Rohdaten BfG-GNSS-Messnetz

Das BfG-GNSS-Messnetzes besteht aus über 50 GNSS-Stationen im Bereich der Nord- und Ostsee. Primärer Zweck ist die Georeferenzierung von Pegeln der Wasserstraßen- und Schifffahrtsverwaltung (WSV). Die Rohdaten umfassen die kontinuierlichen Beobachtungsdaten der Satellitensysteme GPS, Glonass, Galileo und Beidou. Der Höhenunterschied 'dH1' zwischen dem jeweiligen Referenzpunkt der GNSS-Antenne und den zugehörigen Pegelfestpunkten (PFP) kann dem Sitelog der Permanentstation entnommen werden. Der Sollhöhenunterschied 'dH2' zwischen den Pegelfestpunkten und dem Pegelnullpunkt (PNP) wird durch das zuständige Wasserstraßen- und Schifffahrtsamt geführt.

Mg, Li, Sr and B/Ca in the calcareous red alga Lithothamnion corallioides

Data showing B/Ca, Mg/Ca, Li/Ca and Sr/Ca measured in the calcareous red alga Lithothamnion coralliodes lived-collected at different sites and depths across the Mediterranean Sea (Aegadian Islands, 40 m depth; Elba, 45 m depth; Pontian Islands, 66 m depth) and in the Atlantic Ocean (Morlaix Bay, 12 m depth). Element concentrations have been measured using an Agilent ICP-QQQ 8900 quadrupole ICP-MS coupled to an Excimer laser ablation system (193 nm wavelength), at 50 μm spots crossing the algal growth direction.

Compilation of high-resolution Holocene Mg/Ca and Uk37 SST reconstructions

This dataset contains the collection of published Uk'37, Uk37 and Mg/Ca records spanning the mid-to late Holocene and used in the analyses of Laepple&Huybers, EPSL 2014 and Laepple&Huybers, PNAS 2014. It is largely based on Leduc et al. (2010).

A global database of measured values of Li/Mg, Mg/Ca, Sr/Ca, Ba/Ca, U/Ca and Sr-U for coral and coralline algae paleoenvironment calibrations

Calcifying marine organisms provide a valuable means to access high-resolution historical records of the marine environment captured within their skeletal geochemistry. These records are essential for comprehending the effects of human-induced climate change and reducing uncertainties in future projections. Integrating investigations across various taxa, depths, and geographic locations can help identify universal environmental proxies and serve as a basis for targeted studies in the future. Here, we provide a comprehensive georeferenced database of measured values of Li/Mg, Mg/Ca, Sr/Ca, Ba/Ca, U/Ca and Sr-U in coral and coralline algae compiled from the scientific literature (1950-2021; http://www.webofknowledge.com, accessed 2022-09-30) for the purpose of interrogating and refining global, mineralogy specific and/or taxon-specific proxies for seawater temperature and barium. We include metadata relating to the source, timing and location of each study, the methodology used, and environmental and experimental information. The dataset presents an opportunity to quantify uncertainty and test the robustness of trace and minor element proxies for past environmental conditions, of which will be of value within the fields of geochemistry, ecology, climate, and palaeobiology. Full methodology and additional information provided in Williams et al. (2024).

FP4-ENV 2C, Peroxyradikal-Initiative fuer Umweltmessungen

Internationale Kooperation zur Entwicklung und Optimierung von Messverfahren zur Bestimmung der Peroxyradikalkonzentration in der Troposphaere. Einer der Schwerpunkte ist die Entwicklung eines flugfaehigen Messgeraets. Die neu entwickelten Geraete werden durch den Vergleich mit anderen Messverfahren und gemeinsamen Messkampagnen getestet und validiert.
