IRON METABOLISM IN TWO BASINS OF A LAKE NEAR OSLO,NORWAY
IRON METABOLISM TWO BASINS A LAKE NEAR OSLO
2009/10/30
Langlivann and Himtjern are two basins in a lake situated on rocks poor
in lime and with coniferous forest and bogs in the surroundings. The lake
is fundamentally oligotrophic. The influence of allo...

Acid Precipitation Small Acid Lake Southern Norway
2009/10/29
Langtjern is an acid lake situated in south-central Norway, 516 m above sea level.
The watershed is underlain by biotite gneisses and granites. Coniferous forests
cover 63% of the watershed, while 1...

2009/10/28
Within three areas in Southeastern Norway, Lake Mjosa district, As and Moss
- Jeloy, groundwater samples for chemical analysis were collected during the
years 1971-77 from 98 drilled wells in bedroc...
Groundwater Discharge through Springs with Well-Defined Outlets A Case Study from Jeløya–Moss,S. Norway
Groundwater Discharge Well-Defined Outlets Jelø ya–Moss
2009/10/28
From the area of JeLya - Moss, southern Norway, five springs draining
fissured-rock aquifers, and one artesian well draining confined water from a
sand and gravel aquifer were studied during the yea...
The chemistry of ground- and surface-water in areas of similar geologic settings
are compared by plotting the equivalent concentrations of each component
in an XY-diagram. The deviations of each che...
Profiles of Nitrogen Species in a Sand-Silt Aquifer at Haslemoen,Solør,South Norway
Nitrogen Species Sand-Silt Aquifer Haslemoen
2009/10/27
Chemical profiles of water in the vadose zone and in the upper part of the
groundwater from a water-table sand-silt aquifer at Haslemoen, South Norway,
have been studied. Filter tips attached to ste...

Factor analysis investigated the relationship between different compounds of nitrogen,
phosphorus, potassium and suspended dry matter in runoff from catchments
in agricultural areas in southern and ...
Seasalt Effects on the Acid Neutralizing Capacity of Streamwaters in Southern Norway
Seasalt Effects Acid Neutralizing Capacity Southern Norway
2009/10/26
Input of neutral salt, primarily NaCI, from sea spray is an important factor for shortterm
acidification of surface water, primarily in already acidified areas, because Na
may substitute for H+ and ...
