Time-series measurements of chloride (Cl-) concentrations in lagoon and pore waters of an estuary on the east coast of Florida (Indian River Lagoon) demonstrate exchange of lagoon surface water to dep...
Tidal marshes and biogenic silica recycling at the land-sea interface
Tidal marshes biogenic silica
2014/5/4
We studied the seasonal exchange of biogenic silica (BSi) and dissolved silica (DSi) between a freshwater and a saltwater tidal marsh and the adjacent coastal waters. Export of DSi was observed from b...

The Water Framework Directive (WFD) poses an immense challenge to water management in Europe. Aiming at a "good ecological status" of surface waters in 2015, integrated river basin management plans ne...
Breathing sediments: The control of diffusive transport across the sediment-water interface by periodic boundary-layer turbulence
Breathing sediments diffusive transport sediment-water interface periodic boundary-layer turbulence
2014/5/22
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 was dri...
