Pore-water pH, H2S, Cl-, SO42-, SiO2, NO2-, PO43-, NH4+, NO3-, major and trace element data from MUC cores taken during RV HEINCKE cruises HE575 and HE595 in the Helgoland Mud Area, German Bight

This dataset includes downcore measurements of pH values, H2S, Cl-, SO42-, SiO2, NO2-, PO43-, NH4+, NO3-, As, Ba, Ca, Cu, Fe, K, Li, Mg, Mn, Mo, P, Si and Sr concentrations for sediment cores retrieved using multi-corer sampling during RV Heincke expeditions HE575 and HE595 in 2021 and 2022, respectively. The samples were collected in the framework of the Project APOC (Anthropogenic impacts on particulate organic carbon cycling in the North Sea). All measurements were performed in the laboratories of the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, except pH values, which were determined onboard the research vessel.

GEMAS – Geochemische Kartierung der Acker- und Grünlandböden Europas, Originaldaten und DVD-Inhalt

GEMAS (Geochemical Mapping of Agricultural and Grazing Land Soil in Europe) ist ein Kooperationsprojekt zwischen der Expertengruppe „Geochemie“ der europäischen geologischen Dienste (EuroGeoSurveys) und Eurometeaux (Verbund der europäischen Metallindustrie). Insgesamt waren an der Durchführung des Projektes weltweit über 60 internationale Organisationen und Institutionen beteiligt. In den Jahren 2008 und 2009 wurden in 33 europäischen Ländern auf einer Fläche von 5 600 000 km2 insgesamt 2219 Ackerproben (Ackerlandböden, 0 – 20 cm, Ap-Proben) und 2127 Grünlandproben (Weidelandböden, 0 – 10 cm, Gr-Proben) entnommen. In den Proben wurden 52 Elemente im Königswasseraufschluss, 41 Elemente als Gesamtgehalte sowie TC und TOC bestimmt. Ergänzend wurde in den Ap-Proben zusätzlich 57 Elemente in der mobilen Metallionenfraktion (MMI®) sowie die Bleiisotopenverhältnisse untersucht. Alle analytischen Untersuchungen unterlagen einer strengen externen Qualitätssicherung. Damit liegt erstmals ein qualitätsgesicherter und harmonisierter geochemischer Datensatz für die europäischen Landwirtschaftsböden mit einer Belegungsdichte von einer Probe pro 2 500 km2 vor, der eine Darstellung der Elementgehalte und deren Bioverfügbarkeit im kontinentalen (europäischen) Maßstab ermöglicht. Zum Download werden die auf der dem Geol. Jb. B 102 beigefügten DVD abgelegten Originaldaten (*.xls & *.pdf, ca. 14 MB) sowie der komplette Inhalt der DVD (Daten, Karten & Grafiken, Statistiktabellen, …) in zwei Formaten (ISO-Image und kompletter Inhalt als ZIP-Datei, jeweils ca. 2 GB) angeboten.

Oxygen micro profiles of multi-corer sediment core HE595_12-3

This dataset includes onboard measurements of 100 μm vertical resolution oxygen micro-profiles from multi-corer cores retrieved during RV Heincke expeditions HE595 in 2022. Three to five measurements for each core were performed using micro-optodes with a tip diameter of 50 µm (OXR50, High Speed, Pyroscience). The samples were collected in the framework of the Project APOC (Anthropogenic impacts on particulate organic carbon cycling in the North Sea).
