Benthic biogeochemistry data from RV HEINCKE cruise HE582 to the German Bight, North Sea in late summer 2021

This dataset contains data from the RV Heincke cruise HE582 to the German Bight of the North Sea in late summer 2021. The aim of the research was to investigate the source of sedimentary glycan concentrations in subtidal sandy sediments. Glycans represent a substantial fraction of extracellular polymeric substances and may affect flow dynamics in marine sandy sediments. The origin and concentration of glycans in sands remain understudied until today. To gain insights into oxygen supply and glycan concentrations in sandy sediment, we conducted in situ measurements and sampled sediment via a van Veen grab for ex situ investigations. Oxygen penetration depths were determined by a benthic lander, which was deployed for ca. 24h at each station. Chlorophyll a concentrations as an indicator for potentially photosynthetically active sedimentary biomass were derived via extraction with 90% acetone against Sigma Aldrich standards. Glycan concentrations served as indicator for extracellular polymeric substances and were quantified against a glucose standard curve via a phenol sulfuric acid assay after prior sequential glycan extraction (MilliQ, EDTA, NaOH). The final glycan concentrations are referred to per volume of porespace, and therefore given in mmol/l porewater. To investigate if benthic primary producers could be responsible for the extracted sedimentary glycan concentrations, we conducted stable isotope incubations.

Oxygen consumption rate, organic carbon and grain size data for intertidal sediments and oxygen concentration of pore waters data of Spiekeroog Island North Beach, May 2022 to April 2023

The permeable sandy sediments of beach aquifers receive a high input of electron acceptors, such as oxygen (O2), as well as fresh organic matter through seawater infiltration, driving the biogeochemical turnover in the subterranean estuary. Here, we experimentally determined seasonal sedimentary O2 consumption rates of intertidal sediments along a transect in the seawater infiltration zone at Spiekeroog Island North Beach, Germany, and present the data together with measurements of organic carbon and grain sizes, oxygen concentration of pore waters and beach topography. The samples were taken down to 1 m depth during two-monthly sampling campaigns from May 2022 to April 2023. Preliminary investigations of O2 consumption rates took place in in March, June and August 2017. Sediment and porewater sampling procedures were carried out as described by Massmann et al. (2023). O2 consumption rates were determined in slurry incubations of the retrieved sediments using gas tight vials (Labco Exetainer® 12 ml) equipped with O2 sensor spots (Pyroscience, OXSP5). Incubations were carried out in the dark at in situ temperatures, and vials were mounted on a rotating wheel to mimic porewater advection. The sediment's total organic carbon content was determined in a CS analyser (Eltra CS 800). Additionally, the fine fraction of the sediment was washed out and the organic carbon content of the fine sediments was measured in a CHNSO analyser (Hekatech Euro EA). The grain size distribution of the sediments was detemined using dynamic image analysis (Sympatec QICPIC). The O2 concentration in the pore water along the transect was measured immediately after the sample was taken using a flow-through oxygen optode (Pyroscience, OXFTC). The data was collected to investigate the impact of seasonal inputs and filtration efficiency on the O2 consumption during seawater infiltration into the permeable sands of beach aquifers.

Beach topography data of Spiekeroog Island North Beach, May 2022 to April 2023

Sandy beaches are highly dynamic land-ocean transition zones. For two-monthly sampling campaigns from May 2022 to April 2023, the beach topography along a sampling transect in the seawater infiltration zone at Spiekeroog Island North Beach, Germany, was obtained using Digital Elevation Models (DEMs) derived from aerial imagery during drone flights and manual Real-Time-Kinematic (RTK) differential GPS-surveys. In December 2022, the data was obtained using differential GPS measurements (Stonex S9 III Plus GNSS) because of unfavorable conditions for drone flights. These measurements were carried out in connection with sediment and pore water sampling along the transect during the campaigns. The data was collected to investigate the impact of morphodynamics on the O2 consumption during seawater infiltration into the permeable sands of beach aquifers.

Laser diffraction grain-size data of Late Glacial to present sediment cores from Schweriner See, NE Germany

This dataset contains laser diffraction grain-size distributions from five Late Glacial to present sediment cores recovered from the northern shore of Schweriner See (See = Lake, NE Germany). The cores (3.0–4.6 m long, 5 cm diameter) were collected using a percussion coring system from different geomorphological positions, including beach ridges, a lake terrace, and the base of a shore slope. One core (Döpe19/1) was obtained from the northeastern shore of Schweriner Außensee in the Döpe area, while four cores (HoVie05–HoVie08) were recovered from the Hohen Viecheln area in the north shore of Schweriner Außensee. Sediment cores were subsampled at 2 cm resolution, and grain-size measurements were performed using a Fritsch Laser Particle Sizer Analysette 22 MicroTec plus (0.08–2000 μm) following removal of organic matter and carbonates and ultrasonic dispersion.

Sediment characteristics in the muddy region in southeast of the island of Helgoland (North Sea)

Sediment were sampled on expedition HE625 of the R/V Heincke in July 2023 at 50 stations spread evenly over the muddy sediment region in southeast of the island of Helgoland (southeastern North Sea). At each station, two replicate samples were taken with a van Veen grab with a sampling area of 0.1 m² and a penetration depth of 10 cm. A subsample of the upper 6 cm of sediment was taken using a coring tube from the second grab with a diameter of 4.5 cm. The grain-size distribution was determined based on laser-diffraction granulometry using a CILAS 1180L particle size analyzer. Another sub-sample of 40 g of sediment were dried, weighed, and incinerated at 500 °C for five hours to estimate the organic content (%) as weight loss on combustion. Sediment variables included organic carbon content (OC), sediment composition (percentages of sand, silt, and clay), grain size (d10, d50, d90), and statistical measures of sediment grain size distribution (skewness, sorting, kurtosis).

Water content and loss-on-ignition data of Late Glacial to present sediment cores from Schweriner See, NE Germany

This dataset contains water content and loss-on-ignition data from five Late Glacial to present sediment cores recovered from the northern shore of Schweriner See (See = Lake, NE Germany). The cores (3.0–4.6 m long, 5 cm diameter) were collected using a percussion coring system from different geomorphological positions, including beach ridges, a lake terrace, and the base of a shore slope. One core (Döpe19/1) was obtained from the northeastern shore of Schweriner Außensee in the Döpe area, while four cores (HoVie05–HoVie08) were recovered from the Hohen Viecheln area in the north shore of Schweriner Außensee. The sediment cores were subsampled at 2 cm resolution. Water content and loss on ignition analyses were performed on 2–3 g of sediment placed in ceramic crucibles. Water content was determined after drying samples for 24 hours at 105 °C in a drying oven, while loss on ignition was calculated following combustion of organic matter for 4 hours at 550 °C in a muffle furnace.

Geologische Übersichtskarte der Bundesrepublik Deutschland 1:200.000 (GÜK200) - CC 4718 Kassel

Blatt Kassel bildet das Rheinische Schiefergebirge im Südwesten, das Münstersche Becken und seine begrenzenden Bergzüge im Westen, die Nordhessische Tertiärsenke am Südrand, die Buntsandsteinlandschaft des Sollings im Ostteil, die Bergzüge Hils und Sackwald im Nordosten ab. Mesozoische Sedimentgesteine dominieren das Blatt. Das Münstersche Becken ist mit Kalk- und Mergelsteinen der Oberkreide verfüllt. Im Randbereich (Teutoburger Wald und Eggegebirge) treten ältere Schichten der Trias bis Unterkreide zu Tage. Sie sind stark zerbrochen und zerstückelt, z. T. komplizieren Rutschmassen den geologischen Bau. Im Hinterland der Bergzüge, in östlicher Richtung, dominieren Sedimente der Trias (Buntsandstein, Muschelkalk, Keuper). Die Sand- und Tonsteine des Buntsandsteins im Solling, Reinhardswald oder Bramwald wurden flächenhaft in einem Festlandsbecken abgelagert, das große Teile Mitteleuropas bedeckte. Im Bereich der Nordhessischen Tertiärsenke, am Südrand des Kartenblattes, wird der Buntsandstein großflächig von quartären Lockersedimenten und Vulkaniten überdeckt. Endogene Kräfte führten im Tertiär zu einer Absenkung des Gebietes, zur Sedimentation teils mariner, teils festländischer Sande und Tone sowie zum Aufdringen basaltischer Magmen. In dem gesamten Gebiet sind Überlagerungen durch eiszeitliche Sedimente weit verbreitet (periglaziäre, glazifluviatile bzw. äolische Ablagerungen der Saale- und Weichsel-Kaltzeit). Größere Ausbisse von Jura und Kreide finden sich noch in der Nordost-Ecke des Kartenblattes. Hils und Sackwald zählen zu den mesozoischen Bergzügen, die den Südrand des Norddeutschen Tieflandes bilden. In beiden Fällen handelt es sich um eine Reliefumkehr, d. h. die ehemaligen Muldenstrukturen, gefüllt mit Jura- und Kreide-Sedimenten, stellen heute durch tektonische Vorgänge und Verwitterung herauspräparierte Höhenzüge dar. Die Ausläufer des Rheinischen Schiefergebirges im Südwest-Teil des Kartenblattes sind durch verfaltete und verschieferte Sedimentgesteine des Paläozoikums (Devon und Karbon) charakterisiert. Die devonischen Gesteine dominieren den zentralen Teil. Nach Norden und Süden schließen sich Sedimentgesteine des Karbons an. Im Osten bilden Ablagerungen des Zechsteins die randliche Begrenzung des Rheinischen Schiefergebirges. Neben der Legende, die über Alter, Genese und Petrographie der dargestellten Einheiten informiert, gewährt ein geologischer Schnitt Einblicke in den Aufbau des Untergrundes. Das Südwest-Nordost-verlaufende Profil beginnt im Massenkalk des Rheinischen Schiefergebirges, kreuzt randlich das Münstersche Kreidebecken und quert die Triasbedeckung inklusive Solling sowie Jura und Kreide von Hils und Sackwald.
