Die BGR führte eine flächenhafte Befliegung im Raum Schleiz-Greiz (Thüringen) im Rahmen des BMBF-Verbundprojektes DESMEX durch. Es handelt sich hierbei um eine Vorerkundung mit dem geophysikalischen Standardmesssystem der BGR. Das Messgebiet liegt zwischen Gera und Plauen am Rande des Thüringischen Schiefergebirges an der Grenze zu und teilweise in Sachsen. Die Gebietsgröße beträgt etwa 445 km². 10 Messflüge mit einer Gesamtprofillänge von 1591 km (37.544 Messpunkte) wurden zur Abdeckung des gesamten Messgebiets benötigt. Der Sollabstand der 124 NW-SO-Messprofile beträgt 300 m, der Sollabstand der 8 NO-SW-Kontrollprofile beträgt 2000 m. Die ASCII-Datendatei beinhaltet die Rohdaten sowie die prozessierten HRD-Daten.
Die BGR führte eine flächenhafte Befliegung bei Gnarrenburg (Niedersachsen) im Rahmen des BGR-Projektes D-AERO-Moore durch. Es handelte sich hierbei um eine Studie zur Erkundung der Moore bei Gnarrenburg mit dem Aerogeophysik-Standardmesssystem der BGR. Das Moorgebiet liegt etwa 30 km nordöstlich von Bremen zwischen Bremervörde und Worpswede. Die Gebietsgröße beträgt etwa 173 km². 6 Messflüge mit einer Gesamtprofillänge von 778 km (20.789 Messpunkte) wurden zur Abdeckung des gesamten Messgebietes benötigt. Der Sollabstand der 62 WNW-OSO-Messprofile war 300 m, der Sollabstand der 6 NNO-SSW-Kontrollprofile lag bei 1500 m. Zusätzlich wurden 33 NNO-SSW-Profile mit 100 m Linienabstand in Detailgebieten geflogen. Die ASCII-Datendatei beinhaltet die Rohdaten sowie die prozessierten HRD-Daten.
A literature retrieval was performed for whole rock geochemical analyses of sedimentary, magmatic and metamorphic rocks in the catchment of River Thuringian Saale for the past 600 Ma. Considering availability and coincidence with paleontological an facies data the following indicators seem suitable to detect environmental and climatic changes: biogenic P for Paleoproductivity, STI Index for weathering intensity, Ni/Co-ratio for redox conditions, relative enrichments of Co, Ba and Rb versus crustal values for volcanic activity at varying differentiation. The Mg/Ca-ratio as proxy for salinity is applicable in evaporites. The binary plot Nb/Y versus Zr/TiO2 indicates a presently eroded volcanic level of the Bohemian Massif as catchment area for the Middle Bunter, whereas higly differentiated volcanics provided source material for Neoproterozoic greywackes. A positive Eu-anomaly is limited to the Lower Bunter and implies mafic source rocks perhaps formerly located in the Bohemian Massif.
The sampling area is located east (E-domain) and west (W-domain) of the Münchberg gneiss massif, NE Bavaria. Germany. Major and trace element compositions and Sr, Nd, and Pb isotope composition of a selected subset of Ordovician samples and post- Devonian samples of mafic igneous rocks are documented in the Table 1 'E-domain'.
Sr, Nd, and Pb isotope composition of selected mafic igneous rocks from the W-domain of Ordovicician, Silurian, and Devonian age are documented together with the previously analysed Rb-Sr, Sm-Nd, U-Th-Pb concentrations (Höhn et. al., 2018, doi:10.1007/s00531-017-1497-2) in the Table 2 'W-domain'.
To understand impacts of climate and land use changes on biodiversity and accompanying ecosystem stability and services at the Mt. Kilimanjaro, detailed understanding and description of the current biotic and abiotic controls on ecosystem C and nutrient fluxes are needed. Therefore, cycles of main nutrients and typomorph elements (C, N, P, K, Ca, Mg, S, Si) will be quantitatively described on pedon and stand level scale depending on climate (altitude gradient) and land use (natural vs. agricultural ecosystems). Total and available pools of the elements will be quantified in litter and soils for 6 dominant (agro)ecosystems and related to soil greenhouse gas emissions (CO2, N2O, CH4). 13C and 15N tracers will be used at small plots for exact quantification of C and N fluxes by decomposition of plant residues (SP7), mineralization, nitrification, denitrification and incorporation into soil organic matter pools with various stability. 13C compound-specific isotope analyses in microbial biomarkers (13C-PLFA) will evaluate the changes of key biota as dependent on climate and land use. Greenhouse gas (GHG) emissions and leaching losses of nutrients from the (agro)ecosystems and the increase of the losses by conversion of natural ecosystems to agriculture will be evaluated and linked with changing vegetation diversity (SP4), vegetation biomass (SP2), decomposers community (SP7) and plant functional traits (SP5). Nutrient pools, turnover and fluxes will be linked with water cycle (SP2), CO2 and H2O vegetation exchange (SP2) allowing to describe ecosystem specific nutrient and water characteristics including the derivation of full GHG balances. Based on 60 plots screening stand level scale biogeochemical models will be tested, adapted and applied for simulation of key ecosystem processes along climate (SP1) and land use gradients.
