North Atlantic Drift Sediments Constrain Eocene Tidal Dissipation and the Evolution of the Earth‐Moon System
(Paleoceanography and Paleoclimatology, 2023-02-09)Cyclostratigraphy and astrochronology are now at the forefront of geologic timekeeping. While this technique heavily relies on the accuracy of astronomical calculations, solar system chaos limits how far back astronomical ... -
Northeast Siberian Permafrost Ice‐Wedge Stable Isotopes Depict Pronounced Last Glacial Maximum Winter Cooling
(Geophysical Research Letters, 2021-04-09)Stable isotopes (δ18O, δD) of wedge ice hold potential to reconstruct past winter climate conditions. Here, we present records of the marine isotope stages (MIS) 3 and 2 including the last Glacial maximum (LGM) from Bol’shoy ... -
Northern Adelaide Plains Prescribed Wells Area groundwater monitoring status report 2002
(Department of Water, Land and Biodiversity Conservation, Adelaide, SA2002)Prescribed Wells Area (PWA) was established in the early 1960s, in order to monitor groundwater levels and salinity (Fig. 1). The number of wells monitoring water levels, particularly in the Tertiary Aquifers (T1 and T2) ... -
Northward Propagation of the Intertropical Convergence Zone and Strengthening of Indian Summer Monsoon Rainfall
(Geophysical Research Letters, 2020-11-29)Since 2002, there has been a clear increase in Indian summer monsoon rainfall (ISMR). We demonstrate that this increase is associated with a change in the dynamics of the Intertropical Convergence Zone (ITCZ). Using a ... -
Not All Clear Air Turbulence Is Kolmogorov—The Fine‐Scale Nature of Atmospheric Turbulence
(Journal of Geophysical Research: Atmospheres, 2023-01-20)We study a strong clear air turbulence (CAT) event experienced by the German High‐Altitude Long‐Range research aircraft (HALO) during the Southern Hemisphere Transport, Dynamics, and Chemistry campaign. HALO encountered ... -
Not herbs and forbs alone: pollen‐based evidence for the presence of boreal trees and shrubs in Cis‐Baikal (Eastern Siberia) derived from the Last Glacial Maximum sediment of Lake Ochaul
(Journal of Quaternary Science, 2021-03-16)A new accerator mass spectrometry (AMS)‐dated sedimentary record from Lake Ochaul (54°14′N, 106°28′E; 641 m a.s.l.) in Eastern Siberia covers the interval from ca. 27 850 to 20 400 cal a bp at ca. 180‐year resolution and ... -
Notes on some Pleistocene mammal migrations from the Palaearctic to the Nearctic
(E&G – Quaternary Science Journal; Vol.14, No. 1)Die Einwanderungen einiger paläarktischer Säugetiere ins Nearktikum werden folgendermaßen datiert: Smilodontine Säbelzahnkatzen Elster (Kansan). Schwarzbären Elster (Kansan). Braunbären, bzw. Grizzlybären Wurm (Wisconsin). ... -
Notes on the Tertiary and Pleistocene Geology of East Gelderland, The Netherlands
(E&G – Quaternary Science Journal; Vol.23-24, No. 1)Für den Raum des östlichen Teiles der Provinz Gelderland wurden, im Hinblick auf den für die Zukunft zu erwartenden starken Anstieg des Trink- und Industriewasserbedarfes, in den Jahren 1964 bis 1967 die hydrogeologischen ... -
Nouvelles données sur la faune de Mammifères du Villafranchien inferieur de Capeni-Virghis
(E&G – Quaternary Science Journal; Vol.22, No. 1)Die Verfasser beschreiben neue Säugetierreste von zwei Lokalitäten im Nordwesten der Senke von Brasov, die dem älteren Villafranchium angehören. Die in Lignitflözen gefundene Fauna wird durch das Vorhandensein der zwei ... -
Novel experimental setup for megahertz X‐ray diffraction in a diamond anvil cell at the High Energy Density (HED) instrument of the European X‐ray Free‐Electron Laser (EuXFEL)
(Journal of Synchrotron Radiation, 2021-05-02)The high‐precision X‐ray diffraction setup for work with diamond anvil cells (DACs) in interaction chamber 2 (IC2) of the High Energy Density instrument of the European X‐ray Free‐Electron Laser is described. This includes ... -

(E&G – Quaternary Science Journal; Vol.60, No. 1)Löss-Paläoboden Sequenzen sind wichtige terrestrische Archive für die Rekonstruktion der quartären Landschafts- und Klimageschichte. Die Entwicklung neuer, quantitativerer Paläoklima-Proxies könnte in den kommenden Jahren ... -
Novel Quantification of Shallow Sediment Compaction by GPS Interferometric Reflectometry and Implications for Flood Susceptibility
(Geophysical Research Letters, 2020)Estimates of flood susceptibility and land loss in the world's coastal regions depend on our knowledge of sea level rise (SLR) from increases in ocean mass and volume, as well as knowledge of vertical land motion. Conventional ... -
Nowcasting and Predicting the Kp Index Using Historical Values and Real-Time Observations
(Space Weather, 2019)Current algorithms for the real-time prediction of the Kp index use a combination of models empirically driven by solar wind measurements at the L1 Lagrange point and historical values of the index. In this study, we explore ... -
