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.

Gefahrstoffliste Bundeswehr. Analyse der chemischen Wirkung von Versorgungsartikeln

In einer netzwerkfaehigen, benutzerfreundlichen, menuegesteuerten Datenbank, die auf einem Personalcomputer (Betriebssystem MS-DOS) lauffaehig ist, werden Informationen zu Betriebsschutz (Arbeitssicherheit), Umweltschutz (einschl Abfallentsorgung) sowie Transport, Lagerung und Erste Hilfe gespeichert. Insbesondere werden Stoffeigenschaften, Sicherheitsmassnahmen fuer den Umgang und gesetzlich vorgeschriebene Kennzeichnungen angegeben. Diese Angaben beziehen sich zum einen auf reine Chemikalien und zum anderen auf Versorgungsartikel (Produkte, Zubereitungen) der Bundeswehr (zB Reinigungsmittel, Klebstoffe, Lacke etc ). Die Liste der Gefahrstoffe ermoeglicht es jeder Dienststelle, Betriebsanweisungen nach Paragraph 20 der Gefahrstoffverordnung (GefStoffV) zu erstellen. Die GefStoffLBw enthaelt derzeit Daten zu ca 900 reinen Stoffen und ca 2000 Versorgungsartikeln.

Between Path Dependence and Path Creation: The Impact of Farmers' Behavior and Policies on Structural Change in Agriculture

Farm structures are often characterized by regional heterogeneity, agglomeration effects, sub-optimal farm sizes and income disparities. The main objective of this study is to analyze whether this is a result of path dependent structural change, what the determinants of path dependence are, and how it may be overcome. The focus is on the German dairy sector which has been highly regulated and subsidized in the past and faces severe structural deficits. The future of this sector in the process of an ongoing liberalization will be analyzed by applying theoretical concepts of path dependence and path breaking. In these regards, key issues are the actual situation, technological and market trends as well as agricultural policies. The methodology will be based on a participative use of the agent-based model AgriPoliS and participatory laboratory experiments. On the one hand, AgriPoliS will be tested as a tool for stakeholder oriented analysis of mechanisms, trends and policy effects. This part aims to analyze whether and how path dependence of structural change can be overcome on a sector level. In a second part, AgriPoliS will be extended such that human players (farmers, students) can take over the role of agents in the model. This part aims to compare human agents with computer agents in order to overcome single farm path dependence.

Effects of water content, input of roots and dissolved organic matter and spatial inaccessibility on C turnover & determination of the spatial variability of subsoil properties

It is well established that reduced supply of fresh organic matter, interactions of organic matter with mineral phases and spatial inaccessibility affect C stocks in subsoils. However, quantitative information required for a better understanding of the contribution of each of the different processes to C sequestration in subsoils and for improvements of subsoil C models is scarce. The same is true for the main controlling factors of the decomposition rates of soil organic matter in subsoils. Moreover, information on spatial variabilities of different properties in the subsoil is rare. The few studies available which couple near and middle infrared spectroscopy (NIRS/MIRS) with geostatistical approaches indicate a potential for the creation of spatial maps which may show hot spots with increased biological activities in the soil profile and their effects on the distribution of C contents. Objectives are (i) to determine the mean residence time of subsoil C in different fractions by applying fractionation procedures in combination with 14C measurements; (ii) to study the effects of water content, input of 13C-labelled roots and dissolved organic matter and spatial inaccessibility on C turnover in an automatic microcosm system; (iii) to determine general soil properties and soil biological and chemical characteristics using NIRS and MIRS, and (iv) to extrapolate the measured and estimated soil properties to the vertical profiles by using different spatial interpolation techniques. For the NIRS/MIRS applications, sample pretreatment (air-dried vs. freeze-dried samples) and calibration procedures (a modified partial least square (MPLS) approach vs. a genetic algorithm coupled with MPLS or PLS) will be optimized. We hypothesize that the combined application of chemical fractionation in combination with 14C measurements and the results of the incubation experiments will give the pool sizes of passive, intermediate, labile and very labile C and N and the mean residence times of labile and very labile C and N. These results will make it possible to initialize the new quantitative model to be developed by subproject PC. Additionally, we hypothesize that the sample pretreatment 'freeze-drying' will be more useful for the estimation of soil biological characteristics than air-drying. The GA-MPLS and GA-PLS approaches are expected to give better estimates of the soil characteristics than the MPLS and PLS approaches. The spatial maps for the different subsoil characteristics in combination with the spatial maps of temperature and water contents will presumably enable us to explain the spatial heterogeneity of C contents.
