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. .
Geochemical mapping project based on multimaterial and -elemental method covering the NW Russia and adjacent areas of Finland and Norway. NW-Russia is of strategic importance not only for Europe but also for the sosio-economic development of the whole Russia for its richness in natural resources. Their use must be based on environmentally acceptable principles. In addition, within the area exist numerous industrial centres whose environmental impacts are unknown. The information produced by the project is significant for the future development of the area and remedial measures of the environment. The project lead by the applicant, will be carried out in 1999-2003 in cooperation with Russian and Norwegian partners.
Study of the Holocene development in the coastal area of Nova Scotia and New Brunswick (Canada), in relation to sea-level movements, isostatic movements and climate development, particularly for the last 4500 years. Use of stratigraphical and sedimentological methods and of 14C-dating.
The project aims at reconstructing the environmental history in the interior Kangerlussuaq region since deglaciation. Focus is placed on the lacustrine and eolian sediments to decipher climate evolution in terms of temperature, evaporation- precipitation balance and phases of high- wind speed events. The overall objectives are to build a high-resolution (decadal-to-century scale) chronostratigraphic framework for past climate variability from the analysis of organic-rich lake sediments and peat filled basins using a variety of sediment analysis techniques (magnetostratigraphy, grainsize, sedimentfractionation techniques, AMS 14C dating, diatom-, pollen- and macrofossil analysis) and sedimentology. Research activities diatom analysis, pollen analysis, magnetic susceptibility, automated correlation techniques, grainsize, organic chemistry, sediment fractionation techniques, AMS radiocarbon dating, sedimentology, mapping, sediment transport and erosion measurements/monitoring, micro-meteorology, vegetation mapping, pollen rain studies, diatom salinity training sets, limnology
Periglacial conditions have characterized the geomorphological development of river systems and have activated eolian processes during the Quarternary ice ages in Europe. Frost and melt mechanisms have also caused deformations on micro and macro scale in soil and sediments. Specific periglacial phenomena are indicative for (paleo-) climatic conditions
In the wake of topical research issues such as global change and energy resources, one can recognize two priority targets for the study of fossil plant remains: - insight into the role of land plants and phytoplankton as monitors, recorders, motors and moderators of climatic and environmental change; -insight into the predictive value of organic remains with respect to genesis, composition, occurrence, quality and quantity of fossil fuel reserves. In harmony with these targets, current research at the Laboratory of Palaeobotany and Palynology (LPP) is aimed to provide for basic contributions to the palaeoecological study and interpretation of Palaeozoic, Mesozoic and Cenozoic plant life. Four interconnected areas of scientific emphasis are currently distinguished: - biotic change: documentation and causal analysis of changes of past plant biota in terrestrial and marine environments, both at short and long time-scales; - selective preservation: identification of the biological, physical and chemical factors that determine selective preservation of organic matter during transport, sedimentation and burial; - methodology: development and introduction of new analytical methodology relevant to the study and interpretation of fossil plant remains; - systematics: generation and compilation of systematic data aimed at the accurate identification and classification of fossil plant remains. Overview of results LPP strives after a balance between the study of land plant remains and organic-walled marine phytoplankton (mainly dinoflagellates). Research objectives are related to both short (latest Pleistocene-Holocene) and long time-scales (late Palaeozoic-Cenozoic). Short time-scales Modern land plant communities can be understood only in the light of their history since the onset of the last deglaciation (15,000 yr BP). In western and southern Europe this history is governed by the climatically induced spread of forest communities and their subsequent recession as man's influence expanded. Through fine-scale analysis (temporal and spatial, as well as systematic), of assemblages of microscopic and macroscopic plant remains, research concentrates on the accurate discrimination between autogenic, climatically induced, and anthropogenic vegetational change in contrasting physiographic entities: (1) crystalline mountains in France and the Iberian peninsula; (2) landscapes characterized by Pleistocene-Holocene eolian (sand, loess) deposition in the Netherlands and Germany; (3) fluvial plains in the Netherlands; (4) littoral landscapes in Portugal, and (5) Arctic landscapes of Spitsbergen, Jan Mayen and Greenland. Following earrlier research experiences with respect to the palaeoecological analysis of pollen assemblages from the Vosges (France), in the research period special attention was given to deciphering the complex, altitude related, late Pleistocene-Holocene pollen signals from other low mountain ranges. Results have demonstrated that the spatial distribution of vegetation patterns can be followed through time by recognizing: (1) common time-proportionate trends in pollen values, and (2) local pollen components characteristic for altitudinal vegetation zones and lake/mire development. Long time-scales For the recognition and evaluation of biotic change on long time-scales, LPP concentrates on the study of land plant and phytoplankton records from sedimentary successions that contrast with respect to: (1) time of formation (selected late Palaeozoic, Mesozoic and Cenozoic intervals); (2) paleotectonic and palaeogeographic history (intracratonic; passive and active plate margins); (3) depositional environment (terrestrial to deep-marine); and (4) biogeographic provinciality. Temporal and spatial distribution patterns of plant remains are explored for proxy variables indicative of terrestrial and marine environmental change. Investigated variables include land temperature, humidity, precipitation, runoff, sea-level, sea surface temperature, salinity, nutrient supply, productivity, organic burial rate and CO2 level. In the review period particular attention has been given to the development of palaeoecological models of dinoflagellate cyst distribution in marine sediments. It has been shown that: (1) the potential of dinoflagellates in Mesozoic and Cenozoic time-resolution may frequently exceed that of planktonic foraminifera and calcareous nannoplankton, and (2) dinoflagellates can be applied in novel ways to further the environmental understanding of depositional sequences and sedimentary cycles defined by physical (seismic, sedimentological) analysis. Although research related to global change programmes is generally restricted to the Late Tertiary-Quaternary, there is one notable exception. It is recognized that a better understanding of the patterns and processes of past mass extinctions can contribute to an understanding of present and future man-induced extinction processes. Work by LPP concentrates on the profound biotic crises at the Permian/Triassic (P/Tr) and Cretaceous/Tertiary (K/T) junctions. Study of the P/Tr land plant record has now revealed ecosystem collapse in the terrestrial biosphere. At the K/T junction, it has been demon-strated that dinoflagellates have remained immune to extinction. Independent of configurations predicted by meteorite-impact or massive volcanism, therefore, palynological studies enable high-resolution reconstruction of environmental change, both during pre-crisis times and the phases of K/T ecosystem decline and recovery.
- To support the further development of a geocryological database for the Usa Basin (East-European Russian Arctic), including key characteristics of permafrost such as distribution, coverage, temperature, active layer, etc. - To create GIS-based permafrost maps at the scale of 1:1,000,000 for the entire Usa Basin and at 1:100,000 for selected key sites. - To reconstruct the history of permafrost dynamics at key sites in the region over the last thousands of years using palaeoecological analysis and radiocarbon dating of peat deposits, and over the last few decades using remote sensing imagery and/or monitoring (base case scenario). - To predict permafrost dynamics at key sites in the region under future conditions of climate change (20-100 yrs), using a 1-dimensional permafrost model (future global change scenario). - To assess the effects of permafrost dynamics under base case and global change scenarios on urban, industrial and transportation infrastructure in the Usa Basin. Research activities Based on several representative sites, late Holocene permafrost dynamics will be characterized using palaeoecological techniques. Variability in permafrost conditions over the last few decades will be studied based on the available data from long-term monitoring station records and from a time series of remote sensing images (optional). Mathematical modelling of permafrost dynamics will be carried out for at least two sites and a forecast of permafrost degradation in the area under anticipated climate warming will be developed. The likely effects of permafrost degradation upon regional infrastructure (inhabited localities, heat and power engineering, coal and ore mines, oil and gas extracting complex, pipelines and railways) will be analyzed using a GIS approach. GIS data layers on permafrost dynamics and infrastructure will be compared in order to delimitate high risk areas based on existing infrastructure and anticipated permafrost degradation. Hereafter, the created GIS may serve as a basis for more detailed forecasting of permafrost dynamics under both natural and anthropogenic climate changes in lowland and alpine areas of the East-European Russian Arctic.
The project aims at studying the lateral and vertical (stratigraphic) variations in the composition of particulate organic debris (palynodebris sensu Boulter and Riddick, 1986) from a suite of Holocene sediment cores from off W, S, and SE Greenland, via the Reykjanes Ridge south of Iceland, to the Faeroe Islands. The main objective is to elucidate changes in paleoenvironmental and - hydrographic parameters such as temperature, trophic level, salinity, and energy in the water mass. In particular, the study aims at mapping the distribution of different species of organic walled dinoflagellate cysts in relation to these parameters.
