Directory entires that have specified Sweden as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada).

National Monitoring Programme in Sweden. The purpose is to quantify deposition (mainly of sulphur and nitrogen), and to illustrate effects in the soil, for example possible acidification. The aim of the network is to describe the current situation, regional differences, trends over time, and the effects of acid deposition. The atmospheric deposition of sulphur and nitrogen are the main causes of current acidification of ecosystems. Acidification results in substantial pH reduction in soil, groundwater, lakes and water courses. Deposition is investigated as precipitation studies in open field areas (bulk precipitation) and by throughfall studies in nearby forest stands. For sulphur and chloride, throughfall monitoring is useful for determination of total deposition. In areas, or during periods with low sulphur deposition, internal circulation in vegetation might influence results from throughfall measurements significantly. For nitrogen and base cations (mainly potassium and manganese) canopy interaction is important. Air concentrations of sulphur and nitrogen dioxide, ammonia, and ozone are measured at some locations. The observations made are: (i) air chemistry (SO2, NO2, NH3, O3); (ii) soil water chemistry (pH, Alk, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn, Fe, ooAl, oAl, Al-tot, total organic carbon); (iii) deposition in open field (precipitation, H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn); (iv) deposition in forest (throughfall, H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn). For nitrogen and base cations (mainly potassium and manganese) canopy interaction is important. Soil solution chemistry in the forest stands is used as indicator of soil conditions.
This project has been divided into two new projects: The Swedish Forest Soil Inventory and the Swedish National Forest Inventory.
The Swedish National Forest Inventory has the task of describing the state and changes in Sweden's forests. The inventory gathers basic information on forests, soils and vegetation. It includes most aspects concerning soils, for example: soil types, soil chemistry including organic matter, water conditions and content of stones and boulders. Acidification, nitrogen deposition and the contribution by soils to climate change are some of the current issues dealt with. Regularly reported variables are: forest state, injuries, and growth, logging operations, new forest stand, and environmental assessment. Invented variables on permanent sampling plots include: position in the landscape, field vegetation, site conditions, soil sampling, assesment of soil characteristics, chemical analysis of soil in O-, B-, BC- and C-horizons.
This project was previously a part of the project: National Survey of Forest Soils and Vegetation.
The Swedish Forest Soil Inventory (SFSI) is part of the national environmental monitoring programme Forests and collects information about soil conditions and chemistry from around 23 500 permanent plots throughout Sweden. One tenth of these sampling plots are re-visited each year. The inventory is commissioned by the Swedish Environmental Protection Agency and is carried out by the Department of Soil and Environment at the Swedish University of Agricultural Sciences (SLU).
The inventory gathers basic information on soils and vegetation on predominantly forest land, but also semi-natural grassland and wetland below the alpine forest limit. It includes most aspects concerning soils, for example: soil types, soil chemistry including organic matter, water conditions and content of stones and boulders. Acidification, nitrogen deposition and the contribution by soils to climate change are some of the current issues dealt with. There is a close collaboration between the SFSI and the National Forest Inventory (NFI), and the inventoried plots are a subset of the NFI plots. .
To be completed.
This project will construct detailed phosphorus budgets for polar catchments occupied by glaciers and freshwater systems undergoing rapid response to climate warming. These are Midre Lovenbreen, Svalbard; Jebsen Creek, Signy Island (maritime Antarctic) and Storglaciaren, northern Sweden. The relationship between meltwater production, pathway and phosphorus liberation from glacial sediments will be examined closely. Emphasis will be given to phosphorus sorption dynamics in turbid glacial streams and their receiving waters (fjords and lakes).
The general objective is to assess time trends and deposition loads of mercury and persistent organic pollutants from long-range atmospheric transport in Arctic environments (Greenland and north Swedish mountains) using lake sediments. The specific aims are: 1. Mercury - Study pre-industrial and industrial temporal changes in Hg concentrations in sediment records of remote lakes in Greenland and north Swedish mountains. - Address the hypothesis of 'cold condensation' (the progressive re-volatilization in relatively warm locations and subsequent condensation and deposition in cooler environments) of mercury, using a series of lake sediment cores along climate gradients: in Greenland from the inland ice sheet towards the coast and in the Swedish mountains from high altitudes down to the boreal forest. 2. POPs - Make a screening to establish which persistent organic pollutants are present in recent lake sediments in remote sites in Greenland and the north Swedish mountains. Besides PCBs, HCH, DDT and other pesticides, there are new environmental threats such as brominated flame retardants, such as PDBEs, which are of particular interest. The increasing use of PBDE and other brominated compounds may lead to increasing concentrations in the Arctic environment. However, very little is known about the levels of PBDEs as well as other POPs in sediments from the Arctic. - Analyse test series of selected POPs using a lake sediment core to assess temporal trends and a number of surface sediment samples from different lakes to assess spatial variability in concentrations and cumulative fluxes of POPs in Greenland and Swedish mountain lakes. - The main purpose of this pilot study of POPs is to determine the concentrations of selected POPs in sediments from Greenland and the northern Swedish mountains and to assess how useful lake sediments are for studying temporal and spatial pollution loads of POPs in Arctic environments.
