This dataset contains Miniature Autonomous Plume Recorder (MAPR) data for stations conducted during the cruise PS137. Additionally it contains corresponding navigational data from the ships positioning system. The stations were executed in July 2023 to detect possible hydrothermal plumes at the Lucky B site where hydrothermal activity was suspected at approximately 81° latitude and -3° longitude. The self-contained MAPR were mounted on different deep-towed instruments to measure complementary data. 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.
