Nachweis des Europäischen Waldelefanten Elephas antiquus (Falconer & Cautley, 1847) bei Neubrandenburg in Mecklenburg-Vorpommern (NE-Deutschland) - Fundbericht
(Neubrandenburger Geologische Beiträge; Band 11)
Funde von pleistozänen Großsäugern sind in Mecklenburg-Vorpommern (NE-Deutschland) wegen der starken Dominanz glazigener Sedimente mit ungünstigem Erhaltungspotential vergleichsweise selten (Benecke 2002, Meng et al. 2010). ... -
Nano-Magnetite Aggregates in Red Soil on Low Magnetic Bedrock, Their Changes During Source-Sink Transfer, and Implications for Paleoclimate Studies
; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Solid Earth, 2020)
Soil and lake sediments are important paleoclimate archives often forming a source-sink setting. To better understand magnetic properties in such settings, we studied red soil on low-magnetic bedrock and subrecent sediments ... -
Nano-Powdered Calcium Carbonate Reference Materials: Significant Progress for Microanalysis?
; Garbe-Schönberg, Dieter; Veter, Marina; Stoll, Brigitte; ; ; Lugli, Federico; Jentzen, Anna; ; Wassenburg, Jasper A.; Jacob, Dorrit E.; Haug, Gerald H. (Geostandards and Geoanalytical Research, 2019)
Homogeneity, mass fractions of about forty trace elements and Sr isotope composition of Ca carbonate reference materials (RMs) between original and nano-powdered pellets are compared. Our results using nanosecond and ... -
Nanoscale Imaging of High‐Field Magnetic Hysteresis in Meteoritic Metal Using X‐Ray Holography
; ; ; Hessing, P.; Eisebitt, S.; ; (Geochemistry, Geophysics, Geosystems, 2020-08-03)
Stable paleomagnetic information in meteoritic metal is carried by the “cloudy zone”: ~1–10 μm‐wide regions containing islands of ferromagnetic tetrataenite embedded in a paramagnetic antitaenite matrix. Due to their small ... -

NanoSIMS analysis and high resolution electron microscopy of silicate stardust grains from red giant stars and supernova explosions
(Univ. Frankfurt (Main), 2009)
This thesis deals with the analysis of presolar silicates and oxides by high resolution mass spectrometry and electron microscopy techniques. This stardust was identified by its extreme oxygen isotopic anomalies, which ... -
NanoSr – A New Carbonate Microanalytical Reference Material for In Situ Strontium Isotope Analysis
; Lugli, Federico; Hattendorf, Bodo; ; ; Guinoiseau, Damien; (Geostandards and Geoanalytical Research, 2019)
The in situ measurement of Sr isotopes in carbonates by MC-ICP-MS is limited by the availability of suitable microanalytical reference materials (RMs), which match the samples of interest. Whereas several well-characterised ... -

Natur erleben und Raum inszenieren
(Universtätsverlag Göttingen, 2008)Sowohl private als auch öffentliche Akteure widmen sich der Inszenierung von Naturerlebnisangeboten. Die Vielfalt an thematischen Inhalten, didaktischen Konzepten und Zielgruppen sorgt dafür, dass der Begriff Naturerleben’ ... -
Natural and anthropogenic compaction in North Germany (Schleswig-Holstein): Verification of harmful subsoil compactions
; ; ; ; (Soil Use and Management, 2020)
Many soil types in the federal state of Schleswig-Holstein (North Germany) are naturally compacted in the subsoil due to pedo- or geogenic processes (42% of the area) but, due to anthropogenic impacts, the percentage of ... -
Natural building stones of Mexico–Tenochtitlán: their use, weathering and rock properties at the Templo Mayor, Palace Heras Soto and the Metropolitan Cathedral
(Environmental Earth Sciences, 2011)In the Aztec period and in colonial times different natural stones originating in the Valley of Mexico were used for building construction. Stone weathering was investigated onsite at various historical buildings within ... -

Natural variability or anthropogenically-induced variation? Insights from 15 years of multidisciplinary observations at the arctic marine LTER site HAUSGARTEN
Soltwedel, Thomas; Bauerfeind, Eduard; Bergmann, Melanie;; Budaeva, Nataliya; Busch, Kathrin; Cherkasheva, Alexandra; ; Grzelak, Katarzyna; Hasemann, Christiane; Jacob, Marianne; Kraft, Angelina; Lalande, Catherine; Metfies, Katja; Nöthig, Eva-Maria; Meyer, Kirstin; Quéric, Nadia-Valérie; Schewe, Ingo; Włodarska-Kowalczuk, Maria; Klages, Michael (Ecological Indicators, 2016)
Time-series studies of arctic marine ecosystems are rare. This is not surprising since polar regions arelargely only accessible by means of expensive modern infrastructure and instrumentation. In 1999, theAlfred Wegener ... -
