Abstract:

Leg 1 of research expedition iMirabilis2 took place from 31st of July to the 30th of August 2021 (Las Palmas de Gran Canaria - Las Palmas de Gran Canaria) onboard RV Sarmiento de Gamboa. A particular focus was the characterisation of the Cadamosto Seamount. Current velocity data were acquired using a dual RDI Ocean Surveyor 75 kHz (Broadband and Narrowband) Vessel Acoustic Doppler Current Profiler (VADCP). The acquisition was made with the software VmDAS 1.46 and the processing with the CODAS (available at: https://currents.soest.hawaii.edu). The post-processing included a patch heading correction to eliminate gaps in the data and a watertrack calibration for both the phase and the amplitude.
