| Summary: | A detailed CTD/LADCP survey in the Romanche Fracture Zone was carried out during cruise 62 of the R/V Akademik Ioffe in August, 2022. The main idea of this survey was to measure abyssal currents of Antarctic Bottom Water and estimate its transport to the East Atlantic. The stations were located in the middle part of the fracture zone at the entrance to the Vema Deep (the deepest depression in the fracture zone). In total, 23 full water depth stations (down to 5865 m) were performed in three channels of the sill between two neighboring deep basins of the Romanche Fracture Zone. The rosette system General Oceanics GO1018 included Idronaut Ocean Seven 320 plus Conductivity-Temperature-Depth (CTD) probe and Lowered Acoustic Doppler Current Profiler (LADCP; 300 kHz Teledyne RD Instruments WorkHorse Monitor with an external battery package). The velocity profiler was set in the narrowband mode, which increases the profiling range in comparison with the broadband mode and allows more reliable processing of the raw ... |
