Differences in the properties of the bottom sediments in the system of Wdzydze Lakes (Northern Poland)
humic acids lake bottom sediments
2015/2/3
The influence was determined of the anthropo-pressure on the changes in the properties of the bottom sediments, with particular consideration given to the properties of humic acids formed in the sedim...
Constrained microbial processing of allochthonous organic carbon in boreal lake sediments
boreal lake sediments Constrained microbial processing
2014/4/4
We investigated sediment bacterial metabolism in eight lakes with different inputs of allochthonous and
autochthonous organic carbon in south-central Sweden. Sediment bacterial production, mineraliza...
ON THE ADHESION OF PORE WATER IN FINNISH ARGILLACEOUS SEDIMENTS OF DIFFERENT AGE
ADHESION PORE WATER FINNISH ARGILLACEOUS SEDIMENTS DIFFERENT AGE
2009/10/30
In this investigation the conduct of pellicular water influenced by adhesion
forces in fine grain soils of different age and at different degrees
of consolidation is demonstrated. Because of sparse ...
Observations of Ice and Its Sediments on the Baltic Sea Coast
Observations of Ice Sediments Baltic Sea Coast
2009/10/23
Ice samples were taken in winter 1996 for determining the quality and quantity
of sediment inclusions (suspended matter). The study area was the coast of the
Gulf of Finland in the Baltic Sea. The d...

2009/6/8
Long term studies of fluvial sediment processes in the Plynlimon catchments have contributed to the assessment and quantification of plantation forestry impacts in British upland catchments, at all s...
Faecal sterols as indicators of sewage contamination in estuarine sediments of the Tay Estuary, Scotland：an extended baseline survey
Faecal sterols sewage contamination estuarine sediments
2009/5/18
Sterol ratios are used to identify sources, occurrence and partitioning of faecal matter in sediments of the Tay Estuary, Scotland. The 5β/(5α+5β) ratio is used to discriminate between sewage and biog...

Features and sources of organic components in surface sediments of Lake Nishi-inbanuma in Chiba Prefecture, Japan
eutrophic lake Lake Nishi-inbanuma organic constituents surface sediment
2009/4/2
Lake Nishi-Inbanuma (area 680 ha, average depth 1.8 m) in northwest Chiba Prefecture, Japan, is known as a typical eutrophic lake. We studied organic components in the surface sediments (0-5 cm) of th...
