New insights on the mineralization of dissolved organic matter in central, intermediate, and deep water masses of the northeast North Atlantic
New insights mineralization dissolved organic matter central, intermediate deep water masses northeast North Atlantic
2014/4/2
An optimum multiparameter (OMP) analysis was applied to samples collected during a cruise in the northeast North Atlantic with the aim of objectively defining water mass realms and calculating water m...
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...
Benthic solute exchange and carbon mineralization in two shallow subtidal sandy sediments: Effect of advective pore-water exchange
Benthic solute exchange carbon mineralization
2014/4/22
We conducted four field campaigns to evaluate benthic O2
consumption and the effect of advective pore-water
flow in nearshore permeable sediments in the North Sea and Baltic Sea. Advective pore-wate...
Effect of the diffusive boundary layer on benthic mineralization and O2 distribution: A theoretical model analysis
Effect of the diffusive boundary layer benthic mineralization O2 distribution: A theoretical model analysis
2014/4/23
On the basis of a dynamic diagenetic model, we evaluate and discuss the effect of the diffusive boundary layer (DBL) on benthic O2 exchange and O2 consuming pathways. The analysis documents that the D...
Spatial and temporal patterns of mineralization rates and oxygen distribution in a permeable intertidal sand flat (Sylt, Germany)
Spatial and temporal rates oxygen distribution
2014/5/5
Oxygen distribution and benthic mineralization rates were investigated in a permeable intertidal sand flat
(permeability: 3.9 3 10211 m2
) in a transect from the low toward the high waterline. At al...
Microscale mineralization pathways in surface sediments: A chemical sensor study in Lake Baikal
Microscale mineralization pathways surface sediments A chemical sensor study Lake Baikal
2014/5/4
We used an array of ion-selective electrodes (oxygen [O2], hydrogen [H+], carbonate [CO32-], calcium [Ca2+], ammonium [NH4+], and nitrate [NO3-]) with a micromanipulator to study mineralization proces...
Role of dissolved organic matter in hypolimnetic mineralization of carbon and nitrogen in a large, monomictic lake
Role of dissolved organic matter carbon and nitrogen
2014/4/23
We tested the hypothesis that dissolved organic matter (DOM) is delivered to deep layers by convective mixing
in winter, where it contributes to the mineralization of C, N, and P in the oxygenated hy...
Transport and mineralization rates in North Sea sandy intertidal sediments, Sylt-Rømø Basin, Waddensea
Transport and mineralization rates North Sea sandy intertidal sediments, Sylt-Rø mø Basin Wadden Sea
2014/5/8
We investigated the rates of the main microbiological processes (primary production, aerobic and anaerobic carbon degradation) and transport phenomena in an intertidal sand plate with a combination of...
Competition between biological and photochemical processes in the mineralization of dissolved organic carbon
Competition biological photochemical processes
2014/5/14
The photo- and bioreactive components of dissolved organic matter (DOM) from three different environments were
determined during long-term decomposition experiments. Terrigenous DOM was collected fro...
Whole-lake mineralization of allochthonous and autochthonous organic carbon in a large humic lake (Ortrasket, N. Sweden)
Whole-lake mineralization allochthonous and autochthonous organic carbon a large humic lake
2014/6/10
Organic carbon mineralization was studied in a large humic lake (Lake Ortrasket) in northern Sweden during a well-defined summer stratification period following high water flow during snowmelt. Severa...
