<Summary>This dataset contains annual oceanographic observations collected at the AWIPEV underwater observatory (78°54.200′ N, 11°54.000′ E; WGS84) from 2012 onwards. Measurements include water temperature, salinity, oxygen saturation, chlorophyll-a concentration, and turbidity. The observatory is located at a water depth of approximately 12 m (± tidal variation) and is equipped with one or more sensors for each measured parameter. Observations are recorded at an hourly temporal resolution. All data have undergone quality control using the four-step plausibility and quality assurance procedure described by Waldmann et al. (2022). The cabled observatory infrastructure comprises single or multiple sensors for each parameter and enables continuous long-term environmental monitoring in Kongsfjorden, Svalbard. For comprehensive information on instrumentation, sensor deployment, calibration procedures, data processing, and quality control, please refer to the annual metadata documents entitled metadata_svulobs_yyyy_hydrography.pdf associated with each yearly dataset. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.995222"!</Summary>
