Unraveling Lake Geneva's hypoxia crisis in the Anthropocene

Limnology and Oceanography Letters, Volume 10, Issue 1, Page 113-121, February 2025.
Abstract Despite global evidence of lake deoxygenation, its duration, timing, and impacts over decadal to centennial timescales remain uncertain. This study introduces a novel model approach using 150 yr of limnological and paleolimnological data to evaluate the anthropogenic impacts on deep oxygen in Lake Geneva.

Proposition d’une approche territorialisée de la frontière lacustre : l’exemple des cartographies mentales du Léman (France/Suisse)

Sciences, Eaux & Territoires
Le concept de « frontière lacustre » pose de nombreuses questions quand il s'agit de prendre en compte la diversité des enjeux aquatiques face aux problématiques environnementales et politiques contemporaines. D'une logique de séparation, il faut penser

Daylight Photoluminescence Imaging via Optical String Switching

Solar RRL, Volume 8, Issue 19, October 2024.
The use of optical modulators enables the switching of the operating points of photovoltaic (PV) modules within one PV string connected to a utility‐scale PV inverter. This principle facilitates efficient daylight photoluminescence imaging, a noninvasive method enabling rapid image acquisition without altering PV system hardware or software.

Electrical Power Supply of Remote Maritime Areas: A Review of Hybrid Systems Based on Marine Renewable Energies

Energies, 2018
Ocean energy holds out great potential for supplying remote maritime areas with their energy requirements, where the grid size is often small and unconnected to a continental grid.

Une plage à Genève. Oui, mais quelle plage ? Les référentiels naturalistes en débat [PDF]

, 2016
En 2009, les autorités genevoises lancent un projet de plage au cœur de la ville sur les rives du lac Léman. Si un consensus se dégage rapidement quant à l'intérêt d'un tel équipement à Genève, une controverse publique émerge concernant l'impact ...

Deepwater Renewal in a Large, Deep Lake (Lake Geneva): Identifying and Quantifying Winter Cooling Processes Using Heat Budget Decomposition

Water Resources Research, Volume 60, Issue 4, April 2024.
Abstract Wintertime deepwater renewal, which is important for heat–oxygen–nutrient exchange in lakes, is traditionally considered to be mainly driven by 1D vertical convective cooling. However, differential cooling between shallow and deep waters can produce density currents that flow into deep layers.

Field Observations Reveal How Plunging Mixing and Sediment Resuspension Affect the Pathway of a Dense River Inflow Into a Deep Stratified Lake

Water Resources Research, Volume 60, Issue 4, April 2024.
Abstract The pathway of dense river inflows into lakes, which affects the lake water quality, is not accurately predicted by existing models. The pathway of a dense riverine inflow in a lake with a submerged canyon is analyzed based on measurements during a 4‐month period of weakening lake stratification and weakening density excess between river and ...

From Particles to Flocs: Revealing Where Flocculation Occurs in the Nearfield of a Negatively‐Buoyant River Plume in a Large Lake (Lake Geneva)

Journal of Geophysical Research: Oceans, Volume 129, Issue 2, February 2024.
Abstract The dynamics of sediments entering lakes in river plumes is virtually unknown. This field study provides unprecedented evidence of the initiation and evolution of suspended sediment flocculation in the nearfield of the negatively‐buoyant Rhône River plume, flowing as interflow in the thermocline of stratified Lake Geneva.

Impact of Climate Change on Photovoltaic Performance: Case Study in French Cities

Solar RRL, Volume 8, Issue 2, January 2024.
To address the effect of climate change on photovoltaic performance, a model chain is established to propagate climate projections and quantify the resulting yield losses. The investigated study cases in France highlight that the performance ratio decreases at most by 3% on the RCP 8.5 scenario mostly through module temperature losses and accelerated ...
