Atomistic Simulations of The Structure of Calcium Silicate Hydrates: Interlayer Positions, Water Content And A General Structural Brick Model

Portland cement has been in use by human civilization for over a century. Yet, we do not fully understand its hydration reaction mechanisms due to the complexity of the system and its continued reaction over time making it hard to study it experimentally. ...

3D water quality modelling of a eutrophic lake

Christel Marie Tartini-Chappuis

In an environment subject to anthropogenic pressures, the understanding of lakes is crucial as they are essential for ecosystems and represent a source of the scarce accessible freshwater existing on Earth. Water quality management is especially designed t ...

Organic carbon mass accumulation rate regulates the flux of reduced substances from the sediments of deep lakes

Alfred Johny Wüest, Robert Vincent Schwefel, Martin Schmid, Bernhard Wehrli

The flux of reduced substances, such as methane and ammonium, from the sediment to the bottom water (Fred) is one of the major factors contributing to the consumption of oxygen in the hypolimnia of lakes and thus crucial for lake oxygen management. This st ...

Ecological strategies and metabolic trade-offs of complex environmental biofilms

Tom Ian Battin, Hannes Markus Peter

Microorganisms aggregated into matrix-enclosed biofilms dominate microbial life in most natural, engineered, and medical systems. Despite this, the ecological adaptations and metabolic trade-offs of the formation of complex biofilms are currently poorly un ...

The Chaoborus pump: Migrating phantom midge larvae sustain hypolimnetic oxygen deficiency and nutrient internal loading in lakes

Sabine Flury McGinnis

Hypolimnetic oxygen demand in lakes is often assumed to be driven mainly by sediment microbial processes, while the role of Chaoborus larvae, which are prevalent in eutrophic lakes with hypoxic to anoxic bottoms, has been overlooked. We experimentally meas ...

Validation of Landsat-8 and Sentinel-2 algorithms for atmospheric correction on Lake Geneva

Sonia Joëlle Dupuis

Remote-sensing of water surfaces such as large lakes is a useful tool for monitoring and understanding large-scale processes. Suspended particles in lakes can have various sources such as autochthonously produced organic matter, urban or agricultural runof ...

Are flood-driven turbidity currents hot spots for priming effect in lakes?

Damien Bouffard

In deep stratified lakes, such as Lake Geneva, flood-driven turbidity currents are thought to contribute to the replenishment of deep oxygen by significant transport of river waters saturated with oxygen into the hypolimnion. The overarching aim of this st ...

Spatial variability of Inherent Optical Properties in the perialpine lakes

Alfred Johny Wüest, Damien Bouffard, Vincent Maurice Nouchi

Accurate estimation of biogeochemical substances from remote observations requires knowledge of Inherent Optical Properties (IOPs) and their mass specific representation (SIOPs). Corresponding measurements are rather scarce for perialpine lakes, which repr ...

Bioassay battery interlaboratory investigation of emerging contaminants in spiked water extracts - Towards the implementation of bioanalytical monitoring tools in water quality assessment and monitoring

Bioassays are particularly useful tools to link the chemical and ecological assessments in water quality monitoring. Different methods cover a broad range of toxicity mechanisms in diverse organisms, and account for risks posed by non-target compounds and ...

Effects of climate change on deepwater oxygen and winter mixing in a deep lake (Lake Geneva): Comparing observational findings and modeling

Alfred Johny Wüest, Damien Bouffard, Robert Vincent Schwefel, Adrien Gaudard

Low concentrations of dissolved oxygen remain a global concern regarding the ecological health of lakes and reservoirs. In addition to high nutrient loads, climate-induced changes in lake stratification and mixing represent additional anthropogenic menace ...
