Biogeochemie

Die Erde im Wandel der Zeit: vom Ursprung bis ins Anthropozän

Biogeochemie ist eine interdisziplinäre Systemwissenschaft, deren Themenkreis alle fünf geochemischen Sphären umfasst: Biosphäre, Pedosphäre, Hydrosphäre, Atmosphäre und Lithosphäre.

Schgemne

E. Gorham beschreibt die Biogeochemie wie folgt ...
Biogeochemistry deals with control of the concentrations and cycling of elements in and above the earth’s crust by the synthesis, death and decomposition of organisms. The term was coined by Vernadsky (1926) (...). Biogeochemistry represents a very gradual coalescence and eventual synthesis of three diverse disciplines into a recognized branch of science. In it the most fundamental aspects of knowledge of the planet Earth are being studied by scientists at the same time, and in the same way, that they seek a better understanding of extremely important practical problems. Most notable among such problems are those caused by human manipulation of biogeochemical cycles on nature’s own scale. The challenge that faces humanity is nothing less than the maintenance of the balance of nature represented by those cycles, which will require a greatly improved understanding of planetary biogeochemistry.” Gorham, E., 1991. Biogeochemistry: its origins and development. Biogeochemistry 

 

Die Biogeochemie steht damit im engen Zusammenhang mit dem Begriff des Anthropozäns welches den Menschen als Faktor versteht, der die geologischen, biologischen und atmosphärischen Prozesse auf der Erde unwiderbringlich verändert. Damit wird der Mensch zum konkret Verantwortlichen für die weitere Entwicklung unseres Planeten. Geprägt wurde der Begriff vom Atmosphärenchemiker und Nobelpreisträger Paul Crutzen. Die Diskussion um das "Anthropozän"  als neue geologische Epoche wird im Forschungsmagazin Ruperto Carola (Ausgabe 15, Dezember 2019) (Link hier) und im Buchkapitel "Anthropozän" (Link hier) erschienen in Umwelt interdisziplinär - Grundlagen-Konzepte-Handlungsfelder, näher erläutert.

 

Für biogeochemische Fragestellungen haben sich stabile Isotope als bewährte Hilfsmittel etabliert. Sie dienen als Indikatoren für (bio)chemische Reaktionen und sind fähig, Schwankungen der Umwelt sowie des Klimas zu reflektieren. In unserer Forschungsgruppe liegt der Schwerpunkt auf der Messung und Anwendung stabiler Isotope in zahlreichen Feldern der Biogeochemie sowie benachbarten Disziplinen (siehe nachfolgende Abbildung).

Die Forschungsgruppe Biogeochemie erforscht die Bildung klimarelevanter Substanzen und ihren Lebenszyklus. Der Forschungsschwerpunkt liegt auf den Klimagasen Kohlendioxid, Methan und Lachgas und deren Beitrag zum Treibhauseffekt beziehungsweise zur Ozonzerstörung. Zudem untersucht die Forschungsgruppe anhand von Baumringen und Sedimenten Veränderungen des Klimas in der Vergangenheit. Ein weiterer Schwerpunkt ist die Entwicklung und Anwendung analytischer Messmethoden zur Bestimmung der isotopischen Zusammensetzung von Klimagasen. Darüber hinaus werden optische Messtechniken zur Isotopenbestimmung von Methan und Kohlendioxid in Biogasreaktoren entwickelt und getestet. Schließlich werden auch Methoden zur Herkunfts- und Echtheitsprüfung von Lebensmitteln in der Arbeitsgruppe entwickelt.
