Nitrogen processes in aquatic ecosystems
Nature of the problem * Freshwater ecosystems play a key role in the European nitrogen (N) cycle, both as a reactive agent that transfers, stores and processes N loadings from the atmosphere andExpand

Extreme acidification in small catchments in southwestern Norway associated with a sea salt episode
During heavy storm events in January 1993 in the coastal areas of south-western Norway, a sea salt episode created extreme acidification in the afforested Svela catchment. Stream-water chlorideExpand

Inorganic nitrogen retention in acid-sensitive lakes in southern Norway and southern Ontario, Canada - a comparison of mass balance data with an empirical N retention model
In-lake retention of inorganic nitrogen species (nitrate and ammonium) was estimated from mass balances in five acid-sensitive lakes in southern Norway and eight in southern Ontario, Canada, toExpand

Linked models to assess the impacts of climate change on nitrogen in a Norwegian river basin and FJORD system.
Dynamically downscaled data from two Atmosphere-Ocean General Circulation Models (AOGCMs), ECHAM4 from the Max-Planck Institute (MPI), Germany and HadAm3H from the Hadley Centre (HAD), UK, drivenExpand

Adaptation of the Integrated Nitrogen Model for Catchments (INCA) to seasonally snow-covered catchments
Abstract. Testing of the Integrated Nitrogen model for Catchments (INCA) in a wide range of ecosystem types across Europe has shown that the model underestimates N transformation processes to a largeExpand

Manipulation of Snow in Small Headwater Catchments at Storgama, Norway: Effects on Leaching of Inorganic Nitrogen
Abstract We have manipulated the winter-time soil temperature regime of small headwater catchments in a montane heathland area of southern Norway to study the possible effects on concentrations andExpand

Natural Variability in Soil and Runoff from Small Headwater Catchments at Storgama, Norway
Abstract To provide baseline data for climate manipulation experiments in 11 small (30–268 m2) headwater catchments at Storgama, Telemark County, Southern Norway, we assessed the natural variabilityExpand
