Seasonal change in microbial sulfur cycling in monomictic Lake Fukami-ike, Japan
Seasonal change microbial sulfur cycling monomictic Lake Fukami-ike Japan
2014/4/3
Sulfur budgets and seasonal progression of sulfur cycling processes were investigated in Lake Fukami-ike, a small monomictic lake in Japan. The sulfur isotopic mass balance shows that the main sulfur ...

Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures a lake food web
2014/4/3
Temporal variation in the baseline stable carbon isotope (d13C) value of a well-studied, productive lake was examined over a 26-yr period using archived samples of the herbivorous zooplankterDaphnia g...

Cyanobacteria carbon source for zooplankton eutrophic Lake Taihu, China, measured 13 C labeling fatty acid biomarkers
2014/4/3
Using a combined stable-isotope and fatty-acid approach, we examined carbon-transfer routes from thecyanobacteriumMicrocystisto zooplankton in eutrophic Lake Taihu, China.Microcystisis generally consi...
Characterization of stable isotope fractionation during methane production in the sediment of a eutrophic lake, Lake Dagow, Germany
stable isotope fractionation methane production in the sediment eutrophic lake Lake Dagow Germany
2014/4/18
We measuredd13CofCO2,CH4, and acetate-methyl in profundal sediment of eutrophic Lake Dagow by incubation experiments in the presence and absence of methanogenic inhibitors chloroform, bromoethane sulf...
Effect of salt exclusion from lake ice on seasonal circulation
salt exclusion lake ice seasonal circulation
2014/4/18
We describe the circulation of Tailings Lake, located 220 km north of Yellowknife, Northwest Territories,Canada. From Jul 2004 to Sep 2007, temperature and conductivity profiles were collected togethe...
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...
Multidecadal climate oscillations detected in a transparency record from a subtropical Florida lake
Multidecadal climate oscillations transparency record subtropical Florida lake
2014/4/17
Synchronous interannual variability in water transparency observed in neighboring lakes has been linked to regional precipitation and resultant runoff of dissolved organic material, but many climate f...
Seasonal differences in the evolution of damped basin-scale internal waves in a shallow stratified lake
Seasonal differences damped basin-scale internal waves a shallow stratified lake
2014/4/17
The evolution of damped basin-scale internal waves was investigated using a modal analysis for layer-stratified rotating lakes. A simple model for homogeneous oscillatory boundary layers was incorpora...

Stable isotope fractionation during the methanogenic degradation of organic matter in the sediment of an acidic bog lake, Lake Grosse Fuchskuhle
Stable isotope fractionation during the methanogenic degradation of organic matter in the sediment an acidic bog lake Lake Grosse Fuchskuhle
2014/4/16
Lake Grosse Fuchskuhle is an acidic bog lake, which develops an anoxic hypolimnion during the summer season, so that sediment organic matter is degraded anaerobically to CH4and CO2. The d13 C values o...
