The moisture sources of precipitation in the Tianshan Mountains, one of the regions with the highest precipitation in Central Asia during 1979–2017 are comprehensively and quantitatively summarized by using a Lagrangian ... -
Modeling the Transport and Deposition of 10Be Produced by the Strongest Solar Proton Event During the Holocene
; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2022-06-28)
Prominent excursions in the number of cosmogenic nuclides (e.g., 10Be) around 774 CE/775 document the most severe solar proton event (SPE) throughout the Holocene. Its manifestation in ice cores is valuable for geochronology, ... -
Benthic Carbon Remineralization and Iron Cycling in Relation to Sea Ice Cover Along the Eastern Continental Shelf of the Antarctic Peninsula
; ; ; ; (Journal of Geophysical Research: Oceans, 2022-06-28)
Rapid and profound climatic and environmental changes have been predicted for the Antarctic Peninsula with so far unknown impact on the biogeochemistry of the continental shelves. In this study, we investigate benthic ... -
Basin‐scale estimates of greenhouse gas emissions from the Mara River, Kenya: Importance of discharge, stream size, and land use/land cover
; ; ; ; ; (Limnology and Oceanography, 2022-06-23)
Greenhouse gas fluxes (CO2, CH4, and N2O) from African streams and rivers are under‐represented in global datasets, resulting in uncertainties in their contributions to regional and global budgets. We conducted year‐long ... -
Variability in the Concentration of Lithium in the Indo‐Pacific Ocean
; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-06-22)
Lithium has limited biological activity and can readily replace aluminium, magnesium and iron ions in aluminosilicates, making it a proxy for the inorganic silicate cycle and its potential link to the carbon cycle. Data ... -
Multiple Angle Observations Would Benefit Visible Band Remote Sensing Using Night Lights
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2022-06-22)
The spatial and angular emission patterns of artificial and natural light emitted, scattered, and reflected from the Earth at night are far more complex than those for scattered and reflected solar radiation during daytime. ... -
Near‐surface three‐dimensional multicomponent source and receiver S‐wave survey in the Tannwald Basin, Germany: Acquisition and data processing
; ; (Near Surface Geophysics, 2022-06-22)
Shallow 3‐D reflection seismic surveys using S‐waves have rarely been carried out, even though S‐waves can provide higher resolution subsurface images than P‐waves. We conducted a 3‐D near‐surface multicomponent source and ... -
Application of mixed‐effects modelling and rule‐based models to explain copper variation in soil profiles of southern Germany
; ; ; ; (European Journal of Soil Science, 2022-06-20)
Copper (Cu) is an essential element for plants and microorganisms and at larger concentrations a toxic pollutant. A number of factors controlling Cu dynamics have been reported, but information on quantitative relationships ... -
Mixed Layer Depth Promotes Trophic Amplification on a Seasonal Scale
; ; ; ; ; ; (Geophysical Research Letters, 2022-06-16)
The Humboldt Upwelling System is of global interest due to its importance to fisheries, though the origin of its high productivity remains elusive. In regional physical‐biogeochemical model simulations, the seasonal amplitude ... -
Mesocrystalline Architecture in Hyaline Foraminifer Shells Indicates a Non‐Classical Crystallisation Pathway

Calcareous foraminifer shells (tests) represent one of the most important archives for paleoenvironmental and paleoclimatic reconstruction. To develop a mechanistic understanding of the relationship between environmental ... -
Mapping the Brightness of Ganymede's Ultraviolet Aurora Using Hubble Space Telescope Observations
;; ; ; ; ; (Journal of Geophysical Research: Planets, 2022-06-15)
We analyze Hubble Space Telescope observations of Ganymede made with the Space Telescope Imaging Spectrograph between 1998 and 2017 to generate a brightness map of Ganymede's oxygen emission at 1,356 Å. Our Mercator projected ... -
Spatial Markov Model for the Prediction of Travel‐Time‐Based Solute Dispersion in Three‐Dimensional Heterogeneous Media
