From observations to 3D forecasts: Data assimilation for high resolution lakes monitoring

Lake mesoscale processes have no secrets for artists, they have some for scientists and policy-makers. In the introduction to this dissertation, we saw that poets and painters depict the lake with rich variability. This vision conflicts with conventional a ...

Spatial and temporal changes of primary production in a deep peri-alpine lake

Alfred Johny Wüest, Damien Bouffard, Tiit Kutser

Lake productivity is fundamental to biogeochemical budgets as well as estimating ecological state and predicting future development. Combining modelling with Earth Observation data facilitates a new perspective for studying lake primary production. In this ...

Spatial variability of multi-annual seasonal surface heat flux patterns of Lake Geneva

David Andrew Barry, Ulrich Lemmin, Andrea Cimatoribus, Abolfazl Irani Rahaghi

The dynamics of the spatiotemporal surface heat flux (SurHF) of Lake Geneva (Switzerland/France) was estimated for a 7-y period. Data sources included hourly maps of over-the-lake assimilated meteorological data from a numerical weather model and Lake Surf ...

Oxygen depletion in Lake Geneva

Robert Vincent Schwefel

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 ...

Physical-biological interactions - implications for biogeochemistry, productivity, export, diversity and transport

Alfred Johny Wüest, Damien Bouffard, Isabel Blanca Sophie Kiefer

Analysis of chlorophyll-a map from remote sensing satellite data (MERIS) showed a consistent low concentration biomass in the middle of Lake Geneva for about two weeks in autumn 2009. A three dimensional hydrodynamic model (Delft3D-flow) validated with tem ...

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 ...

Integrating Information Sources for Inland Waters - A New Global Framework for Lakes Modelling and Monitoring

Theo Baracchini

Like islands, lakes are not only unique geographical features, but also ecological concepts on their own. Their exceptional variability has been studied numerous times, yet no unique framework capable of reproducing the wide range of lake dynamics observed ...

Seasonal Spatial Patterns of Surface Water Temperature, Surface Heat Fluxes and Meteorological Forcing Over Lake Geneva

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

In many lakes, surface heat flux (SHF) is the most important component controlling the lake’s energy content. Accurate methods for the determination of SHF are valuable for water management, and for use in hydrological and meteorological models. Large lake ...

Origine des microplastiques en eau douce

Aïdatou Sakho

Microplastics in freshwater are becoming of emerging concerns. In Switzerland, some recent studies reveals the microplastics pollution of Swiss lakes and rivers. The aim of the present study is to improve the understanding of the origins of this pollution. ...

Surface heat flux variability of a large lake: Lake Geneva, Switzerland

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

The heat budget of a lake is a fundamental component of physical limnology, and is strongly dependent on the surface heat flux. However, the surface energy exchange depends on several factors, making it difficult to estimate. In this study we employed seve ...
