Die vorliegende Untersuchung basiert auf einer Situationsanalyse der Produktions- und Marktstrukturen der regionalen Landwirtschaft. Neben dem Nachfrageverhalten sowie den Erwartungen und Wünschen der Verbraucher und regionalen Marktpartner der Landwirtschaft (Mikroumfeld) werden zudem übergeordnete physische, gesellschaftliche, politische und ökonomische Faktoren (Makroumfeld), die die Ausrichtung der regionalen Landwirtschaft beeinflussen, betrachtet. Die Analyse des Mikro- und Makroumfeldes setzt sich aus folgenden Projektteilen zusammen: - Analyse der landwirtschaftlichen Produktion und ihres Umfeldes, - Analyse der landwirtschaftlichen Vermarktungsstruktur und des Grades der Vernetzung der Landwirtschaft mit ihren regionalen Marktpartnern, -... |

[ 1] The timing of meltwater release in the southern Norwegian Sea in relation to millennial-scale climate variability is studied from core MD99-2283 based on down-core analysis of stable oxygen and carbon isotopes, calcium carbonate and ice-rafted debris (IRD). Between 20 and 40 calendar (cal) kyr B. P., strong Dansgaard-Oeschger cyclicity is expressed in increased carbonate content and reduced total organic carbon during warm interstadials and IRD marking the end of cold stadials. The planktonic delta(18)O record of core MD99-2283 compared to available isotopic records in the region confirms the existence of multisourced, synchronized meltwater anomalies during Heinrich ( H) events 2 to 4. It was found that the sudden release of meltwater occurs near... |

The Belgica cold-water coral banks on the eastern slope of the Porcupine Seabight are closely associated with bottom currents. In order to better understand the local temporal and spatial characteristics, as well as the palaeoclimatologic influences, a 26 m long core, taken on a small contourite drift, was studied. This sediment record of approximately 100 ka BP reveals new insights into the regional glacial and sedimentary processes, which are intrinsically linked to several geological, climatological, biological and hydrodynamic variables. The glacial sequences in the core contain six ice-rafting events (IRE). They are comparable with the North Atlantic Heinrich Events, although their characteristics show dominant influences from the proximal... |

The rapid climatic variability characterising the Marine Isotopic Stage (MIS) 3 (similar to 60-30 cal ka BP) provides key issues to understand the atmosphere-ocean-cryosphere dynamics. Here we investigate the response of sea-surface paleoenvironments to the MIS3 climatic variability through the study of a high resolution oceanic sedimentological archive (core MD99-2281, 60 degrees 21' N; 09 degrees 27' W; 1197m water depth), retrieved during the MD114-IMAGES (International Marine Global Change Study) cruise from the southern part of the Faeroe Bank. This sector was under the proximal influence of European ice sheets (Fennoscandian Ice Sheet to the East, British Irish Ice Sheet to the South) during the last glacial and thus probably responded to the MIS3... |
