Abstract:

Time-series data of physical oceanography and ocean current velocities were obtained from mooring AURORA1 on the Gakkel Ridge from July 2022 to July 2023 to record potential hydrothermal activities related to the Aurora vent field. The mooring was deployed during RV POLARSTERN expedition PS131 (ATWAICE) and recovered during PS137 (ALOIS). The attached archive contains raw data files of five Seabird SBE37 MicroCATs (nominal depths: 114m, 3065m, 3216m, 3367m, 3573m; sampling interval 10min/1h), and four AADI RCM11 current meters (nominal depths: 3064m, 3215m, 3366m, 3572m; sampling interval 2h). The mooring also included four sets of fouling plates and larvae samplers in collaboration with the Woods Hole Oceanographic Institution. Auxiliary information such as sensor calibration sheets, mooring diagrams, and schedule files are also provided, if applicable. The SBE37 MicroCAT at 114m (SN 7729) stopped logging in January 2023 due to low battery.

Comment:

The file AURORA1.zip includes all available sensor raw data from mooring AURORA1. The structure of the unzipped folders is mooring->sensor/sampler type->serial number->instrument files. All instruments were synched to UTC before deployment, and the offset after the recovery is supplied in the respective instrument folder, if available. The archive also contains the sensor calibration sheets/files and relevant sampler schedule files, if available. Finally, mooring schematics are also attached as pdfs in the root folder.

The authors are grateful to the captains, crews, and technical/scientific staff of the expeditions PS131 and PS137 onboard RV Polarstern. Many individuals have contributed to the conception of the research, the preparation of the instruments, the deployments and recoveries, as well as to the retrieval of the data, which we greatly appreciate. We acknowledge support from the Helmholtz infrastructure program "Frontiers in Arctic Marine Monitoring", and the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung.
