Entwicklung neuer zeolithischer Redoxkatalysatoren für die selektive Reduktion von NO durch Ammoniak durch Aufklärung der Beziehungen zwischen Katalysatorstruktur und katalytischen Eigenschaften

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).

Marine Seismic Survey Profiles (MSSP) (WMS)

During the period from 1974 to 2018 various cruises from BGR acquired seismic lines worldwide. The aim of these marine expeditions was a detailed survey of the geological structure.

Processed seismic data of Cruise MSM9/3

The cruise leg MSM09/3 was conducted as a cooperative project between the Alfred Wegener Institute for Polar and Marine Research (AWI), the Federal Institute for Geosciences and Resources (BGR), the Geological Survey of Denmark and Greenland (GEUS) and Dalhousie University. The data format is Society of Exploration Geophysicists SEG Y. A geophysical survey covered areas of Baffin Bay and Davis Strait between Greenland and the Canadian Baffin Island. A component of the IPY 2007/08 Lead Project Plate Tectonics and Polar Gateways in the Earth System (PLATES & GATES), this project DAVIS GATE is aimed to develop a tectonic and sedimentary reconstruction of the opening process of this oceanic gateway. Baffin Bay and Davis Strait play an important role in the shallow water exchange from the Arctic to the Atlantic Ocean. The plate-tectonic evolution as well as the magmatic history of this region has been sparsely known and required a careful geophysical investigation in order to construct a set of gridded detailed paleotopographic maps for a complete geodynamic reconstruction of this gateway. With a set of three seismic refraction/wide-angle reflection profiles, using ocean-bottom seismometers on 62 stations, as well as multi-channel reflection seismic recordings with a 3000-m long streamer, data were acquired from the sedimentary cover to the deep crust and even from parts of the uppermost mantle. Additional seismic data supplement these profiles and provide insights into the structures of the basement and dominant fault zones such as the Ungava fault system. A parallel running magnetic survey aimed to resolve the temporal evolution of the oceanic crust of Baffin Bay. The extension and subsidence of the continental and transitional crust in the Davis Strait and the evolution of oceanic crust in the Labrador Sea and Baffin Bay could be investigated with dataset to which continuously recorded gravity anomaly data and sub-bottom profiler data also contribute. This dataset provides the basis of geometrical and physical properties of the crust required for a realistic geodynamic model which will describe the break-up and the ocean basin evolution between Greenland and Canada in terms of detailed paleo-topography.

Processed seismic data of Cruise Nares 2001

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.

Processed seismic data of Cruise ARK5/3 1988

In July/August 1988 a seismic reconnaisance survey was carried out with F.S. Polarstern on the perennially ice covered East Greenland shelf between latitudes 73°N and 81°N. The data format is Society of Exploration Geophysicists SEG Y. 14 reflection seismic lines with a total length of 2.016 km and 12 sonobuoy refraction profiles were recorded. The following results were obtained: •On the wide Holm Land shelf province north of 79°N three possible Cretaceous rift basins were observed. •A buildup of layered extrusive basaltic rocks forming a wedge of seaward dipping reflectors underlies the Holm Land continental slope. •On the Northeastern Greenland shelf province the existence of a wide sedimentary basin was demonstrated north of 76°N. •South of 76°N four volcanic structures from the continent to ocean were observed: The zone of Early Tertiary plateau basalts (zone I) that occur landward of an escarpment, a flat lying basaltic flow unit immediately seaward of the escarpment (zone II), an elongate wedge of seaward dipping reflectors (zone IIIa), a basaltic flow unit which in places shows seaward dipping beds of short length (zone IIIb), and the oceanic crust. •Dyke swarms and intrusions of inferred Neogene age were recognized at several locations.

Automatische Erkennung von Pflanzenkrankheiten mit mobilen Endgeräten und mobilem Internet zur zielgerichteten Nutzung von landwirtschaftlichen Entscheidungshilfesystemen, Teilprojekt 2

Ziel ist es Krankheitssymptome an Zuckerrübenblättern mit Hilfe von Kameras in mobilen Endgeräten (Smartphones, Handys, etc.) zu fotografieren, diese per Internet auf einen Server zu übertragen, dort durch Erkennungsroutinen analysieren zu lassen und das Ergebnis zurück zu senden. Dabei sollen durch Farb- und Mustererkennung der gesendeten Aufnahmen die möglichen Blattkrankheiten eingeschränkt werden. Aus einer Krankheitsbibliothek werden dem Nutzer Aufnahmen gesandt, so dass er ähnliche Ausprägungen der Krankheiten direkt vergleichen kann. Nach Bestimmung der Krankheit(en) kann der Nutzer durch GPS seinen Standort bekannt geben und unter Berücksichtigung weiterer Geo- und Schlagdaten im Beratungsportal der Länder ISIP (www.isip.de) eine Schaderregerprognose berechnen lassen bzw. Empfehlungen und Handlungsanweisungen abrufen. Im letzten Projektjahr ist vorgesehen, die Übertragbarkeit der Methode auf Blattkrankheiten in Getreide zu untersuchen. Das Ergebnis wird ein modularer Erkennungs-Algorithmus sein, der sich schnell und unkompliziert auf andere Blattkrankheiten anpassen lässt. Von den Partnern INRES und BI-T wird ein Algorithmus erstellt, der auf der Basis von Bildern aus Smartphones Blattkrankheiten an Pflanzen erkennt. Von ZEPP werden Programme erstellt, die solche Algorithmen routinemäßig auf Smatphones und Servern rechnen. ZEPP macht die Tools in der Praxis bekannt und koordiniert das Projekt. ISIP implementiert u. betreibt die Tools auf seinen Internetservern.
