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.

Internationaler Artenschutz

Grundlage des internationalen Artenschutzes ist das Washingtoner Artenschutzübereinkommen von 1973, welches durch entsprechende Verordnungen in EU-Recht und damit auch in das bundesdeutsche Recht überführt wurde. Für die dort aufgeführten Arten gelten je nach Gefährdungsgrad besondere Vorschriften hinsichtlich Haltung, Vermarktung usw. Hierzu werden die geschützten Arten in Schutzkategorien (Anhänge A, B, C und D) eingeteilt. Welcher Schutzkategorie eine bestimmte Art zuzuordnen ist, können Sie auf einer Informationsseite des Bundesamtes für Naturschutz zum internationalen Artenschutz erfahren. In Deutschland wird das Washingtoner Artenschutzübereinkommen durch die Bundesartenschutzverordnung und das Bundesnaturschutzgesetz ergänzt. Dort werden weitere Arten als streng geschützt bzw. besonders geschützt eingeordnet. Für alle geschützten Arten gelten besondere Vorschriften bezüglich Erwerb, Haltung, Vermarktung usw. Für alle Fragen zum Artenschutz, beispielsweise Meldung geschützter Arten, Vermarktungsgenehmigungen, sonstige artenschutzrechtliche Genehmigungen, Beratungen zum Artenschutz usw. steht Ihnen im Landesamt für Umwelt- und Arbeitsschutz (LUA) ein „Team Artenschutz“ zur Verfügung.

Höheninformationen Sachsen

Digitale Höhenmodelle (DHM) beschreiben das Gebiet des Freistaates Sachsen durch dreidimensionale Koordinaten. Grundlage dafür bildet die klassifizierte Laserscan-Punktwolke (Höhengenauigkeit +/- 0,15 m), aus der die Bodenpunkte zu einem Digitalen Geländemodell (DGM, Bodenauflösung 1 x 1 m) bzw. zusätzlich die Nichtbodenpunkte (u. a. Vegetation, Gebäude) zu einem Digitalen Oberflächenmodell (DOM, Bodenauflösung 1 x 1 m) verrechnet werden. Die Abfrage der Gelände- und Oberflächenhöhe, der Höhendifferenz (wahre Objekthöhe, nDOM), der Geländeveränderung (Differenz zur vorherigen Datenerhebung) sowie der Hangneigung erfolgt über die Sachdatenabfrage (GetFeatureInfo, Höhenangabe im Höhenreferenzsystem DHHN2016, EPSG: 7837). Die Höhenlinien wurden aus dem Digitalen Geländemodell (DGM) automatisch abgeleitet, haben eine Äquidistanz von 2,5 Metern und sind nicht kartographisch aufbereitet. Aufgrund der kachelweisen Erzeugung kann es zu Linienunterbrechungen und leichten Versätzen kommen. Über die Kartenebene 'Beschriftung' können Ausdrucke mit einem beschrifteten Punktraster der Geländehöhe erzeugt werden. Verwenden Sie alle Kartenebenen (Layer) dieses Dienstes, setzen Sie die Kartenebenen in Ihrer Anwendung (Client) halbtransparent, um das Relief zu erkennen. Die Reliefdarstellung (Schummerung) mit Überhöhung ermöglicht die Erzeugung eines Kartenbildes mit 3D Effekt, wenn die darüberliegenden Fachdatenlayer halbtransparent angezeigt werden.

Field parameters and biochemical soil properties from NEP 1, NEP 2, NEP 3, Nördlingen, southern Germany

Soil physical-biogeochemical analyses were carried out on profiles NEP1, NEP2 and NEP3. Soil TC and TN were determined by CNS analysis, and total organic carbon (TOC) was determined by the difference between total inorganic carbon (TIC) and TC. Carbonate (CaCO₃) content was measured volumetrically using a Calcimeter and on air-dried, sieved (< 2 mm) and ground (ball mill) samples. The pH-values were measured on samples of profiles NEP1, NEP2, NEP3, which had less than 2% CaCO₃ content. Stable isotope ratios of δ¹³C and δ¹⁵N were analysed for the differentiation of C3 and C4 plants and the cultivation of legumes. The analyses were performed on air-dried, sieved (< 2mm) and ground (ball mill) samples. For ¹³C analysis, the soil samples were decarbonised with 10% HCl. In the field, separate samples were collected for the NEP1 and NEP2 profiles (28 samples in total) for analysis of urease activity and microbial biomass carbon (Cmic). Samples were stored at -18°C. Urease activity (enzyme analysis) is used to provide information on the input of urea and animal excrement. The mutual relationship between urease and Cmic was used to show and understand the past and present input of urea into the soil.

Environmental parameters, including dissolved organic carbon and molecular indices derived from ultra-high-resolution mass spectrometry (FT-ICR-MS) and infrared spectroscopy (ATR-FTIR)

We studied dissolved organic matter (DOM) dynamics in the sea surface microlayer (SML) during a multidisciplinary mesocosm study at the Sea sURface Facility (SURF) of the Institute for Chemistry and Biology of the Marine Environment (ICBM) in Wilhelmshaven, Germany (53.5148 °N, 8.1463 °E). The study was conducted from 18 May to 16 June 2023 as part of the BASS research unit (Biogeochemical processes and Air-sea exchange in the Sea-Surface microlayer). This dataset contains environmental data, including dissolved organic carbon (DOC), dissolved organic nitrogen (DON) and DOM molecular indices (MLBwL, Ibio, Iphoto, IDEG) calculated from ultrahigh-resolution mass spectrometry data (Fourier-transform ion cyclotron resonance mass spectrometer, FT-ICR-MS). Furthermore, we present attenuated total reflectance Fourier Transform Infrared (ATR-FTIR) data from representative samples for each bloom phase. General metadata from the multidisciplinary mesocosm study, including temperature, salinity and chlorophyll a, are provided in Bibi et al. on PANGAEA at the following link: doi:10.1594/PANGAEA.984101.

MOSES Sternfahrt-10, Elbe water distribution and dispersion of pollutants from the Elbe outflow into the Northern Sea (German Bight), 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, previously observed during the Elbe-Freshwater and Elbe-Tidal cruises, transported by the Elbe water into the North Sea. And second, on this occasion, the distribution of the Elbe water within the German Bight should be followed. To realize this, two drifter groups were deployed in the southern and, respectively, northern branch of the Elbe valley, which were continuously monitored by scientists at the Hereon institute. Further, the drifters were subsequently followed by three ships (RV Ludwig Prandtl, RV Littorina, RV Mya II), for in total three weeks, to measure hydrographic parameters multiple times along their journey. Additionally, to this stationary sampling, basic hydrographic parameters and dissolved methane were measured continuously along the tracks (content of the presented dataset). To ensure the comparability of the data from all three vessels a container was transferred from ship to ship. This "MOSES laboratory-container" was equipped with several sensors, amongst others a pocket FerryBox and a Greenhouse Gas Analyser (Los Gatos). The Ludwig Prandtl started the campaign on August 29th in Cuxhaven and deployed the drifters in the respective areas of the Elbe outflow section of the German Bight. Until the 1st of September the crew followed the drifters to sample this water body. Not all drifters could be reached every day, because it was too shallow, in this case the vessels occupied MOSES hydrographic stations from previous Sternfahrt cruises. On September 4th the vessel Littorina took over and started the second part of the campaign navigating from Cuxhaven to Heligoland covering as many drifter positions as possible. Until the 7th of September the crew sampled in the north eastern part of Heligoland up to Büsum. The handover of the container for the last episode of the cruise took place in Heligoland to the vessel Mya II. From there the crew navigated on September 12th towards west off the island Amrum. In the following days until September 14th, they sampled west off Heligoland to west off St. Peter-Ording. For more details about the exact tracks of the ships, have a look at the added map.

Geochemistry of sediments from Fehmarn Belt area, southern Baltic Sea during cruise EMB238

The geochemical composition of surface sediments and pore waters from the Fehmarn Belt area, southern Baltic Sea, was analyzed in the context of the establishment of exclusion areas for bottom trawling activity. Samples were taken on cruise EMB238 in May/June 2020 using a multi corer or benthic lander device. Besides on-site measurements, further dissolved major and trace elements, dissolved inorganic carbon, nutrients were analyzed in home laboratory. Results are complemented by the analysis of potential microbial gross sulfate reduction rates and the geochemical composition of CNS and extractable sulfur (AVS, CrS(II), and acid-extractable Fe, Zn, Pb, Fe, Mn contents.
