Influence of bottom water anoxia on nitrogen isotopic ratios and amino acid contributions of recent sediments from small eutrophic Lonar Lake, central India
nitrogen isotopic ratios Influence
2014/4/2
Lonar Lake is a eutrophic, saline soda lake with permanently anoxic deep water. The high pH and
deoxygenation result in very elevated d15N of suspended particulate matter (SPM) and sediments due to
...
Phosphatases relieve carbon limitation of microbial activity in Baltic Sea sediments along a redox-gradient
carbon limitation Baltic Sea sediments
2014/4/4
The relationship between phosphatase activity and the element limiting microbial activity (carbon [C], nitrogen
[N], or phosphorus [P]) was studied experimentally in sediment from four stations in th...
Decomposition of plankton-derived dissolved organic matter in permeable coastal sediments
plankton-derived dissolved organic matter coastal sediments
2014/4/16
We tested the hypothesis that dissolved organic carbon (DOC) is degraded when filtered through permeable
shelf sediments. In a laboratory flume experiment the concave shape of DOC profiles observed i...
Sources of nitrogen used for denitrification and nitrous oxide formation in sediments of the hypernutrified Colne, the nutrified Humber, and the oligotrophic Conwy estuaries, United Kingdom
denitrifi cation nitrous oxide
2014/4/30
Rates of denitrification and nitrous oxide (N2
O) formation, and the sources of N2
and N2
O, were examined by
the isotope-pairing technique in three U.K. estuaries (Colne, Humber, Conwy), wh...
Quantitative and qualitative relationships between planktonic diatom communities and diatom assemblages in sedimenting material and surface sediments in Lake Baikal, Siberia
Quantitative qualitative relationships Lake Baikal Siberia
2014/5/21
Endemic planktonic diatoms are a major component of Lake Baikal sediments during interglacial periods. To
investigate how these diatom assemblages are altered during sediment formation, quantitative ...
