Abstract:
This dataset contains raw Miniature Autonomous Plume Recorder (MAPR) data for stations conducted during the cruise PS137 in summer 2023 at the Gakkel Ridge, Arctic Ocean. The goal was to observe the extent of water masses emitted from hydrothermal vent sites at different locations. 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 different instruments to measure complementary data to various underwater measurements such as CTD-rosettes, towed camera sledges or ROVs. 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.
