Breathing sediments: The control of diffusive transport across the sediment-water interface by periodic boundary-layer turbulence
We performed combined in situ measurements of bottom boundary-layer turbulence and of diffusive oxygen fluxes at the sediment-water interface in a medium-sized mesotrophic lake. The turbulence wasExpand

Sediment trapping by dams creates methane emission hot spots.
Inland waters transport and transform substantial amounts of carbon and account for ∼18% of global methane emissions. Large reservoirs with higher areal methane release rates than natural watersExpand

Boundary mixing in the thermocline of a large lake
[1] High-resolution measurements of near-bottom temperature stratification and current velocity were performed on the sloping boundary of a large lake at the depth of the seasonal thermocline. TheExpand

Turbulent mixing and phytoplankton spring bloom development in a deep lake
A one-dimensional (1-D) mechanistic phytoplankton model combined with a 1-D hydrodynamic model was applied to simulate phytoplankton growth during winter and spring in deep monomictic Upper LakeExpand

Dynamics of Turbulence in Low-Speed Oscillating Bottom-Boundary Layers of Stratified Basins
This paper focuses on the impact of an oscillating low-speed current on the structure and dynamics of the bottom-boundary layer (BBL) in a small stratified basin. A set of high-resolution currentExpand

Pumping methane out of aquatic sediments - ebullition forcing mechanisms in an impounded river
Freshwater systems contribute significantly to the global atmospheric methane budget. A large fraction of the methane emitted from freshwaters is transported via ebullition. However, due to itsExpand

The relative importance of wind and ship waves in the littoral zone of a large lake
Surface waves and their interactions with sediments and benthic organisms are the main hydrodynamic process affecting littoral ecosystems. Here, we present a long-term data set on surface-waveExpand

Mixotrophs combine resource use to outcompete specialists: Implications for aquatic food webs
The majority of organisms can be grouped into those relying solely on photosynthesis (phototrophy) or those relying solely on the assimilation of organic substances (heterotrophy) to meet theirExpand

Response of Lake Kivu stratification to lava inflow and climate warming
During the eruption of Nyiragongo Volcano in January 2002 about 10 6 m 3 of lava entered Lake Kivu. The high concentrations of CO2 and CH4 dissolved in the deep waters of Lake Kivu raised seriousExpand
