The dataset contains temperature, salinity, oxygen saturation and turbidity data from the Helgoland MarGate underwater observatory from the year 2015 in a temporal resolution of 1 hour. The cabled observatory is located in 10m water depth and comprises single or multiple sensors for a specific parameter (see https://www.awi.de/en/science/biosciences/shelf-sea-system-ecology/main-research-focus/cosyna/underwater-node-helgoland.html).
