Last Glacial central Mediterranean hydrology inferred from Lake Trasimeno’s (Italy) calcium carbonate geochemistry
(
- Boreas
, 2021-09-02)
There is still a paucity of hydrological data explaining the relationship between (rapid, millennial‐scale) climate forcing and Mediterranean rainfall since the Last Glacial. We show that distinct lake‐level fluctuations ...
Sedimentological and carbonate isotope signatures to identify fluvial processes and catchment changes in a supposed impact ejecta‐dammed lake (Miocene, Germany)
(
- Sedimentology
, 2021-06-20)
The identification and distinction of fluvial from lacustrine deposits and the recognition of catchment changes are crucial for the reconstruction of climate changes in terrestrial environments. The investigated drill core ...
Past and Future Climate Variability Uncertainties in the Global Carbon Budget Using the MPI Grand Ensemble
(
- Global Biogeochemical Cycles
, 2021-08-21)
Quantifying the anthropogenic fluxes of CO2 is important to understand the evolution of carbon sink capacities, on which the required strength of our mitigation efforts directly depends. For the historical period, the ...
Assessing Volcanic Controls on Miocene Climate Change
(
- Geophysical Research Letters
, 2022-01-18)
The Miocene period saw substantially warmer Earth surface temperatures than today, particularly during a period of global warming called the Mid Miocene Climatic Optimum (MMCO; ∼17–15 Ma). However, the long‐term drivers ...
Long‐Term Nitrate Trajectories Vary by Season in Western European Catchments
(
- Global Biogeochemical Cycles
, 2021-09-12)
Human alteration of nutrient cycles has caused persistent and widespread degradation of water quality around the globe. In many regions, including Western Europe, elevated nitrate (NO3−) concentration in surface waters ...
On incoherent diffractive imaging
(
- Acta Crystallographica Section A
, 2021-08-27)
Incoherent diffractive imaging (IDI) promises structural analysis with atomic resolution based on intensity interferometry of pulsed X‐ray fluorescence emission. However, its experimental realization is still pending and ...
Structure determination from unindexed powder data from scratch by a global optimization approach using pattern comparison based on cross‐correlation functions
(
- Acta Crystallographica Section B
, 2022-03-17)
A method of ab initio crystal structure determination from powder diffraction data for organic and metal–organic compounds, which does not require prior indexing of the powder pattern, has been developed. Only a reasonable ...
Simulated Future Trends in Marine Nitrogen Fixation Are Sensitive to Model Iron Implementation
(
- Global Biogeochemical Cycles
, 2022-02-24)
Biological nitrogen fixation is an important oceanic nitrogen source, potentially stabilizing marine fertility in an increasingly stratified and nutrient‐depleted ocean. Iron limitation of low latitude primary producers ...
Electrochemical Properties of Peat Particulate Organic Matter on a Global Scale: Relation to Peat Chemistry and Degree of Decomposition
(
- Global Biogeochemical Cycles
, 2022-02-16)
Methane production in peatlands is controlled by the availability of electron acceptors for microbial respiration, including peat dissolved organic matter (DOM) and particulate organic matter (POM). Despite the much larger ...
Multi‐Band Raman Analysis of Radiation Damage in Zircon for Thermochronology: Partial Annealing and Mixed Signals
(
- Geochemistry, Geophysics, Geosystems
, 2022-01-24)
Four zircon Raman bands were previously calibrated to give consistent estimates of the accumulated self‐irradiation α‐dose in unannealed volcanic samples. Partial annealing of radiation damage produces inconsistent values ...
