Das Projekt "Abschaetzung der Konsequenzen globaler Veraenderungen fuerdie Barentsee-Region: Die Barentsee-Wirkungs-Studie" wird vom Umweltbundesamt gefördert und von Universität Münster, Institut für Geophysik durchgeführt. BASIS aims to provide an integrated assessment of global change impacts on cultural and socio-economic systems dependent on renewable and non-renewable resources in the Barents Sea region. This main goal is going to be addressed through the following objectives: 1) BASIS will assess the likely magnitude of global changes on regional to sub-regional scales in the Barents region, 2) BASIS is going to provide insight into the consequences of global changes for terrestrial, freshwater and marine ecosystems, 3) BASIS aims to develop an integrated assessment of global change impacts for a number of major economic sectors (fishery, forestry, reindeer herding) in the Barents region, 4) BASIS will determine major changes in the socio-economic structure of the Barents region and will determine the conditions for a sustainable development in the region under conditions of global change. Thus, BASIS addresses both impacts of global changes on the environmental and societal level within a 20 to 50 years time frame in the Barents region. We explicitly do not limit our considerations to climate alone and will also include the impacts of contaminants on the region. Research activities embrace and combine: extensive base case studies in relevant sectors on both levels, biological and hydrological field work, the modelling of major environmental (marine) and socio-economic processes and the generation of predictive scenarios of development under conditions of global change. An important element of the study will be a dedicated, collectively accessible (via the Internet) data base and GIS infrastructure, which will also be open to other interested parties. The information and consultation of local and indigenous stakeholders and their feedback with regard to the implementation and execution as well as the results of BASIS will comprise an essential element of the study. BASIS involves 17 partners and is organized in four task each comprised of three subtasks: Task 1) Ocean climate and fisheries. Task 2) Impacts of global change on major terrestrial natural resources, permafrost dynamics and the hydrological regime. Task 3) The integrated effects of global changes on the socio-economic system of the Barents region and conditions for sustainable development in the region. Task 4) Integration/synthesis, data collection/dissemination and stakeholder involvement. The BASIS subtasks are, by necessity, ie , by the interdisciplinary nature of the issues addressed, closely linked and require extensive exchange and collaboration between the study partners. This will be facilitated trough regular communication and meetings as well as through the aforementioned BASIS data base/GIS. BASIS contributes to area 1,1,4; 1,1,4,2 and area 4.3 of the 4th EC Framework Programme in the Field of Environment and Climate. The main benefits to be gained can be summarized on two levels ...
Das Projekt "Systemstudie Ostsee (BASYS), Teilprojekt 5: Atmosphaerische Belastung (GKSS-Teil)" wird vom Umweltbundesamt gefördert und von GKSS-Forschungszentrum Geesthacht, Institut für Gewässerphysik durchgeführt. The methodologies chosen in BASYS cover the application of a selected range of modern analyses of variables sampled in the field, data processing and model tools which are described in detail in the individual subprojects. Generally, the approach of BASYS to meet the objectives covers time scales from seasons, years, decades and centuries including the postglacial development of the ecosystem to which all subprojects will contribute individually as well as collectively: - Present day fluxes on biogenic and non-biogenic matter into and within the system are investigated on seasonal and annual scales in the pelagial and the benthal from the coast-line to the deep basins. - Natural variability in the ecosystem on the decadal scale is analysed by evaluation of historical data on climatology, hydrography, chemistry and biology including anecdotal information which will reach into the preindustrial period. - Results will be integrated by model simulation, modeI experiments and data assimilation including hindcasting of 20 to 100 years. - Time scales from 5,000 years BP to present are followed by the use of a variety of proxies for ecosystem variables in laminated sediments with high resolution particularly for the last 500 years.
Das Projekt "BASIS: Ein Feldexperiment von BALTEX" wird vom Umweltbundesamt gefördert und von Universität Hamburg, Zentrum für Meeres- und Klimaforschung, Meteorologisches Institut durchgeführt. Das Projekt BASIS (Baltic-Air-Sea-Ice Study) ist ein Unterprojekt von BALTEX (Baltic Sea Experiment). BASIS zielt generell auf ein verbessertes Verstaendnis und eine verbesserte Modellierung des Energie- und Wasserkreislaufes in und ueber der Ostsee unter winterlichen Bedingungen. Spezielles Ziel ist es, einen experimentellen Datensatz zu gewinnen und zu analysieren zur Verifikation und Verbesserung gekoppelter Atmosphaere-Eis-Ozean-Modelle. Dazu fand unter Beteiligung von finnischen, schwedischen und deutschen Forschungsgruppen aus den Bereichen Maritime Meteorologie, Physikalische Ozeanographie, Meereisforschung und Fernerkundung im Februar/Maerz 1998 ein umfangreiches Feldexperiment im Bottnischen Meerbusen statt.
Das Projekt "BISYS - Luftschadstoff-Monitoring durch automatisierte Bildaufnahme und -auswertung von Flechten" wird vom Umweltbundesamt gefördert und von Universität Bremen, Fachbereich 2 Biologie,Chemie, Pflanzenökologie durchgeführt. Millimetergrosse Flechten-Mikrotransplantate, auf speziellen Traegern (Saeulenblockverfahren) montiert, werden fuer 4-8 Wochen exponiert (Gitternetzverfahren). Eine automatische Farbfotografiereinrichtung mit gleichzeitiger Computer-programmierter Flaechenmessung und Datenablage gestattet die Bestimmung des Flaechenwachstums. Die Ergebnisse werden in Gitternetzkarten dargestellt. Die monolithische Apparatur ist noch in Weiterentwicklung.
