Geochemical parameters in peat depth profiles from ombrotrophic bogs in North and Central Europe. Drebbersches Moor, Germany

This dataset contains geochemical variables measured in six depth profiles from ombrotrophic peatlands in North and Central Europe. Peat cores were taken during the spring and summer of 2022 from Amtsvenn (AV1), Germany; Drebbersches Moor (DM1), Germany; Fochteloër Veen (FV1), the Netherlands; Bagno Kusowo (KR1), Poland; Pichlmaier Moor (PI1), Austria and Pürgschachen Moor (PM1), Austria. The cores AV1, DM1 and KR1 were taken using a Wardenaar sampler (Royal Eijkelkamp, Giesbeek, the Netherlands) and had diameter of 10 cm. The cores FV1, PM1 and PI1 had an 8 cm diameter and were obtained using an Instorf sampler (Royal Eijkelkamp, Giesbeek, the Netherlands). The cores FV1, DM1 and KR1 were 100 cm, core AV1 was 95 cm, core PI1 was 85 cm and core PM1 was 200 cm. The cores were subsampeled in 1 cm (AV1, DM1, KR1, FV1) and 2 cm (PI1, PM1) sections. The subsamples were milled after freeze drying in a ballmill using tungen carbide accesoires. X-Ray Fluorescence (WD-XRF; ZSX Primus II, Rigaku, Tokyo, Japan) was used to determine Al (μg g-1), As (μg g-1), Ba (μg g-1), Br (μg g-1), Ca (g g-1), Cl (μg g-1), Cr (μg g-1), Cu (μg g-1), Fe (g g-1), K (g g-1), Mg (μg g-1), Mn (μg g-1), Na (μg g-1), P (μg g-1), Pb (μg g-1), Rb (μg g-1), S (μg g-1), Si (μg g-1), Sr (μg g-1), Ti (μg g-1) and Zn (μg g-1). These data were processed and calibrated using the iloekxrf package (Teickner & Knorr, 2024) in R. C, N and their stable isotopes were determined using an elemental analyser linked to an isotope ratio mass spectrometer (EA-3000, Eurovector, Pavia, Italy & Nu Horizon, Nu Instruments, Wrexham, UK). C and N were given in units g g-1 and stable isotopes were given as δ13C and δ15N for stable isotopes of C and N, respectively. Raw data C, N and stable isotope data were calibrated with certified standard and blank effects were corrected with the ilokeirms package (Teickner & Knorr, 2024). Using Fourier Transform Mid-Infrared Spectroscopy (FT-MIR) (Agilent Cary 670 FTIR spectromter, Agilent Technologies, Santa Clara, Ca, USA) humification indices (HI) were determined. Spectra were recorded from 600 cm-1 to 4000 cm-1 with a resolution of 2 cm-1 and baselines corrected with the ir package (Teickner, 2025) to estimate relative peack heights. The HI (no unit) for each sample was calculated by taking the ratio of intensities at 1630 cm-1 to the intensities at 1090 cm-1. Bulk densities (g cm-3) were estimated from FT-MIR data (Teickner et al., in preparation).

Gebrauchsverhalten von Betonfahrbahnen mit Recyclingzuschlag

In enger Zusammenarbeit mit dem BMVBW und den Autobahnämtern der jeweiligen Bundesländer sollen alle wichtigen Daten bezüglich Herstellung und der dabei verwendeten Baustoffe von ein- und zweischichtigen Betonfahrbahndecken, bei denen RC-Betonzuschlag verwendet wurde, zusammengetragen und systematisch ausgewertet werden. Anschließend sollen die Betonfahrbahndecken augenscheinlich (Zustand der Oberflächen, Abwitterung bzw. Frost-Tausalz-Widerstand einschichtiger Decken, Dokumentation von Rissen, Fugenöffnungen und Unregelmäßigkeiten) in regelmäßigen Abständen untersucht werden. Um die in der Praxis auftretenden Verformungen (Aufwölben, Aufschüsseln) der Betonfahrbahndecken erfassen und mit Labormessungen vergleichen zu können, sollen orientierend Messungen mit einem am Baustoffinstitut entwickelten Lasermessgerät durchgeführt werden. In Laboruntersuchungen sollen darüber hinaus an Bohrkernen Materialkenndaten wie Feuchtigkeitsgehalt, Luftporengehalt und Verbundfestigkeit bestimmt werden.

Photosynthetic efficiency and symbiont cover of Amphistegina lobifera measured by PAM fluorometry and CLSM during a menthol-DCMU bleaching experiment (Nov–Dec 2022, Bremen, Germany)

This dataset contains experimental data from a one-month aquarium-based bleaching experiment conducted on Large Benthic Foraminifera (Amphistegina lobifera) from 16 November to 16 December 2022 at the Marine Experimental Facility of the Leibniz Centre for Tropical Marine Research (ZMT), Bremen, Germany. The aim of the experiment was to obtain symbiont-free A. lobifera individuals for future re-inoculation studies and symbiont switching experiments. The foraminifera were originally collected in May 2022 at the Interuniversity Institute for Marine Sciences (IUI) in Eilat, Israel (29°30'07.8N, 34°55'04.9E) and maintained in culture in Germany until the start of the experiment. To assess the effectiveness of two chemical agents—menthol and 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU)—in disrupting symbiosis, photosynthetic efficiency (measured as maximum quantum yield, Fv/Fm) was recorded every other day during the first week of the experiment using a Pulse-Amplitude-Modulated (PAM) fluorometer. Fv/Fm measurements were discontinued after the first week due to complete inhibition of photosynthesis. Symbiont coverage (%) was assessed on day one and then weekly until week four using Confocal Laser Scanning Microscopy (CLSM).

Aircraft measurements of single particle chemical composition over the Southern Baltic Sea during the BALTIC'15 campaign in 2015

During the BALTIC'15 campaign in August 2015 over the Southern Baltic Sea, measurements of chemical composition and vacuum-aerodynamic diameter of individual aerosol particles were conducted by the Aircraft-based laser ablation aerosol mass spectrometer (ALABAMA) operated by the Max Planck Institute for Chemistry (Particle Chemistry Department). Measurements were performed on board the Alfred Wegener Institute research aircraft Polar 5. Four research flights were conducted: - Scientific flight 1 (SF1) on August 26, 2015 - Scientific flight 2 (SF2) on August 28, 2015 - Scientific flight 3 (SF3) on August 28, 2015 - Scientific flight 5 (SF4) on August 30, 2015. The data set contains sampling time, location, identified particle types, and particle size (if available). For detailed information on data processing and particle type characterization, please refer to the publication by Zanatta et al. (2019) or contact the authors: Franziska Köllner (f.koellner@mpic.de) and Johannes Schneider (Johannes.schneider@mpic.de).
