Physical and chemical consequences of artificially deepened thermocline in a small humic lake – a paired whole-lake climate change experiment
Physical chemical consequences artificially deepened thermocline
2010/12/22
Climate change with higher air temperatures and changes in cloud cover, radiation and wind speed alters the heat balance and stratification patterns of lakes. A paired whole-lake thermocline manipulat...
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...

Groundwater Influenced Lake Special Redox Sulphate Conditions
2009/10/29
Transjeen, a lake in S.E. Norway investigated hydrographically from October
1969 to October 1971, consists of two basins, both of which are meromictic (lake
with lower layer which does not participa...
Effects of Acid Precipitation on a Small Acid Lake in Southern Norway
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...

Variations 87Sr/86Sr Ratio Central Sweden
2009/10/27
The 87Sr/86Sr sratiros of lake waters from eastern Central Sweden, a region
consisting mainly of 1.7-2.0 x lo9 years old granitoid rocks are reported and
discussed. The ratios range from 0.722-0.739...
Long-term Variation in the Stability of the Meromictic Lake Nordbytjernet Caused by Groundwater Fluctuations
Long-term Variation Meromictic Lake Nordbytjernet Groundwater Fluctuations
2009/10/23
A zone with permanent anoxic conditions prevailed in the deep waters of Nordbytjernet
before 1978 due to a significant depth gradient in dissolved substances.
High concentrations of manganese and bi...

Lake Ona physical and chemical conditions
2009/10/12
Studies of the physical and chemical conditions of the water of Lake Ona, Asaba, Southern Nigeria were conducted fortnightly between August 2001 and July 2003. The physical parameters of the water wer...
Studies of lake environments using stable isotope ratios of nitrogen (δ15N) and carbon (δ13C)
stable isotopes nitrogen carbon lake
2009/7/14
Increasing numbers of studies have recently used stable isotopes of nitrogen (δ15N) and carbon (δ13C) to clarify the source of nutrients in lake water and sediments, the structure and energy flow of f...
Acidification in Three Lake District Tarns：Historical Iong term trends and modelled future behaviour under changing sulphate and nitrate deposition
Acidification nitrate deposition sulphate
2009/6/8
Three upland Lake District Tarns, Scoat, Greendale and Burnmoor, have been evaluated using MAGIC (Model of Acidification of Groundwater In Catchments) to reconstruct past, present and future chemical ...
Modelling regional response of lakewater chemistry to changes in acidic deposition：the MAGIC model applied to lake surveys in southernmost Norway 1974-1986-1995
acid neutralizing capacity acidic deposition lakewater chemistry
2009/6/5
Two methods for modelling regional responses of lake water quality to changes in acidic deposition in southernmost Norway were examined. Both methods are based upon the MAGIC model but differ in mode ...
