    Abstract. Carbon dioxide partial pressures (pCO2) and CO2 fluxes on air-water interface in different trophic-level areas of Taihu Lake were calculated and corrected using alkalinity, pH, ionic strength, active coefficient, water temperature and wind speed on Cited by: 9. Warming and nutrient enrichment resulted in non-additive effects on nitrogen mineralization and denitrification (synergism), as well as on benthic fluxes of phosphate (antagonism). The mode of interaction appears to be related to the trophic level of the organisms that are the main drivers of the affected by:

    Ecohydrological interfaces between groundwater, Recently, ecohydrological research has considered biota at higher trophic levels, which lead to changes in connectivity and fluxes across the surface water sediment interface [Collins et al., ], through their movement Cited by: Normalized fluxes and flows in the NNP region sit between the two other regions (e.g., trophic and sedimentation efficiency), consistent with the intermediate traits of the NNP type (e.g., intermediate parameter values for the mesozooplankton predation and sinking rates in the model).Cited by: 1.

    Wave action and hydrodynamic processes at the water-sediment interface cause pore water fluxes in and out of the sediment (Massel, ), bringing oxygen as well as organic material into deeper sediment layers, thereby modifying redox gradients and, consequently, affecting biogeochemical processes like denitrification and/or iron, manganese and Cited by: 4. The simulated trophic state has reached lower levels (mesotrophic or lower) in 8% of the time, only. The model was run for the same period adopting sediment management practices: Scenario 1, in which annual sediment removal was considered; Scenario 2, admitting no return of phosphorus from the sediment to the water column, for instance by Cited by: 1.

Animals like worms, mollusks and echinoderms can enhance resuspension and mixing through. Results show that the relationship between annual water and sediment yields has a good correlation (R 2 = ) for horizon ; however, a low correlation (R 2 = ) was observed for horizon The analysis reveals that the water–sediment interaction will be affected due to changes of monsoon precipitation in future.

The oxygen level at the water–sediment interface depending mostly on organic matter accumulation and dissolved oxygen in the overlying water. The high rate of microbial processes and the long-time sediment inundation usually lead to an anaerobic condition at the water–sediment interface, and a denitrification process often occurs (Kemp et.

Tidal oscillations systematically flood salt marshes, transporting water, sediments, organic matter, and biogeochemical elements such as silica. Here we present a review of recent studies on these fluxes and their effects on both ecosystem functioning and morphological evolution of salt marshes.
