Ziel des Vorhabens ist die Entwicklung hochaktiver, selektiver und stabiler zeolithischer Redoxkatalysatoren für die selektive Reduktion von Stickstoffoxiden mit Ammoniak. Zu diesem Zweck werden durch Kombination katalytischer Untersuchungen mit Studien zur physikochemischen Charakterisierung von Aktivkomponente und Matrix (Methoden: EPR, ferromagnetische Resonanz (FMR), Mößbauerspektroskopie, EXAFX, XPS, ISS, UV-Vis, IR, Raman, XRD) gesicherte Erkenntnisse über die erforderliche Struktur der Redoxkomponente und der zeolithischen Matrix erarbeitet, die in verbesserte Präparationsstrategien für eine neue Katalysatorgeneration umgesetzt werden. Bezüglich der Strukturierung der Übergangsmetallkomponente ist durch Kombination katalytischer mit spektroskopischen Techniken zwischen der Wirkung isolierter Ionen auf Kationenplätzen sowie intra- bzw. extra-zeolithischer Oxidaggregate zu differenzieren, wobei dem Beweis der katalytischen Relevanz von Spezies über spektroskopische in situ-Studien (EPR, UV-Vis, Raman, EXAFS) besondere Bedeutung zukommt (1.-3. Jahr).

During the period from 1974 to 2023 various cruises from BGR acquired seismic lines worldwide. The aim of these marine expeditions were a detailed survey of the geological structure of seabed.

The late Tertiary and Quaternary development of the German EEZ was systematically inverstigated by seismic profiling. The data format is Society of Exploration Geophysicists SEG Y. For that survey the privately owned motor vessel AURELIA was chartered for a period of 24 days from the 16th of September to 10th of October 2003. A more or less equidistant E-W and N-S grid of profiles with a length of 2500 km was surveyed by high-resolution multichannel seismic system. A 0.82 litre GI-Gun was employed every 12.5 m and the reflected signals were recorded by a 300 m long streamer. Simultaneously a deep-towed HUNTEC-Boomer or a GEO-Sparker was run (150km/620km). All seismic records were processed onboard for the quality control and for a first interpretation.
Reconnaissance surveys were carried out in 1975 within the framework of the BGR program "Geoscientific studies in the North Atlantic". The data format is Society of Exploration Geophysicists SEG Y. The areas covered were the continental margin of Spitsbergen, the Barents Sea and the Norwegion continental margin. On the vessel LONGVA (30th August, 1975 - 29th September, 1975) multichannel seismic measurements were carried out on 37 lines with a total length of 2,815 km.
On the MS Explora (1st September, 1976 - 29th September, 1976) multichannel seismic measurements were carried out on 44 lines The area covered was the Barentssea. The data format is Society of Exploration Geophysicists SEG Y.
The Scientific staff and crew onboard CCGS Louis S. St. Laurent (LSL) returned September the 10th, 2001 from a scientific expedition to the Nares Strait, the northernmost waterway connecting the Arctic and Atlantic oceans. The data format is Society of Exploration Geophysicists SEG Y. The ice conditions in the strait required the support of Canada's largest ice breaker. The ship was a versatile platform for 34 scientists to accomplish their marine investigation. The LSL has a history of supporting international scientific expeditions including an oceanographic transect of the Arctic Ocean in 1994 and a biological study of the Canadian Arctic Islands in 1999. Germany (Bundesanstalt für Geowissenschaften und Rohstoffe, BGR) and Canada (Geological Survey of Canada) undertook a 5-week scientific cruise to study and explore the geological structure and evolution of the Nares Strait. The primary objective was the study of structural features relating to the formation of the Arctic Ocean and, in particular, the study of the Wegener Fault. This fault is a linear boundary between Greenland and Ellesmere Island which was noted by the German scientist Alfred Wegener in 1915 and later became the subject of a major scientific controversy. The co-operative cruise, which was planned over a period of 2 years, provided the basis for a wide range of scientific investigations, from marine seismic work and climate change studies through airborne magnetic investigations to geodetic survey measurements and geological sampling onshore. Systematic geophysical offshore studies in this key area had not been undertaken before. Where towing of seismic equipment was not possible because of ice coverage, magnetic maps were made using a helicopter-borne magnetic sensor system. Sediment and water samples taken during the cruise provide information on changes in climate and sea ice cover from the last ice-age to the present. An 11 m-long sediment core from outer Jones Sound is the longest core ever taken in the Canadian Arctic channels and holds clues to the detailed climate history of northern Baffin Bay.
