The autonomous underwater vehicle (AUV) ABYSS from IFM-GEOMAR successfully completed its 50th dive last week during the Poseidon expedition P403 (PI: Prof. T. Kanzow).
During the dive, ABYSS took high-resolution bathymetric measurements of the well-known Lucky Strike hydrothermal field as well as oceanographic data with a new microstructure profiler, constructed by Rockland Scientific Inc. The data delivered by the profiler illustrates that the AUV is also an excellent platform to measure mixed processes in the water column. For this reason, the P403 expedition contributed to the further development of ABYSS as a multidisciplinary research platform.
During the 50 dives, ABYSS covered a distance of 2446 km in 453 hours altogether. During the expedition P403, which ended on August 30th, ABYSS completed 11 dives without any technical problems. The vehicle was used up wind force 6 and 3 metre high waves.
