Small scale controls of greenhouse gas release under elevated N deposition rates in a restoring peat bog in NW Germany
(Biogeosciences, 2008)In Central Europe, most bogs have a history of drainage and many of them are currently being restored. Success of restoration as well as greenhouse gas exchange of these bogs is influenced by environmental stress ... -

Small shards and long distances — three cryptotephra layers from the Nahe palaeolake including the first discovery of Laacher See Tephra in Schleswig‐Holstein (Germany)
; van den Bogaard, Christel (Journal of Quaternary Science, 2020-12-13)
Investigations of Lateglacial to Early Holocene lake sediments from the Nahe palaeolake (northern Germany) provided a high‐resolution palynological record. To increase the temporal resolution of the record a targeted search ... -
Small-scale diagenetic facies heterogeneity controls porosity and permeability pattern in reservoir sandstones
;; ; (Environmental Earth Sciences, 2020-09-15)
The fluvial-aeolian Upper Rotliegend sandstones from the Bebertal outcrop (Flechtingen High, Germany) are the famous reservoir analog for the deeply buried Upper Rotliegend gas reservoirs of the Southern Permian Basin. ... -
Small‐angle neutron scattering of long‐wavelength magnetic modulations in reduced sample dimensions
(Journal of Applied Crystallography, 2022-12-15)Magnetic small‐angle neutron scattering (SANS) is ideally suited to providing direct reciprocal‐space information on long‐wavelength magnetic modulations, such as helicoids, solitons, merons or skyrmions. SANS of such ... -
Small‐angle X‐ray scattering from GaN nanowires on Si(111): facet truncation rods, facet roughness and Porod's law
(Acta Crystallographica Section A, 2020-12-24)Small‐angle X‐ray scattering from GaN nanowires grown on Si(111) is measured in the grazing‐incidence geometry and modelled by means of a Monte Carlo simulation that takes into account the orientational distribution of the ... -
Snowfall-albedo feedbacks could have led to deglaciation of snowball Earth starting from mid-latitudes
; ; ; ; (Communications Earth & Environment, 2021-05-14)
Simple and complex climate models suggest a hard snowball – a completely ice-covered planet – is one of the steady-states of Earth’s climate. However, a seemingly insurmountable challenge to the hard-snowball hypothesis ... -
Snowmobile impacts on snowpack physical and mechanical properties
(The Cryosphere, 2018)Snowmobile use is a popular form of winter recreation in Colorado, particularly on public lands. To examine the effects of differing levels of use on snowpack properties, experiments were performed at two different ... -
Social Entrepreneurship Status Quo 2009

Socio-technical energy scenarios: state-of-the-art and CIB-based approaches
; ; ; ; ; (Climatic Change, 2020-03-02)
Energy conversion is a major source of greenhouse gas (GHG) emissions, and energy transition scenarios are a key tool for gaining a greater understanding of the possible pathways toward climate protection. There is consensus ... -
Soil age and soil organic carbon content shape biochemical responses to multiple freeze–thaw events in soils along a postmining agricultural chronosequence
; (Biogeochemistry, 2021-06-07)
Freeze–thaw (FT) events exert a great physiological stress on the soil microbial community and thus significantly impact soil biogeochemical processes. Studies often show ambiguous and contradicting results, because a ... -
Soil erosion and sediment transport modelling using hydrological models and remote sensing techniques in Wadi Billi, Egypt
; ; (Modeling Earth Systems and Environment, 2021-03-29)
Modelling soil erosion and sediment transport are vital to assess the impact of the flash floods. However, limited research works have studied sediment transport, especially in Egypt. This paper employs the HEC-HMS lumped ... -
Soil greenhouse gas fluxes following conventional selective and reduced-impact logging in a Congo Basin rainforest
; ; ; (Biogeochemistry, 2020-11-03)
Selective logging is among the main causes of tropical forest degradation, but little is known about its effects on greenhouse gas (GHG) fluxes from highly weathered Ferralsol soils in Africa. We measured soil CO2, N2O, ... -
Soil organic carbon allocation and dynamics under perennial energy crops and their feedbacks with soil microbial biomass and activity
; (Soil Use and Management, 2020)
The cultivation of perennial instead of annual energy crops has received growing interest. Previous studies identified numerous beneficial effects of perennial energy crop (PEC) cultivation for the agricultural landscape ... -
Soil organic matter turnover rates increase to match increased inputs in grazed grasslands
; ; ; ; ; ; ; (Biogeochemistry, 2021-08-27)
Managed grasslands have the potential to store carbon (C) and partially mitigate climate change. However, it remains difficult to predict potential C storage under a given soil or management practice. To study C storage ... -
Soil resistivity measurements to evaluate subsoil salinity in rice production systems in the Vietnam Mekong Delta
(Near Surface Geophysics, 2023-06-14)Abstract Rice is a staple crop in the Vietnam Mekong Delta (VMD) in which more than half of ...

Solar Activity Driven 27‐Day Signatures in Ionospheric Electron and Molecular Oxygen Densities
; (Journal of Geophysical Research: Space Physics, 2022-09-13)
The complex interactions in the upper atmosphere, which control the height‐dependent ionospheric response to the 27‐day solar rotation period, are investigated with the superposed epoch analysis technique. 27‐day signatures ... -
Solar noble gases in an iron meteorite indicate terrestrial mantle signatures derive from Earth’s core
; ; ; ; (Communications Earth & Environment, 2021-05-14)
Noble gases are important tracers of planetary accretion and acquisition of volatiles to planetary atmospheres and interiors. Earth’s mantle hosts solar-type helium and neon for which 20Ne/22Ne ratios ... -
Solving the system of radiation magnetohydrodynamics for solar physical simulations in 3d
(Univ. Freiburg (Breisgau), 2003)In this study we present a finite-volumen scheme for solving the equations of radiation magnetohydrodynamics in two and three space dimensions. Among other applications this system is used to model the plasma in the solar ... -
