Das Projekt "Improved Methods for the Assessment of the Generic Impact of Noise in the Environment (IMAGINE)" wird vom Umweltbundesamt gefördert und von Müller-BBM Gesellschaft mit beschränkter Haftung durchgeführt. For the production of strategic noise maps as required under the EU Directive 2002/49/EC, improved assessment methods for environmental noise will be required. Noise from any major source, be it major roads, railways, airports or industrial activities in agglomerations, needs to be included in the noise mapping. For road and rail, improved methods will be developed in the 5th frame work Harmonoise project. These methods will be adopted to develop methods for aircraft and industrial noise in the IMAGINE project proposed here. Noise source databases to be developed in IMAGINE for road and rail sources will allow a quick and easy implementation of the methods in all member states. Measured noise levels can add to the quality of noise maps because they tend to have better credibility than computed levels. In the project proposed here, guidelines for monitoring and measuring noise levels will be developed, that can contribute to a combined product (measurement and computation) that has high quality and high credibility. Noise action plans shall be based on strategic noise maps. The IMAGINE project will develop guidelines for noise mapping that will make it easy and straightforward to assess the efficiency of such action plans. Traffic flow management will be a key element of such action plans, both on a national and a regional level. Noise mapping will be developed into a dynamic process rather than a static presentation of the situation. IMAGINE will provide the link between Harmonoise and the practical process of producing noise maps and action plans. It will establish a platform where experts and end users can exchange their experience and views. This platform should continue after the project and provide a basis for exploitation to the IMAGINE results. me Contractor: Detalrail B.V.; Utrecht; Netherlands.
Das Projekt "EURopean network of excellence for OCean Ecosystems ANalysiS (EUR-OCEANS)" wird vom Umweltbundesamt gefördert und von Stiftung Alfred-Wegener-Institut für Polar- und Meeresforschung e.V. in der Helmholtz-Gemeinschaft (AWI) durchgeführt. EUR-OCEANS aims to achieve lasting integration of European research organisations on global change and pelagic marine ecosystems, and to develop models for assessing and forecasting the impacts of climate and anthropogenic forcing on food-web dynamics (structure, functioning, diversity and stability) of pelagic ecosystems in the open ocean. The NOE will favour the progressive integration of research programmes and facilities of major research Institutes all over Europe. The long-term goal of the NOE is to create a multi-site Institute for European Research on Ocean Ecosystems under Anthropogenic and Natural forcings. The international context is provided by Global Ocean Ecosystem Dynamics (GLOBEC), and the forthcoming Integrated Marine Biogeochemistry and Ecosystem Research (IMBER) of the International Geosphere Biosphere Programme (IGBP).EUR-OCEANS' Joint Programme of Activities (JPA) comprises: (1) Integrating activities on: networking (data and model integration); (2) Jointly executed research, organised around four broad modelling tasks (together with observations and experiments) on: pelagic ecosystems end-to-end, biogeochemistry, ecosystem approach to marine resources and within-system integration; (3) Activities to spread excellence, including training of researchers, and spreading excellence to socio-economic users and to the European public (through the Association of Aquaria for EUR-OCEANS public outreach); (4) Management Activities. Administrative and Financial Coordinator: Institut Oceanographique. Governing bodies: General Assembly (Member Organisations); Executive Committee (incl. Scientific Director and the Deputy); Steering Committee (incl. Work Packages Leaders). Councils: Scientific, Intellectual, Gender Equality, and EUR-OCEANS Institute. Composition: 69 Member Organisations, from 25 states (incl. 7 Third countries); 160 PIs selected for their capacity and excellence. Close cooperation with the USA, Australia, Canada, Namibia and Japan. Prime Contractor: France Innovation Scientifique et Transfert; Paris; France.
Das Projekt "Temporal evolution of hydrothermal systems at the Mid-Atlantic Ridge (14 45 - 15 05N)" wird vom Umweltbundesamt gefördert und von Christian-Albrechts-Universität zu Kiel, Sektion Geowissenschaften, Institut für Geowissenschaften durchgeführt. Wenige Informationen gibt es bisher zur Lebensdauer von Hydrothermalsystemen, zur zeitlichen Variabilität hydrothermaler Aktivität sowie zu der Veränderung der chemischen Zusammensetzung der Fluide über geologische Zeitskalen hinweg. Anhand von Altersdatierungen hydrothermaler Ablagerungen mit Hilfe natürlicher Radionuklide sollen Dauer und Periodizität hydrothermaler Aktivität im Logatchev Feld bestimmt werden. Anhand der chemischen Zusammensetzung der Präzipitate und ihrem Alter sollen Informationen zur chemischen Variabilität der hydrothermalen Lösungen während der geologischen Vergangenheit erhalten werden. Grundlagen für diese Untersuchungen sind Bohrkerne die während der Forschungsfahrt mit FS MERIAN (2006) im Logatechev Feld gewonnen werden. Die Altersdatierung der hydrothermalen Ablagerungen, die durch die Bohrungen erhalten werden, sollen dazu beitragen, die Entwicklungsgeschichte des Logatchev Feldes in Raum und Zeit zu erforschen.
Das Projekt "Critical Limits and Effect Based Approaches for Heavy Metals" wird vom Umweltbundesamt gefördert und von Eidgenössische Forschungsanstalt für Wald, Schnee und Landschaft durchgeführt. Heavy metals are emitted in the atmosphere by industrial activities, transported through long distances, they deposit and accumulate in terrestrial ecosystems. The problem of Long-Range Transboundary Air Pollution of Terrestrial Ecosystems (LRTAP) includes cadmium (Cd), mercury (Hg) and lead (Pb) and are priority metals in the United Nations / Economic Commission for Europe (UN/ECE) Convention from 1998. Increased accumulation of Cd, Hg and Pb from anthropogenic and geogenic sources in soils especially of forest soils has led to exceedances of the current guide values defined by the environmental legislation. Especially, Hg as a global pollutant is of high ecotoxicological concern. However, little information is available on rates of atmospheric deposition, distribution, mobility of Hg compounds (methylmercury) in soils and their transfer functions in the biosphere (bioaccumulation). An impact of current Hg (Cd and Pb) concentrations on the soil ecosystem is possible but still unknown. Aims: This study is part of a comprehensive investigation to determine Hg (Cd and Pb) levels in the soil matrix, soil solution, fungi, earthworms and their food sources (soil, leaf and root litter) and to evaluate the ecotoxicological effects of Hg on the soil microbial communities. What is the current situation of Cd, Hg and Pb in Swiss forest soils? What are the transfer functions of Cd, Hg and Pb from soil to earthworms and mushrooms? Which microbial parameters (microbial activities and/or bacterial community structures) are most suitable to reveal effects of Cd, Hg and Pb on forest soils? Which heavy metal species in soil can be considered as appropriate predictors of Cd, Hg and Pb bioavailability to microbial communities in soils? Which soil bacterial groups are affected by Cd, Hg and Pb? Are the current critical limits for the total dissolved Cd, Hg and Pb, suggested by the UN/ECE, in accordance with the values estimated for Swiss forest soils? Methods: - Determination of reactive heavy metal pool in soil: Water-extractable HM; Heavy metal specific bacterial biosensors (quantification of lux-gene); Modeling of free ions (WHAM 6). - Determination of microbial activity: - Soil respiration; Nitrification; Phosphatase, beta-Glycosidase. - Changes of total bacterial communities: T-RFLP and DGGE fingerprinting of 16S rRNA gene; Cloning and sequencing; Design of specific primers for detecting HM tolerant bacterial groups.
