Photos of marine litter in the shallow seafloor of the southernmost North and Baltic seas during the Walther Herwig III cruise WH462 in 2022

The dataset is a set of photos of marine litter at the seafloor and corresponding coordinates. The photos were taken in the southernmost North and Baltic seas, between 30.11.2022 and 12.12.2022 during the Walther Herwig III 462 research cruise (Date begin: 29.11.2022 - Date end: 14.12.2022, harbor begin: Bremerhaven - harbor end: Bremerhaven) . The video system used consists of a GoPro HERO 9 black in an aluminium case mounted in the front of the sledge and two lights with a total of 7200 lumen. Three laser pointers mounted in an equilateral triangle (laser center point distance 25.5 cm) provided the size reference for the video observation. The photos were taken as part of a study to visually quantify the amount of marine letter in the seafloor and compare this value with bottom trawl data.

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.

KI-Ableitung der Straßenbreiten im Stadtgebiet Freiburg

Dieser Datensatz enthält die Straßenbreiten im Freiburger Stadtgebiet, von Bordsteinunterkante zu Bordsteinunterkante, dargestellt als Breitenlinien. Die Straßenbreiten wurden aus den 3D-Punktwolken der Befahrung des Frühjahr 2024 automatisiert abgeleitet, indem die Unterkante der Bordsteine auf beiden Straßenseite identifiziert und lokalisiert wurden. An den Stellen, an denen auf einer oder beiden Seiten der Bordstein nicht identifiziert werden konnte, erfolgte keine Breitebestimmung. Die automatisierte Ableitung wurde nicht manuell nachgearbeitet. Bei groben Verschmutzungen am Fahrbahnrand, Bordsteinabsenkungen, ggf. parkenden Autos und verschiedenem "Straßenmobiliar" (z.B. Poller) kann es daher sein, dass ein "falscher Bordstein" identifiziert wurde und es daher zu einer fehlerhaften Breitebestimmung kam. Wir empfehlen daher die gleichzeitige Einblendung von Luftbildern um eine schnelle Einordnung der Bestimmung vorzunehmen.

INSPIRE: German Borehole Locations - Schleswig Holstein (GBL)

The GBL (INSPIRE) represents mechanically drilled boreholes approved by the State Geological Surveys of Germany (SGS). Most of the drilling data were not collected by the SGS, but were transmitted to SGS by third parties in accordance with legal requirements. Therefore, the SGS can accept no responsibility for the accuracy of the information. According to the Data Specification on Geology (D2.8.II.4_v3.0) the boreholes of each federal state are stored in one INSPIRE-compliant GML file. The GML file together with a Readme.txt file is provided in ZIP format (e.g. GBL-INSPIRE_Lower_Saxony. zip). The Readme.txt file (German/English) contains detailed information on the GML file content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements.

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

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).

Deutscher Bohrungsnachweis (WMS)

Der Deutsche Bohrungsnachweis (German Borehole Locations - GBL) bietet Zugriff auf alle freigegebenen Bohrdaten in der Bundesrepublik Deutschland, die von den Staatlichen Geologischen Diensten der Bundesländer (SGD) bereitgestellt werden. In Deutschland sind die SGD für die Speicherung, Verarbeitung und Weitergabe der Informationen über Bohrungen zuständig. Im Rahmen eines Gemeinschaftsprojektes werden die Bohrdaten in generalisierter Form über das Austauschformat BoreholeML bei der BGR zentral zusammengeführt. Der aufsetzende Dienst bietet Zugriff auf die übermittelten Stammdaten der Bohrungen aus den beteiligten Ländern. Die ersten beiden aggregierten Übersichtslayer zeigen die Bohrungsdichteverteilung im definierten Raster in der Fläche, während die Einzellokationen erst im größeren Maßstabsbereich sichtbar und abfragbar sind. Die Informationen bilden auch eine wesentliche Datenquelle in der Bohrpunktkarte Deutschland https://boreholemap.bgr.de/

Digital elevation model (DEM 1) of the River Elbe floodplain between Schmilka and Geesthacht, Germany

This digital elevation model (DEM) describes the topography of the active floodplain of the middle reaches of River Elbe between the Czech-German border near Schmilka and the weir in Geesthacht with 1 m spatial resolution in coordinate reference system "ETRS 1989 UTM Zone 33 N" and 0.01 m resolution in the German height reference system "Deutsches Haupthöhennetz 1992 (DHHN92)". The dataset was generated through aerial laser scanning (ALS) for terrestrial parts of the floodplain between April 2003 and December 2006 and echo sounding for aquatic parts of the central water course by the local waterway and navigation authorities (WSV) throughout the year 2006. Parts not covered by any of the two data collection methods were filled through linear interpolation. A comparison between DEM and 7476 height reference points confirmed a high accuracy with a mean deviation of elevations of ± 5 cm. Depending on the data source 95% of all checked points show a vertical deviation of less than 15 cm to 50 cm. A small section of the model was updated later to incorporate the dike relocation area Lenzen which became connected to the floodplain in 2011 so that the dataset describes the state of 2011. Since the dataset has a large volume it was split into 49 tiles.
