651-4004-00LOrganic Geochemistry and the Global Carbon Cycle3 KP2GT. I. Eglinton, M. Lupker
KurzbeschreibungThe carbon cycle connects different reservoirs of C, including life on Earth, atmospheric CO2, and economically important geological reserves of C. Much of this C is in reduced (organic) form, and is composed of complex chemical structures that reflect diverse biological activity, processes and transformations.
LernzielA wealth of information is held within the complex organic molecules, both in the context of the contemporary carbon cycle and its links to is other biogeochemical cycles, as well as in relation to Earth's history, the evolution of life and climate on this planet.

In this course we will learn about the role of reduced forms of carbon in the global cycle, how these forms of carbon are produced, move around the planet, and become sequestered in the geological record, and how they can be used to infer biological activity and conditions on this planet in the geologic past. The course encompasses a range of spatial and temporal scales, from molecular to global, and from the contemporary environment to earliest life.
Voraussetzungen / BesonderesThis course and the lecture course "651-4044-00L Geomicrobiology and Biogeochemistry" https://www.olat.uzh.ch/olat/url/RepositoryEntry/14217969664?guest=true&lang=en are good preparations for the combined Field-Lab Course ("651-4044-02 P Geomicrobiology and Biogeochemistry Field Course" and "651-4044-01 P Geomicrobiology and Biogeochemistry Lab Practical").

651-4044-00LGeomicrobiology and Biogeochemistry Information 3 KP2GT. I. Eglinton, T. R. R. Bontognali, C. Vasconcelos
KurzbeschreibungMicroorganisms have helped to shape the Earth over almost 4 billion years making it habitable for higher forms of life. Recent advances in our understanding of how microbial life impacts the Earth have led to a newly evolving field of geomicrobiology and associated biogeochemistry, which links the biosphere with the geosphere.
LernzielThe course aims to provide an introduction to geomicrobiology and to describe how microbial communities have influenced biogeochemical cycles and mineralogical processes through geologic time.

This lecture course is supplemented by an independent field-lab-course from August 29 to September 9. For details see lecture catalog ETHZ 651-4044-02L and ETHZ 651-4044-01L.
InhaltThe lecture course covers the following topics: 1. Microbial properties and diversity, 2. Microbial metabolism that relates to geochemistry, 3. Cell surface reactivity, 4. Sediment biogeochemistry, 5. Biomineral formation in stromatolites, 6. Microbial weathering, 7. Biomarker geochemistry and 8. Microbial life in Earth history. The course will include laboratory practicals in geomicrobiology and geochemistry.
A detailed description of the course layout will become available on OLAT under https://www.olat.uzh.ch/olat/url/RepositoryEntry/14217969664?guest=true&lang=en
at the beginning of January.
SkriptPower point slides will be distributed during the course with recommended reading lists.

KurzbeschreibungContents:
1. Analysis of organic molecules in extracts from soils of different ages in glacial flood fields, in altitudinal gradients and from different bedrocks, and from sediments and living biofilms in high altitude aquatic ecosystems, mineral springs and ice.
2. Analysis of matrix components of the ecosystems: dissolved compounds, minerals, clays, trace components etc.
LernzielThe laboratory module supplements the field trip section. 10 places are reserved for students who also signed up for the field course (651-4044-02L)
Contents:
1. Preparing field work based on research hypotheses.
2. Designing field sampling strategies, proper sampling collection and preservation.
3. Documenting environmental conditions and observations at the sampling sites.
4. Extracting organic molecules from environmental samples with different matrixes.
5. Working under clean conditions and handling samples without contaminating them.
InhaltThis Lab Practical, together with the corresponding Field Trips form part of a continuing "Course Research" unit.
During the field section in the Eastern Alps, we will visit a number of sites that offer
- different bedrocks (dolomite, gneiss, shale, serpentinite, radiolarite, mine tailings) and will study the organics in the soils that formed on them.
- aquatic ecosystems (lakes, rivers, springs) at high altitudes. Organics from pioneering colonizer organisms in lakes formed during the recent retreat of glaciers.
- sediments recently deposited in lakes and flood planes as well as shales that date back to the mesozoic.
The Lab Practical follows immediately after the field work.
SkriptProcedures for sampling, extraction and analyses will be designed on a special preparation day during the field trips.
LiteraturField guides and details about the course logistics will become available to enrolled students on OLAT via Details under https://www.olat.uzh.ch/olat/url/RepositoryEntry/14374567936?guest=true&lang=en
Instructions will be sent in the course of the spring semester to participants who are enrolled for this practical.
