Raw Miniature Autonomous Plume recorder (MAPR) data from RV METEOR cruise M210@en

This dataset contains raw Miniature Autonomous Plume Recorder (MAPR) data for stations conducted during the cruise M210 in early 2025 in the Atlantic Ocean. The goal was to observe the extent of water masses emitted from the hydrothermal vent sites along the Mid-Atlantic Ridge, namely Rainbow and other satellite vents. The device measured temperature, pressure, nephelometric turbidity and oxidation reduction potential as well as associated device-specific parameters. The self-contained MAPR were mounted on the ships hydrowire on various heights above different instruments: a CTD Rosette (CTD), a trace-metal-free titanium rosette (TMR) and McLane in-situ pumps (ISP). One MAPR was also mounted directly to the frame of the ROV MARUM QUEST 5000 (ROV). Please note that the provided data are raw data. Decimal places are provided as they come out of the instrument, and do not reflect measurement accuracy. Additional handwritten deployment protocols and the original data files as they come out of the instrument are also provided.
