On Monday 8th of December, we reached the first planned ROV deployment position between the continental Portuguese EEZ and the Portuguese-Madeira EEZ. First, we took a Multibeam record of the intended dive location and then positioned the ship. At 11:18, the deployment of ROV KIEL 6000 started and the vehicle descended 1050 m to the seafloor. Several tests and sampling exercises could be conducted at the seafloor and during ascent, a sampling system for pelagic animals could be successfully tested. At 16:27, the ROV was back on deck of the SONNE. Shortly after leaving the dive station, a second APEX Float was deployed at 17:18, position 36?10'N and 14?32'E. After the deployment, the transit to Las Palmas was continued. On Tuesday, 9th of December, wind and waves had increased and thus the planned second ROV dive had to be cancelled. Wednesday 10th the ship's crew used some time to start training on scientific gear permanently installed on the vessel, e.g. CTD rosette deployment system using a dummy weight, however, without sampling or touching the seafloor. After finishing these exercises, the transit to Las Palmas was continued. The SONNE berthed in Las Palmas on Thursday, December 11th
