Windcube V2 measurements during Meteor cruise M208
No full textThe WindCube 2.0 vertical profiling lidar was placed on the ship to measure horizontal wind speed and direction profiles from 40m to about 300m. This pulsed Doppler lidar was continually measuring in DBS (Doppler-Beam-Swinging) mode, where 4 lines of sight measured each cardinal direction at a 28° angle to obtain the horizontal wind components, and a 5th line of sight measuring the vertical wind speed. The recordings of the lidar device are combined with those of a motion measurement setup, comprising an Inertial Measurement Unit (IMU) and a satellite compass that provide motion data in all six degrees of freedom. Motion data are applied to obtain the corrected wind profile data both on a 1-sec and 10-min level.
For the first part of the campaign, until early February 2024, the lidar was set up to measure at 12 levels up to 200m height. After that the maximum measurement height was adjusted to 290m.
The reported Carrier-to-Noise (CNR) level is used to control the quality the measurement, typically leading to a lower data availability at the top heights
Paleoenvironmental reconstructions from sediment core AMK-6150 (Norwegian Sea)
No full textThe data set contains paleoenvironmental reconstructions from core AMK-6150 (Norwegian Sea) that covers the last 2900 years. Paleoreconstructions include dinocyst-based summer and winter sea-surface salinity (SSS), temperature (SST) and sea-ice cover (SIC), sea-subsurface temperature (SSbT) based on planktic foraminifera and august sea-surface temperature (aSST) based on diatoms

Continuous water level observations at station BEFmate_I10low, 2020-01 to 2023-06
No full textData presented here were collected between 2020-01 and 2023-06 at station BEFmate_I10low within the research unit DynaCom (Spatial community ecology in highly dynamic landscapes: From island biogeography to metaecosystems, https://uol.de/dynacom/ ) involving the Universities of Oldenburg, Göttingen, and Münster, the iDiv Leipzig and the Nationalpark Niedersächsisches Wattenmeer. Experimental islands and saltmarsh enclosed plots were established in the back-barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog (Germany). Groundwater levels at different elevation zones were measured using pressure loggers deployed in dip wells within the experimental islands as well as in the saltmarsh enclosed plots. Measurements were obtained using Hobo U20L Water Level Loggers (Onset Computer Corporation, Bourne, MA/USA). All devices were pre-calibrated by the manufacturer. Logged data were retrieved in the field using a Hobo Underwater Shuttle (U-DTW-1) and were read out with the HOBOware Pro (V3.7.28) software, Subsequent data processing was done using MATLAB (R2024b). Atmospheric pressure correction for water-level calculations was applied using data from a nearby weather station. Post-processing and quality control included (a) the removal of data covering maintenance activities, (b) an outlier detection, and (c) visual checks. Outliers in water level and temperature time series were detected using a moving-median filter and a 3-sigma criterion, with additional cross-checking against a reference sensor. Identified outliers were removed, and height-corrected water level series were produced to ensure consistency across sensors and years

Radiosonde raw data measured during POLARSTERN cruise PS132, links to files
No full textThe meteorological observatory Polarstern continuously performs radiosoundings during times of ship operation. Typically, there is one launch to full altitude at 12 UTC every day. Additionally, there often is a launch with a smaller balloon for forecasting purposes (helicopter operations) around 6 UTC. All data published here is left "as recorded", no quality control was applied
