Seabed Images at pilot oyster reefs in the Borkum Reef Ground marine protected area taken in May 2024

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 second. Each SBI features two parallel laser lines 30 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 and time of individual images is unavailable, images have a resolution of 300dpi and a size of 9 to 13 MB.

Ecosystem functions of rare arable plants - field study: Araneae data

Partly taken from the materials and methods of https://doi.org/10.1016/j.baae.2022.12.003: To compare the activity densities of ground-dwelling predators between treatments with and without RAPs, spiders were sampled using pitfall traps, which were set up after each round of aphid counting (one per plot, twice per year; Brown & Matthews, 2016). The traps (with a volume of 400 ml and a width of 90 mm) were filled with a mixture of water and ethylene glycol (1:1; 120 ml) and dug at ground level into the middle of each plot. The traps were covered with a plastic roof and a metal grid (15 × 15 mm grid size) to avoid overflowing during rain and accidental rodent catches (Császár et al., 2018). The traps were activated for 7 days. Subsequently, all arthropods were transferred into 70% ethanol. Spiders were identified to species according to Nentwig et al. (2019). Spider hunting strategy (active hunter or web-builder) was used as the feeding trait according to Cardoso et al. (2011).

Ecosystem functions of rare arable plants - field experiment: Carabidae data

Partly taken from the materials and methods of https://doi.org/10.1016/j.baae.2022.12.003: To compare the activity densities of ground-dwelling predators between treatments with and without RAPs, carabids were sampled using pitfall traps, which were set up after each round of aphid counting (one per plot, twice per year; Brown & Matthews, 2016). The traps (with a volume of 400 ml and a width of 90 mm) were filled with a mixture of water and ethylene glycol (1:1; 120 ml) and dug at ground level into the middle of each plot. The traps were covered with a plastic roof and a metal grid (15 × 15 mm grid size) to avoid overflowing during rain and accidental rodent catches (Császár et al., 2018). The traps were activated for 7 days. Subsequently, all arthropods were transferred into 70% ethanol. Carabids were identified to species according to Hůrka (1996). Carabid feeding behavior was classified according to Homburg et al. (2014). To simplify the dataset, carabid feeding behavior was classified as predominantly granivorous (species mainly feed on seeds and fruits) or as carnivorous/omnivorous, because carnivorous and omnivorous species are potentially feeding on aphids and other non-plant material.

Iron, mercury and tin contents as well as grain sizes measurements from fluvial sediments of the Röslau River, Bavaria, Germany

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).

Entwicklung der Laserionisation bei Atmosphärendruck: APLI

In einer Zusammenarbeit der Physikalischen und Theoretischen Chemie und der Analytischen Chemie der BUW ist es 2005 gelungen, neben den etablierten Atmosphärendruck-Ionisationsverfahren ESI, APCI und APPI eine vierte AP Methode einzuführen, die auf der Laserionisation basiert (Atmospheric Pressure Laser Ionization, APLI). Das Verfahren hat ein sehr großes Potential im Bereich der Ultra-Spurenanalytik in der Gas- und Flüssigphase und findet zurzeit international größere Beachtung. Mit Hilfe der APLI werden völlig neue Ansätze in der Atmosphärendruck-Massenspektrometrie möglich. Diese sollen in den kommenden Jahren mit Nachdruck verfolgt werden. Die APLI Methode verbindet die Massenspektrometrie sowohl mit den chromatographischen Methoden HPLC, CE, als auch GC. Darüber hinaus kann sie direkt an Reaktoren gekoppelt werden, die bei Atmosphärendruck operieren und ist damit optimal für den Einsatz in atmosphärisch-chemischen Untersuchungen geeignet.

ATKIS - DGM1 (2016)

DGM1 - Laserscan-Geländemodell Im Frühjahr 2016 fand eine Airborne-Laserscan-Befliegung zur Generierung eines neuen hochgenauen Geländemodells für das gesamte Saarland statt. Dabei wurde die Geländeoberfläche mit einem im Flugzeug installierten Laser abgetastet. Als Resultat liegt seit Anfang des Jahres 2017 das hochgenaue DGM1 mit einer Rasterweite von 1m und einer durchschnittlichen Höhengenauigkeit von 1-2 dm vor. Als gewünschter Nebeneffekt wurden neben Geländedaten auch auf der Erdoberfläche befindliche Objekte wie Gebäude und Vegetation mit eingescannt, die als Oberflächendaten verfügbar sind. Digitale Geländemodelle (DGM) sind digitale, numerische, auf ein regelmäßiges Gitter reduzierte Modelle der Geländehöhen und –formen der Erdoberfläche. DGM können außerdem ergänzende Angaben (z.B. Geländekanten, Geripplinien, markante Geländepunkte) enthalten. Sie beinhalten keine Information über Bauwerke (z.B. Brücken) und Vegetation. Das DGM1 unterscheidet sich von den anderen DGM durch seine Höhengenauigkeit und seine Gitterweite.

Intercalibration of the intra-laboratory 40Ar/39Ar reference material Drachenfels sanidine

The dataset contains full 40Ar/39Ar geochronological data completed by multi-collector noble-gas mass spectrometry using the laser total fusion technique on sanidine separated from the Drachenfels trachyte (Drachenfels, Bad Godesberg, Germany). The Drachenfels sanidine represents a useful intra-laboratory reference material for laser work. The purpose of the dataset is to share updated intercalibration data for the intra-laboratory Drachenfels sanidine, relative to the widespread fluence monitors Alder Creek sanidine and Fish Canyon sanidine, that can be used in future 40Ar/39Ar geochronological studies. W. McIntosh (New Mexico Geochronology Research Laboratory, Socorro, NM), P. Renne (Berkeley Geochronology Center, Berkeley, CA) and J.R. Wijbrans (Vrije Universiteit Amsterdam, NL) kindly provided splits of FCs, ACs and DRA1, respectively. The Ar laserprobe facility was realized with the financial support of CNR. The CO2 laser system was acquired within the PNRR – Mission 4, “Education and Research” - Component 2, “From research to business” - Investment line 3.1, “Fund for the creation of an integrated system of research and innovation infrastructures” - Project IR0000025 MEET.

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.
