Oxygen depletion in Lake Geneva

Low oxygen concentrations remain a global concern for the ecological health of lakes. High nutrient inputs and climate-induced changes in stratification and mixing are anthropogenic threats which largely impact aquatic oxygen budgets and overall ecosystem ...

Calibration and deployment of POCIS and Chemcatcher for the monitoring of explosives on lake-bottom sediments

Luiz Felippe De Alencastro, Nicolas Estoppey

Between 1920 and 1967, approximatively 8000 tons of ammunition waste was dumped into some Swiss lakes. Previous studies based on grab sampling revealed small traces of cyclotetramethylenetetranitramine (HMX), cyclotrimethylenetrinitramine (RDX) and pentaer ...

Minimal model for double diffusion and its application to Kivu, Nyos, and Powell Lake

Alfred Johny Wüest, Marco Toffolon

Double diffusion originates from the markedly different molecular diffusion rates of heat and salt in water, producing staircase structures under favorable conditions. The phenomenon essentially consists of two processes: molecular diffusion across sharp i ...

Parameterization of bottom mixed layer and logarithmic layer heights in central Lake Erie

Damien Bouffard

The bottom boundary layer in lakes lies directly above the sediments and influences both hydrodynamic processes and biogeochemical fluxes. Several parameter-based models have been developed to predict the boundary layer characteristics, but the relative ac ...

Cholera in the Lake Kivu region (DRC): Integrating remote sensing and spatially explicit epidemiological modeling

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Flavio Finger, Allyn Christine Knox, Marino Gatto

Mathematical models of cholera dynamics can not only help in identifying environmental drivers and processes that influence disease transmission, but may also represent valuable tools for the prediction of the epidemiological patterns in time and space as ...

Modelling Lake Kivu water level variations over the last seven decades

Alfred Johny Wüest, Martin Schmid

This study aimed at analysing the hydrological changes in the Lake Kivu Basin over the last seven decades with focus on the response of the lake water level to meteorological factors and hydropower dam construction. Historical precipitation and lake water ...

Morphology of pillow-hollow and quilted-cover bedforms in Lake Geneva, Switzerland

David Andrew Barry, Ulrich Lemmin, Yosef Akhtman, Nicolas Le Dantec, Dragos Constantin

Extensive areas of the bottom of Lake Geneva are covered with bedforms that have been referred to as pillow-hollows and quilted-cover pattern by prior observers, as well as with sediment waves and trenches. These structures are decimeter to meter scale. A ...

Deployment of a dynamic penetrometer from manned submersibles for fine-scale geomorphology studies

David Andrew Barry, Ulrich Lemmin, Nicolas Le Dantec

Dynamic penetrometers reveal information about seafloor strength, stratification, stability, and sediment remobilization. However, positioning is often limited to a range of meters making it difficult to target small-scale geomorphologic features. Deployme ...

Sources, Spreading and Fate of Antibiotic Resistance Genes and Resistant Bacteria in Vidy Bay, Lake Geneva, Switzerland

Nadine Czekalski

Increasing numbers of multiresistant bacterial pathogens cause severe health problems on a global scale. Large quantities of bacteria and their resistance genes are discharged into natural environments via human and animal waste. Not much is known so far a ...

Diffusive-type of double diffusion in lakes - a review

Alfred Johny Wüest, Martin Schmid

This chapter is a contribution in honour of Gerhard H Jirka, who has been fascinated by the amazing variety of small-scale structures that nature surprises us with, particularly in stratified natural waters. Here, we focus on the diffusive regime of double ...
