Gas Hydrates in Marine Sediments:Lessons from Scientific Ocean Drilling
Gas Hydrates Marine Sediments Scientific Ocean Drilling
2015/7/24
Certain low-molecular-weight gases, such as methane, ethane, and carbon dioxide, can combine with water to form ice-like substances at high pressure or low temperature. These compounds, commonly calle...
Oscillatory porewater bioadvection in marine sediments induced by hydraulic activities ofArenicola marina
Oscillatory porewater bioadvection marine sediments hydraulic activities of Arenicola marina
2014/4/17
We employed real-time pressure recording and high temporal resolution two-dimensional oxygen imaging to characterize the porewater bioadvection related to hydraulic activities of Arenicola marina, a w...
Simultaneous determination of in situ vertical transitions of color, pore-water metals, and visualization of infaunal activity in marine sediments
Simultaneous situ vertical transitions of color
2014/4/17
The vertical color transition from brown to gray-green in marine sediments is linked to the Fe redox boundary
and is commonly used as a proxy for biogeochemical state. We combine time-lapse sediment ...
Pore-water advection and solute fluxes in permeable marine sediments (I): Calibration and performance of the novel benthic chamber system Sandy
Pore-water advection marine sediments Calibration and performance benthic chamber system Sandy
2014/5/9
This contribution introduces the benthic chamber system Sandy that was developed for studying in situ solute fluxes in permeable sandy sediments where advective pore-water transport can dominate solut...
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...
A pH plate fluorosensor (optode) for early diagenetic studies of marine sediments
A pH plate fluorosensor early diagenetic marine sediments
2014/5/26
Pore water pH distributions are closely coupled to early diagenetic reactions and transport processes in surficial sediments. In this study, an optical plate fluorosensor for rapid two-dimensional det...
