Identifying and quantifying unexpected deep zooplankton diel vertical migration in a large deep lake

Ulrich Lemmin, David Andrew Barry, Htet Kyi Wynn, Valentin Kindschi, Rafael Sebastian Reiss, Violaine Florette Piton

Diel Vertical Migration (DVM), a widespread zooplankton behavior in freshwater and marine systems, affects ecological interactions and biogeochemical cycles. In lakes, DVM has mainly been studied in the upper 50 m of the water column. However, based on aco ...

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

Ulrich Lemmin, David Andrew Barry, Htet Kyi Wynn, Valentin Kindschi, Violaine Florette Piton

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 Rh & ocirc;ne Rive ...

Tracing Unconfined Nearfield Spreading of a River Plume Interflow in a Large Lake (Lake Geneva): Hydrodynamics, Suspended Particulate Matter, and Associated Fluxes

Ulrich Lemmin, David Andrew Barry, Htet Kyi Wynn, Benjamin Daniel Graf, Frédéric Charles Soulignac, Violaine Florette Piton

River inflows have a major influence on lake water quality due to their input of sediments, nutrients and contaminants. After leaving the river channel, river waters form a plume and interact with ambient lake waters. Strong hydrodynamic changes take place ...

Variability of the Red River Plume in the Gulf of Tonkin as Revealed by Numerical Modeling and Clustering Analysis

Violaine Florette Piton

We study the daily to interannual variability of the Red River plume in the Gulf of Tonkin from numerical simulations at high resolution over 6 years (2011-2016). Compared with observational data, the model results show good performance. To identify the pl ...
