In die Auswertung gehen dabei nur die Daten der ersten (von maximal drei) Lithologien einer geochemischen Gesteinseinheit ein. Für Informationen im Hinblick auf die Auswertung der Daten sowie auf die kartenmäßige Darstellung wird auf die Metadaten der digitalen Lithogeochemischen Karte 1:25 000 von Bayern (dLGK25) verwiesen.
We examined the growth response of a brackish snail (Hydrobiidae) against multiple temperature treatments in a mesocosm located beside the Alfred Wegener Institute Wadden Sea Station on Sylt (55°01′19.2″N, 8°26′17.7″E). Bulk sediments were collected south of Pellworm (54° 31' 55.83"N, 8° 42' 40.36"E) at low tide on March 22, 2022, transferred to mesh-lined crates and introduced to mesocosm tanks (170 cm × 85 cm × 1800 L). Experimental warming treatments were conducted using three heaters per tank (Titanium heater 500 W, Aqua Medic, Bissendorf, Germany). The full specifications for the mesocosms are already published (Pansch et al., 2016). Throughout the experimental warming period, four sampling events (March 30, April 25, May 24, June 20) were conducted to core sediments. Sediment cores were washed and sieved (1mm mesh size) to disaggregate infauna. Individuals were separated for the common hydrobiid mudsnail, which were subsequently imaged in groups on a typical petri plate under stereomicroscopy. A semi-automatic object segmentation and size measurement approach was developed to rapidly differentiate and measure individuals from images. Segmentation was highly accurate and precise against manual length measurements (end-to-end; mm) collected in ImageJ for 4595 snails. Scaling the segmentation method across the full dataset estimated >40,000 snails and presented a complex species-specific response to warming. The enclosed dataset represents all raw, processed, and segmented images (n= 3201) produced by this study.

The Nussloch Drilling Campaign (NUSS) involved drilling three loess sediment cores (85 mm in diameter) on April 21-25, 2019, on top of a loess hill at 49.31°N, 8.73°E, at an altitude of 215 m, close to the most recently described outcrop at the Nussloch reference site in Germany. Downhole logging was performed in the three drilling holes. Core S2, which has the most complete stratigraphy compared to previously published profiles, was analyzed using XRF core scanning. The name of the samples is given as NUSS for Nussloch, S2 for core S2, and C1-C11 for the subcore numbers. Depth is expressed in meters from the topsoil to the lowest level reached during drilling. The XRF data consists of the following elements: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Cu, Zn, Ni, Br, Rb, Sr, Zr, and Pb, in counts. These raw data counts are followed by the following ratios: Ca/Sr, Rb/Sr, Rb/K, Fe/Al, Fe/Mn, Si/Al, Ti/Al, Ti/Zr, Zr/Rb, and Ca/Al. Measurements were conducted every 1 cm from the top of the sub-cores. The measurements were performed with a resolution of 5mm on the AVAATECH Core Scanner at the EDYTEM laboratory in Chambéry in June 2015. This investigation aimed to conduct a comprehensive coring to acquire a sedimentary archive to ensure the preservation of this distinctive Nussloch record for future research projects.

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).

Oxbow lakes are continuous archives of flood events. On 28th June 2022 a 7.5 m long bottom sediment core (S1: 53.24758°N and 14.46271°E, 2.4 m b.s.l.) was collected from an oxbow lake in the Lower Odra Valley, NW Poland. Drilling was conducted using an Instorf sampler (Russian type; chamber dimension: 10 x 50 cm), onboard a "Manat" catamaran motorboat. After core recovery, each half-metre section was packed into a PVC tube and kept in cool rooms with a constant temperature. Samples were collected every 4 cm. For the first 2 m of the core grain-size, geochemical and Chironomidae analyses as well as radiocarbon dating were performed, which allow to identify flood events in the last 3200 years.
The elemental composition of samples from four sediment cores from the Mayschoß floodplain (Ahr river) was determined by X-ray fluorescence spectrometry (XRF). In the first step of preparation, large organic matter and pebbles were removed from freeze-dried samples (8 g) by sieving (2 mm). Subsequently, the samples were powdered and homogenised with vibratory Retsch mill MM 200. The uniform pills for the analysis were pressed with a carbon-based binding agent by Vaneox press at 20 t for 2 min. The elemental analysis of 50 elements was conducted in a He atmosphere using a Spectro Xepos energy dispersive XRF spectrometer. The surface elevation was extracted from Brell et al. (2023).
