Mineralization pathways in lake sediments with different oxygen and organic carbon supply
Mineralization pathways lake sediments different oxygen organic carbon supply
2014/4/17
The intensity and pathways of mineralization of sedimentary organic matter were investigated in eutrophic Lake Zug, Switzerland. In a depth transect (25–180 m) from oxic to anoxic bottom water we reco...
Geochemical processes and chemosynthetic primary production in different thiotrophic mats of the Ha˚kon Mosby Mud Volcano (Barents Sea)
Geochemical processes chemosynthetic primary production different thiotrophic mats of the Ha˚ kon Mosby Mud Volcano
2014/4/16
We have investigated if in a cold seep methane or sulfide is used for chemosynthetic primary production and if
significant amounts of the sulfide produced by anaerobic oxidation of methane are oxidiz...
Cycling of calcite in hard water lakes of different trophic states
Cycling of calcite hard water lakes different trophic states
2014/5/4
Based on oxygen (O2), pH, calcium (Ca2+), and carbonate (CO32-) sediment pore-water concentration profiles, we compare the benthic dissolution of autochthonous calcite in oligotrophic Lake Lucerne and...
Pore-water advection and solute fluxes in permeable marine sediments (II): Benthic respiration at three sandy sites with different permeabilities (German Bight, North Sea)
Pore-water advection solute fluxes permeable marine sediments Benthic respiration three sandy sites different permeabilities
2014/5/9
This contribution presents total oxygen uptake (TOU) rates and nutrient fluxes of organically poor permeable shelf sands of the German Bight. Measurements have been made in situ with the novel autonom...
