Whole-soil warming alters microbial community, but not concentrations of plant-derived soil organic carbon in subsoil
(2021)EGUsphereSoils will warm in near synchrony with the air over the whole profiles following global climate change. It is largely unknown how subsoil (below 30 cm) microbial communities will respond to this warming and how plant-derived soil organic carbon (SOC) will be affected. Predictions how climate change will affect the large subsoil carbon pool (>50 % of SOC is below 30 cm soil depth) remain uncertain. At Blodgett forest (California, USA) ...Other Conference Item -
Stable isotope (carbon, hydrogen) variation in plants and lake surface sediments from northwestern Canada
(2021)EGUsphereHydrogen isotope ratios of leaf waxes are used to reconstruct past hydroclimate because they are correlated to meteoric/growth water hydrogen isotopes. The interpretation of these signatures from ancient sedimentary archives relies on a thorough understanding of the drivers of modern isotope variability. Studies in the high latitudes, regions that are particularly valuable in light of their vulnerability to rapid climate change, are scarce. ...Other Conference Item -

What role does tillage erosion play regarding landscape evolution of an intensively used hummocky landscape?
(2020)EGUsphereHummocky landscapes under intensive arable use are substantially affected by erosion processes. Data from the Quillow catchment (size: 196 km2; mean annual precipitation: 500 mm) in North-East Germany are used to estimate landscape-scale water and tillage erosion with the model SPEROS-C. Recent results show that tillage erosion causes substantial soil redistribution that can distinctively exceed water erosion. In consequence, truncated ...Other Conference Item -

The continued accumulation of anthropogenic carbon in the global ocean during the 2010s
(2021)EGUsphereSurface ocean pCO2-based estimates and models indicate that the ocean sink for anthropogenic CO2 (Cant) has continued to increase unabatedly over the past decade. However, the most recent global and observation-based estimate of the accumulation of Cant in the ocean interior by Gruber et al. (2019) does not extend beyond 2007, preventing an independent assessment of this increase in the magnitude of the sink. Here, we exploit about ...Other Conference Item -
Radiation, evapotranspiration, and roughness effects of urban trees on local microclimate: A modelling study
(2020)EGUsphereThe increase in urban air temperature caused by urban heat and climate change can have negative effects on the outdoor thermal comfort (OTC) as well as on the energy demand for air-conditioning. Nature-based solutions, such as the increase in urban biomass, are often proposed to mitigate excessive urban heat. Trees are expected to decrease temperatures due to shade provision on surfaces and evapotranspiration but their canopy blocks wind ...Other Conference Item -
Inferring saline tracer transport characteristics from time-lapse GPR experiments
(2021)EGUsphereMonitoring and characterization of flow and transport processes in the subsurface has been a key focus of hydrogeological research for several decades. Such processes can be relevant for numerous applications, such as hydrocarbon and geothermal reservoir characterization and monitoring, risk assessment of soil contaminants, or nuclear waste disposal strategies. Monitoring of flow and transport processes in the subsurface is often ...Other Conference Item -
Seismic detection of the Martian core by InSight
(2021)EGUsphereIntroduction: A plethora of geophysical, geo-chemical, and geodynamical observations indicate that the terrestrial planets have differentiated into silicate crusts and mantles that surround a dense core. The latter consists primarily of Fe and some lighter alloying elements (e.g., S, Si, C, O, and H). There is strong evidence from measurements of the tidal deformation of the planet that the core of Mars is presently liquid. The InSight ...Other Conference Item -
The growing exposure of Pacific coral reefs to compound extremes caused by marine heatwaves coalescing with low saturation state extremes
(2021)EGUsphereThe ocean has played a key role in mitigating the impact of climate change by taking up excess anthropogenic heat and CO2 leading to warming and increased ocean acidity, which goes in hand with a reduction of the saturation state of seawater with regard to the mineral carbonate aragonite, i.e., ΩAR. While the threats posed by these long-term changes to marine organisms and ecosystems are well recognized, only more recently has the community ...Other Conference Item
