Lake surface cooling drives littoral-pelagic exchange of dissolved gases
Alfred Johny Wüest, Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda, Cintia Luz Ramon Casanas
The extent of littoral influence on lake gas dynamics remains debated in the aquatic science community due to the lack of direct quantification of lateral gas transport. The prevalent assumption of diffusive horizontal transport in gas budgets fails to exp ...
Amer Assoc Advancement Science2024Home, with what remains: A sorting-house as a form of occupancy right
North of La Rochelle, the Baie de l'Aiguillon bears witness to a structurally invasive past, partially camouflaged in its shallow waters. 400 hectares of abandoned oyster beds locally known as crassats, remnants of the shellfish industry, lie in the intert ...
2023Fish Diversity in Relation to Littoral Habitats in Three Basins of Lake Kivu (East Africa)
In total, 28 of the 29 fish species reported from the Lake Kivu basin occur in the littoral zone of the lake, but information about their structure, occurrence, and the habitats affecting their distribution is largely lacking. The lake's inshore area is po ...
MDPI2023Spatial Variability of Turbulent Mixing From an Underwater Glider in a Large, Deep, Stratified Lake
Alfred Johny Wüest, Damien Bouffard, Sébastien Lavanchy, Oscar Rodrigo Sepúlveda Steiner, Bieito Fernandez Castro, Alexander Lebaron Forrest
Recent efforts using microstructure turbulence measurements have contributed to our understanding of the overall energy budget in lakes and linkages to vertical fluxes. A paucity of lake-wide turbulence measurements hinders our ability to assess how repres ...
AMER GEOPHYSICAL UNION2023Crack tip kinematics reveal the process zone structure in brittle fracture
John Martin Kolinski, Chenzhuo Li, Xinyue Wei
When brittle hydrogels fail, several mechanisms conspire to alter the state of stress near the tip of a crack, and it is challenging to identify which mechanism is dominant. In the fracture of brittle solids, a sufficient far-field stress results in the co ...
PERGAMON-ELSEVIER SCIENCE LTD2023Density currents driven by differential cooling in lakes: occurrence, dynamics and implications for littoral-pelagic exchange
Cross-shore flows exchange water laterally in lakes, with ecological implications for the ecosystem. One example is the convective circulation induced by differential cooling, also known as the thermal siphon. This lateral flow forms when the sloping sides ...
EPFL2022Convective regimes induced by surface cooling and topography in stratified waterbodies
Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda, Cintia Luz Ramon Casanas
Gravitational convection plays a significant role in the ventilation, heat and mass distribution of aquatic systems. This study investigates thermally driven convection resulting from heat loss at the air-water interface during cooling periods in freshwate ...
Madrid2022Competition between cooling and shortwave radiation in shaping near-surface convection in pelagic waters of Lake Geneva
When lake surface waters above the temperature of maximum density 4◦C cools, the verysurface fluid parcels become denser than their neighbours below. The latter process leads to a gravitationally unstable density distribution which may trigger ‘free convec ...
2021Multi-scale investigation on mechanical behavior and microstructural alteration of C-S-H in carbonated Alite paste
Carbonation treatment is a promising option to enhance recycled concrete aggregate (RCA) quality and eventually improve concrete performance. This study investigated the multi-scale mechanical properties of calcium silicate hydrates (C-S-H) in a mature ali ...
PERGAMON-ELSEVIER SCIENCE LTD2021Effects of temperature on tidally influenced coastal unconfined aquifers
David Andrew Barry, Li Pu, Chenming Zhang
Aquifer-ocean temperature contrasts are common worldwide. Their effects on flow and salinity distributions in unconfined coastal aquifers are, however, poorly understood. Based on laboratory experiments and numerical simulations, we examined the responses ...
