Video transects were done using the A.IKANBILISTM hovering autonomous underwater vehicle (HAUV) of the company BeeX (https://beex.sg/a-ikanbilis/), which flew over the reefs along predefined transects at a depth of 0.5m above seabed and at a speed of 1 m s-1. From the dive videos of the HAUV, SBIs were extracted every 5 seconds. SBIs, each SBI features two parallel laser lines 25 cm away from each other. The camera used was a GoPro, the videos and pictures were taken perpendicularly to the seabed. The seabed images provide insights into the general composition of key species, higher systematic groups and ecological guilds. The images contain information on how benthic species are associated to each other. Transect files include individual images, whereas metadata of each image includes diving depth, date/time of transect. Geographical coordinates of some individual images is unavailable, images have a resolution of 300dpi and a size of 7 to 13 MB.
We measured Sn, Fe and Hg content as well as grain size composition of soil cores and streambed samples from the floodplain of the Röslau River (Bavaria, Germany), in order to reconstruct the floodplain development and chemical antropogenic impacts. The samples were collected in 2023 and analysed in 2023/24 using aqua regia digestion and ICP-OES/ICP-MS to analyse the elemental composition. To prepare the samples, the sediment was sieved (2 mm) to discard the gravel fraction and large organic pieces. Further homogenisation was undertaken by grinding the samples with a vibratory mill. Grain sizes were obtained using a combination of sieving and laser diffraction (Microtrac particle analyser; Microtrac Retsch GmbH SYNC SN 0233).
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).
Die biologischen Verfahren zur Abgasreinigung lassen sich in nasse und trockene Verfahren unterteilen. Das vorliegende Projekt beschaeftigt sich mit der trockenen biologischen Abgasreinigung. Das Ziel ist die Erprobung von herkoemmlichen Filtermedien, d.h. Gewebefilter aus Natur- und Kunstfasern fuer die Ansiedlung von Bakterien zu verwenden. Die Filtermedien werden von dem zu reinigenden Gas durchstroemt. Die darin befindlichen Schadstoffe, in ueberwiegendem Masse Geruchsstoffe, werden in die mit einer duennen Feuchtigkeitsschicht ueberzogenen Fasern uebertragen. An dieser Stelle werden sie sodann von den Mikroorganismen in unschaedliche Stoffe umgewandelt. Die Verwendung von Filtermedien zur biologischen Abgasreinigung eroeffnet diesem Verfahren neue Einsatzbereiche in Industrie und Gewerbe. Die bisher ueblichen Verfahren sind weitgehend auf die Landtechnik beschraenkt.
Ein Excimer-Laser schickt UV-Blitze aufs Wasser, Algen, Oele und Tracer antworten mit Fluoreszenzen, die mit einer Array-Kamera aufgenommen werden. Von Molen, Bruecken, Schiffen und Hubschraubern aus wurde der Fluoreszenz-Untergrund von Gewaessern und die Konzentrationen von Gelbstoffen, Algenpopulationen und Tracern gemessen. Im Labor wurden die Fluoreszenzen von Oelen in duennen Schichten und Emulsionen sowie Vergiftungserscheinungen an Algen untersucht.
Hydrologische Modelle können weder die Speicherung von Wasser in Oberflächengewässern noch den Flussabfluss, der unter anderem auch den Beitrag der kontinentalen Hydrologie zur Meeresspiegeländerung quantifiziert, ausreichend darstellen. Wir werden die neue Generation weltraumgestützter Satellitenaltimeter, zu denen die Delay-Doppler-, die Laser- und die bistatische SAR-Altimeter-Technik gehören, in das integrierte Monitoringsystem des SFB integrieren. Diese Beobachtungen sind dichter und genauer als herkömmliche Altimetermessungen, und sie werden es erlauben, die Auswirkungen von Wassernutzung und Klimawandels besser zu quantifizieren.
Grainsize data supports palaeoclimatic reconstruction of glacial/interglacial cycles for the Middle Pleistocene sediment record from the crater basin of Rodderberg, Germany. A sediment record measuring 72.8 m in length was retrieved by employing wire-line drilling techniques, utilising 3 m-long liners, from the silted-up crater basin of Rodderberg (East Eifel Volcanic Field) in the vicinity of the city of Bonn, Germany. For the purpose of grainsize analysis, the composite record ROD11 was systematically subsampled at a spatial resolution of 2 cm and examined through a laser diffraction particle size analyser (Beckman Coulter LS 13320). The resulting sedimentological data characterise glacials as silt-dominated (aeolian sediments: loess), interglacials as sand-dominated (runoff-related deposits from the step crater walls) and clay dominance for the Holocene soil. The terrestrial sediment record has been evaluated through multiple dating techniques and it provides a comprehensive environmental reconstruction since the Middle Pleistocene, thus providing valuable insights into the region's climate history.
