Constrained microbial processing of allochthonous organic carbon in boreal lake sediments
Constrained microbial processing allochthonous organic carbon boreal lake sediments
2014/4/2
We investigated sediment bacterial metabolism in eight lakes with different inputs of allochthonous and autochthonous organic carbon in south-central Sweden. Sediment bacterial production, mineralizat...
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...
Organic carbon burial efficiency in lake sediments controlled by oxygen exposure time and sediment source
Organic carbon burial efficiency lake sediments controlled oxygen exposure time sediment source
2014/4/17
We compared the burial efficiency of organic carbon (buried OC : depositedOC) in a diverse set of 27 different sediments from 11 lakes, focusing on the potential effects of organic matter source, oxyg...
Compound-specific stable isotopes of organic compounds from lake sediments track recent environmental changes in an alpine ecosystem, Rocky Mountain National Park, Colorado
Compound-specific stable isotopes organic compounds lake sediments environmental changes alpine ecosystem Rocky Mountain National Park Colorado
2014/4/18
Compound-specific nitrogen, carbon, and hydrogen isotope records from sediments of Sky Pond, an alpine lake in Rocky Mountain National Park (Colorado, United States of America), were used to evaluate ...
Natural inactivation of phosphorus by aluminum in preindustrial lake sediments
Natural inactivation phosphorus aluminum preindustrial lake sediments
2014/4/22
Noncalcareous phosphorus (P)-rich lake sediments typically release P associated with iron hydroxide [Fe(OH)3] during the development of hypolimnetic anoxia. High concentrations of aluminum hydroxide [...
Physical and chemical predictors of diatom dissolution in freshwater and saline lake sediments in North America and West Greenland
Physical and chemical predictors diatom dissolution in freshwater saline lake sediments North America West Greenland
2014/5/4
Diatom dissolution in surface sediment samples from two regional lake datasets in the Northern Great Plains (NGP; n = 64) and West Greenland (n = 40) is assessed using a morphological approach categor...
Is phosphorus retention in autochthonous lake sediments controlled by oxygen or phosphorus?
autochthonous lake sediments phosphorus retention
2014/4/30
Eutrophication of various lakes on the Swiss Plateau was targeted in the 1980s by reducing external nutrient
loading and installing aeration/oxygenation systems. For five eutrophic lakes, three...
Effect of macrozoobenthos on two-dimensional small-scale heterogeneity of pore water phosphorus concentrations in lake sediments: A laboratory study
Effect of macrozoobenthos two-dimensional small-scale heterogeneity pore water phosphorus concentrations lake sediments A laboratory study
2014/5/9
We used mesocosms equipped with two-dimensional (2D) pore water samplers (24 rows X 24 columns, 9-mm spatial resolution) to resolve and quantify some of the complex spatial patterns in diagenetic reac...
