A total of fifteen missions of the autonomous underwater vehicle (AUV) Abyss was performed in June 2016 over the TAG hydrothermal field as part of the EU-funded project Blue Mining. Each dive lasted a few hours and recorded information for a number of sensors including ADCP (RDI Teledyne Model WHN300 S/N), CTD (Seabird SBE49FastCAT), ECO (=combined fluorometer and turbidity senso; Wetlabs FLNTU/0712017), REDOX-sensor (Eh-sensor by Ko-Ichi Nakamura from AIST, South Korea) . The sensor data is recorded in separate files for each dive. The vehicles performance under water and core functions (roll, pitch, heading, power use, and many others) are recorded in the STATE file of each dive. Additionally magnetometer and passive electric field data is recorded for each dive.
