Temperature anomalies in the Polaris hydrothermal plume, Gakkel Ridge

This dataset contains temperature anomalies measured in the Polaris hydrothermal plume on the ultraslow-spreading Gakkel Ridge, Arctic Ocean. The samples were collected during R/V Polarstern Expedition PS101. Temperatures were obtained via MAPRs (Miniature Autonomous Plume Recorders). Details on the analytical procedure and data processing can be found in Albers et al. (submitted).
