Distribution and concentration of nutrients, carbon compounds and methane in water samples in the southern German Bight (North Sea) in September 2024 during the MOSES Sternfahrt 12

The 12th Sternfahrt of the ElbeXtreme and MOSES projects took place in 2024 from September 02 to 13, within the area of the German Bight (North Sea). Its objective was to get a more systematic grid of sampling data by spatially integrated onboard sensors. Therefore, the MOSES-laboratory container was installed again. Water samples were taken from the surface with a rosette or via Niskin bottles. The first part of the cruise was conducted by the research vessel (RV) Ludwig Prandtl, starting on the 2nd of September on Heligoland. From there, the crew navigated towards Cuxhaven covering some stations from previous MOSES cruises. For the next days, the ship followed a rectangular track, shifting northward each day, heading towards Heligoland again. Due to strong winds, the sampling stations were reduced to three on the last day. On Heligoland the RV Mya II took over the laboratory container and other sampling equipment for the second part of the cruise. Persistent strong winds delayed the start of the cruise until September 11. Since most of the planned stations were already covered from the RV Ludwig Prandtl, the crew decided to expand the sampling area using a more systematic zig-zag line. With the return of Mya II in the afternoon of the 13th September 2024, the campaign was successfully finished.

Remote sensing event campaign with various optical and thermal sensors for soil moisture and evapotranspiration derivation in Central Germany investigating possible effects of different spatial scales

The heat waves and droughts of 2018 / 2019 and in 2020 have had a devastating impact on the functioning of ecosystems and have led to an increasing vulnerability beyond the duration of heat waves (e.g. degradation and increased erosion, reduced carbon uptake by vegetation, modulated energy balance). Such impacts also include loss of agricultural production. A better understanding of the progression and the consequences of heatwaves and droughts is essential for the development and improvement of adaptation and protection measures. The airborne remote sensing event campaign performed in the agricultural area of the 'Magdeburger Boerde' in Central Germany aimed at providing remote sensing data sets from different platforms to derive high quality data for improving the understanding of influences and lag effects on hydrologic, biological/biogeochemical and atmospheric processes induced by the summer drought 2020. Multiple recurrences of drought periods in previous years may have led to irreversible changes in structure, composition and functioning of terrestrial ecosystems reducing ecosystem services and resilience. A second goal of the campaign with different available sensors in terms of an inter-calibration is to provide comprehensive and reliable data to ensure future campaign inter-comparability. The acquired data set includes airborne remote sensing data covering variable land cover types obtained by optical, thermal and multispectral sensors (see supplementary material: Schulz et al. (2020), Milewski et al. (2021) ). Furthermore, extensive data from various ground-truthing activities are available such as field spectrometer measurements, soil temperature mapping and soil moisture mapping via Cosmic Ray rovering and TDR-measurements. To complete the data set, micrometeorological time series, soil samples and vegetation characteristics were also taken.

Hydrographical time series data of Helgoland, Southern North Sea, since 2013

This dataset contains annual oceanographic observations collected at the Helgoland underwater observatory (54°11.594′ N, 07°52.762′ E; WGS84) from 2013 onwards. Measurements include water temperature, salinity, oxygen saturation, chlorophyll-a concentration, and turbidity. The observatory is located at a water depth of approximately 10 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 and sensor configuration are described in detail on the AWI COSYNA underwater observatory webpage. For comprehensive information on instrumentation, sensor deployment, calibration procedures, and data processing, please refer to the annual metadata documents entitled metadata_heluwobs_yyyy_hydrography.pdf associated with each yearly dataset.

Distribution of contaminants from the Elbe outflow into the North Sea (German Bight) based on water samples from the MOSES cruise Sternfahrt 10 in 2023

The Sternfahrt-10 of the MOSES campaign, from 29th August until the 15th of September 2023, had two objectives. One was to follow the dispersion of pollutants transported by the Elbe water into the North Sea, previously observed during the Elbe-Freshwater and Elbe-Tidal cruises. And second the distribution of the Elbe water within the German Bight. Therefore, drifter groups were deployed to follow individual water parcels. Those drifters were followed subsequently by three ships (RV Ludwig Prandtl, RV Littorina, RV Mya II), to extend the time period of measurements. Along the tracks, water samples were taken close to the drifters, alternatively at stations from previous cruises, resulting in 12 to 24 sampling points per week. In terms to detect the concentration of a variety of nutrients and carbon compounds from the south-eastern North Sea up to the island Amrum. Additionally, basic hydrographic parameters and greenhouse gases were sampled continuously throughout the whole cruise. Those results are not part of the present dataset, but can be found here, https://doi.org/10.1594/PANGAEA.971874. To ensure the comparability of the measured parameters a transportable container laboratory was passed from ship to ship always equipped with the same sensor systems. Just for specific water samples some special equipment was added. A map of the different tracks as well as information about the used sensors and data treatment, you can find in the additional material. For more detailed information about the MOSES Project and the cruise Sternfahrt-10, see the article cited in references.

In-situ soil moisture and -temperature time series measurements during SwabianMOSES campaign 2021

As part of the hydro-meteorological measurement campaign SwabianMOSES 2021 time-domain transmission soil moisture sensors and temperature sensors with custom-made logger systems were used to measure time series of these soil state variables. The aim of these investigations was to provide data on physical soil properties used in a cross-disciplinary approach for a better understanding of hydro-meteorological extremes (such as high precipitation events and droughts). Each measurement site consisted of sensors at three depths with two sensors each. Logger systems were installed at six different observation sites which were distributed across the whole campaign target area in the vicinity of the Swabian Jura in Germany. Decisions on the specific installation depths were made during the installation at the respective sites based on the constitution of the local soil profiles. Installation protocols with a brief soil profile description and photos are part of this dataset. The dataset contains the values of location and time (UTC), soil temperature (in °C), relative permittivity and soil moisture (in % vol) derived from permittivity. Determination of soil moisture was done using the formula of Topp et al. (1980). As sensors, the SMT100 soil moisture sensor with integrated temperature measurement were used. All sensors were installed within the upper 50cm below ground. The exact depths for each sensor are listed in the comments.
