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.

Digitales Höhenmodell Hamburg Schummerungskarte / Geländerelief

Die Schummerungskarte ist eine in Graustufen abgeleitete 2D-Abbildung eines aus 3D-Daten (DGM1) erstellten Terrains für die Fläche der Freien und Hansestadt Hamburg (ohne das Gebiet des hamburgischen Wattenmeeres). Das Zusammenspiel der Geländehöhen und -neigungen kombiniert mit einer entfernten Lichtquelle lassen eine reliefartige Topografie entstehen, die ohne absolute Höhenwerte eine lebhafte Oberflächenstruktur visualisiert. In Bereichen von Bebauungen und Abschattungen (Brücken), dichte Vegetation, insbesondere Flächen in Wald- und Strauchgebieten, kann die generierte Oberflächenstruktur abweichen. Um diesen Effekt entgegenzuwirken wird die Darstellung mit den ALKIS-Gebäudegrundrissen überlagert.

ATKIS-DTK10 Sachsen-Anhalt

Topographische Karten sind landschaftsbeschreibende Karten, die die Erdoberfläche in ihren verschiedenen Erscheinungsformen -Siedlungen, Verkehrswege, Grenzen, Gewässer, Geländeformen und Vegetation- in Abhängigkeit des Kartenmaßstabes anschaulich, möglichst vollständig und übersichtlich wiedergeben. Signaturen und Kartenschrift helfen, die topographischen Objekte zu erläutern. Die Topographische Karte im Maßstab 1:10 000 wird mit dem Verfahren "Digital geführte Topographische Karte (ATKIS-DTK)" auf Grundlage des Digitalen Basis-Landschaftsmodells (Basis-DLM) hergestellt. Sie entspricht den deutschlandweit geltenden Vorgaben für den Karteninhalt, die geodätische Grundlage, den Zeichenschlüssel und das Layout. Die Aktualisierung erfolgt in periodischen Zyklen.

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.

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.
