During the last decades several wells giving yields up to 100,000 llh have
been drilled in the reddish Brumunddal Sandstone, which covers an area
of approximately 10 km2 near lake Mjosa, Southern No...

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...
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 ...

Winter climate acid-sensitive catchments stream water nitrate
2009/4/29
Controls of stream water NO3 in mountainous and forested catchments are not thoroughly understood. Long-term trends in stream water NO3 are positive, neutral and negative, often apparently independent...
Effects of clear-cutting of forest on the chemistry of a shallow groundwater aquifer in southern Norway
Groundwater clear-cutting water chemistry monitoring.
2009/3/24
As part of the national monitoring programme for long-range transported air pollutants, four groundwater aquifers in southern Norway were monitored for acidification trends during the period 1980 – 19...
Future recovery of acidified lakes in southern Norway predicted by the MAGIC model
acid deposition lakes model Norway recovery
2009/3/12
The acidification model MAGIC was used to predict recovery of small lakes in southernmost Norway to future reduction of acid deposition. A set of 60 small headwater lakes was sampled annually from eit...
