Soil moisture distribution at the Hordorf (Central Germany) groundtruthing site determined by mobile Cosmic Ray Neutron Sensing

Cosmic Ray neutron sensing (CRNS) is an emerging technology which is used to close the scaling gap between point measurements, such as TDR or soil samples, and the airborne remote sensing data. CRNS estimates the area-average soil water content by the detection of soil-reflected cosmic-ray neutrons in air. This method is characterized by an non-linearly shaped horizontal footprint of hundreds of meters and a vertical footprint of tens of centimetres (Köhli et al. 2015). During the campaign, a portable sensor (the so-called CRNS Rover) was used to study the spatial soil moisture variability in the target area in Hordorf. The rover was equipped with a CRNS-RV unit from Hydroinnova LLC (HI-RC01 detector) and a polyethylene shield below the detector to better reduce local effects of the field track. Neutron count data were processed including several physical, soil, and terrain corrections (see Schrön 2020, cfg file and the software <https://git.ufz.de/CRNS/cornish_pasdy>) to obtain the spatial soil moisture distribution at the Hordorf ground truthing site.

Pore water data of sediment incubation experiments under anoxic conditions

Enhanced mineral dissolution in the benthic environment is currently discussed as a potential technique for ocean alkalinity enhancement (OAE) to reduce atmospheric carbon dioxide (CO2) levels. This study explores how biogeochemical processes affect the dissolution of alkaline minerals in surface sediments during laboratory incubation experiments. These involved introducing dunite and calcite to organic-rich sediments from the Baltic Sea under controlled conditions in an anoxic to hypoxic environment. The sediment cores were incubated with Baltic Sea bottom water. Eight sediment cores were positioned vertically in a rack. Since the sediment surface was slightly oxidized by the bottom water (∼125 μmol l−1 upon recovery), the cores were left plugged on the top for 13 days to settle after recovery until the sediment surface was anoxic. To achieve chemical conditions that are expected in the natural system, 500l of retrieved sea water were degassed via bubbling with pure dinitrogen gas in batches of 100 l. Afterwards, between 50 and 60 l were transferred into an evacuated gas tight bag. After the transfer, pH and total alkalinity (TA) were measured to determine the dissolved inorganic carbon (DIC) of the water. Afterwards the DIC was increased via adding pure CO2 until a CO2 partial pressure (pCO2 ) of ∼2,300–∼3,300 μatm was established mimicking conditions prevailing in Boknis Eck during summer. Stirring heads were installed on the cores. To prevent the development of oxic conditions, it was ensured that as little gas phase as possible was left in the cores. Elimination of pelagic autotrophs, heterotrophs, and suspended particles was achieved by flushing the cores with modified bottom water for 2 days with a flow rate of 1.5 mml min−1. Afterwards, a continuous throughflow of 700 μl min−1 from the reservoir of modified bottom water was applied, leading to a residence time of ∼2.1 days inside the cores. For the experimental incubations, six cores received additions of alkaline materials, three with calcite (Cal1 - Cal3) and three cores with dunite (Dun1 - Dun3), leading to three replicates per treatment. Two control cores remained untreated (C1, C2). The amount of added substrate was based on the rain rate of particulate organic carbon observed in Boknis Eck (0.5 mmol cm−2 a−). The incubation lasted for 25 days. The volume of water in each core was determined at the end of the experiment via measuring the height of the water column after removing the stirring heads. At the end of the experiments, the bottom water was removed via suction and the cores were sliced for pore water analysis. The pore waters were recovered by centrifuging each respective sediment layer in 50 ml falcon tubes at 3000 rpm for 10 minutes. Afterwards, the supernatant water was transferred to polyethylene (PE) vials in an Ar-filled glove bag to minimize contact with oxygen. All samples were filtered through a 0.2 µm cellulose membrane filter and refrigerated in 25 ml ZinsserTM scintillation vials. TA samples (1 ml) were titrated with 0.02N HCl. For H2S, an aliquot of pore water was diluted. A 5 ml aliquot was frozen directly after the sampling procedure for later nutrient analysis. Nutrient measurements were performed either via manual photometric measurement (NH4) or using a Seal – AnalyticalTM QuAAtro autoanalyzer (PO43-). Samples for TA were analyzed directly after sampling by titration of 1 ml of bottom/pore water with 0.02N HCl. Titration was ended when a stable purple color appeared. During titration, the sample was degassed by continuous bubbling with nitrogen to remove any generated CO2 and H2S. The acid was standardized using an IAPSO seawater standard. Acidified sub-samples (30 μl suprapure HNO3- + 3 ml sample) were prepared for analyses of major and trace elements (Si, Na, K, Li, B, Mg, Ca, Sr, Mn, Ni and Fe) by inductively coupled plasma optical emission spectroscopy (ICP-OES, Varian 720-ES). For H2S, an aliquot of pore water was diluted with appropriate amounts of oxygen-free artificial seawater and the H2S was fixed by immediate addition of zinc acetate gelatin solution

Die Mitsubishi Chemical Advanced Materials GmbH stellt in Vreden (Nordrhein-Westfalen) thermoplastische Werkstoffe unter anderem für die Medizintechnik her. Sie ist eine Tochter des japanischen Konzerns „Mitsubishi Chemical Corporation“. Das Unternehmen stellt dabei unter anderem medizintechnische Produkte aus Polyethylen her. Beim bisher üblichen Herstellungsverfahren für diese Produkte kommt es in der Fertigung zu erheblichem Nachbearbeitungsbedarf und damit zu hohen Produktionsabfällen. In dem von der Mitsubishi Chemical Advanced Materials GmbH am Standort Vreden geplanten Hochtechnologiezentrum soll erstmalig in Deutschland die Produktion dieser medizintechnischen Teile mittels einer neu entwickelten Extrusionsanlage erfolgen. Diese innovative Verfahrenstechnik steigert die Ressourceneffizienz in der Produktion erheblich. Die aufwändige Nachbearbeitung entfällt. Weiterhin erlaubt das Verfahren erstmals die Verwertung von Produktionsabfällen, da diese direkt beim Hersteller anfallen. Schließlich zeichnet sich das neue Verfahren durch eine höhere Energieeffizienz aus, da eine Kühlung der Produktionsstücke bei der Extrusion entfällt. Der Energiebedarf sinkt von 6,7 Kilowattstunden pro Kilogramm Rohmaterial auf 4,4 Kilowattstunden pro Kilogramm Rohmaterial. Es kommt insgesamt zu einer Umweltentlastung von 400 Tonnen CO 2 pro Jahr.

Pore water data of laboratory incubation experiments on enhanced benthic weathering in organic rich Baltic Sea sediments

Enhanced mineral dissolution in the benthic environment is currently discussed as a potential technique for ocean alkalinity enhancement (OAE) to reduce atmospheric carbon dioxide (CO2) levels. This study explores how biogeochemical processes affect the dissolution of alkaline minerals in surface sediments during laboratory incubation experiments (January - May 2022). These involved introducing dunite and calcite to organic-rich sediments from the Baltic Sea under controlled conditions in an oxic environment. The sediment cores were incubated with Baltic Sea bottom water. Eight sediment cores were placed in a rack in an upright position. The bottom water was carefully removed via suction and replaced with a known volume (1.5 l – 2.0 l) of filtered (0.2 µm) Baltic Sea bottom water in order to remove pelagic auto- and heterotrophs and suspended particles. The volume of water added depended on the height of sediment in each core which varied slightly due to the recovery method. After this procedure, a gaseous headspace of ca. 10 cm was left in each core. Furthermore, the cores were equipped with adjustable stirring heads that contained ports for inserting optodes to continuously record pH and oxygen (O2) concentrations in the overlying water. In order to prevent anoxic conditions developing, ambient air was bubbled into the water column. The water column in each core was slowly and continuously flushed with a constant throughflow of 40 µl min-1 from a single reservoir of bottom water. The residence time of the water inside the cores was thus about 4 to 5 weeks. At the end of the experiments, the bottom water was removed via suction and the cores were sliced for pore water analysis. The pore waters were recovered by centrifuging each respective sediment layer in 50 ml falcon tubes at 3000 rpm for 10 minutes. Afterwards, the supernatant water was transferred to polyethylene (PE) vials in an Ar-filled glove bag to minimize contact with oxygen. Samples for TA were analyzed directly after sampling by titration of 1 ml of bottom/pore water with 0.02N HCl. Titration was ended when a stable purple color appeared. During titration, the sample was degassed by continuous bubbling with nitrogen to remove any generated CO2 and H2S. The acid was standardized using an IAPSO seawater standard. Anion element concentrations (SO42-, Cl-, Br-) were determined using ion chromatography (IC, METROHM 761 Compact, conductivity mode). Acidified sub-samples (30 μl suprapure HNO3- + 3 ml sample) were prepared for analyses of major and trace elements (Si, Na, K, Li, B, Mg, Ca, Sr, Mn, Ni and Fe) by inductively coupled plasma optical emission spectroscopy (ICP-OES, Varian 720-ES). In addition to the parameters listed above, pore waters were analyzed for sulfite (H2S) and Fe2+. For the analysis of dissolved Fe2+ concentrations, sub-samples of 1 ml were taken within the glove bag, immediately stabilized with ascorbic acid and analyzed within 30 minutes after complexation with 20 μl of Ferrozin. For H2S, an aliquot of pore water was diluted with appropriate amounts of oxygen-free artificial seawater and the H2S was fixed by immediate addition of zinc acetate gelatin solution.
