- narrow down a research question.
- identify relevant literature to address the research question.
- concisely summarise and critically evaluate their findings.
- formulate key outstanding questions.
ContentEach student is expected to write a paper with a length of approximately 15-20 pages. The students can choose from a list of topics prepared by the tutors, but the final topic will be determined based on a balance of choice and availability. The students will be guided and advised by their tutors throughout the course.

The paper itself should contain the following elements:
- Motivation and context of the given topic (25%)
- Concise presentation and critical evaluation of the state of the science (50%)
- Identification of open questions and perhaps outline of opportunities for research (25%)

In addition, the accurate use of citations, attribution of ideas, and the judicious use of figures, tables, equations and references are critical components of a successful paper. Specialised knowledge is not expected, nor required; neither is new research.

651-4004-00LThe Global Carbon Cycle - ReducedW3 credits2GT. I. Eglinton, L. Bröder, R. G. Hilton
AbstractThe 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.
ObjectiveA 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.
Prerequisites / NoticeThis course is good preparation 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"
651-4056-00LLimnogeologyW3 credits2GN. Dubois, A. Gilli, K. Kremer
AbstractThis course links lakes, their subsurface and their environment. It will be discussed how lake sediments record past environmental changes (e.g. climate, human impact, natural hazards) and how lake sediments can be used to reconstruct these changes. Emphasis is also given on the modern limnologic processes essential in interpreting the fossil record. Field and laboratory work is foreseen.
ObjectiveStudents are able to
- explain and discuss the role of lake sediments as archives of environmental change.
- plan an own limnogeologic campaign, i.e. finding, recovering, analyzing and interpreting the sedimentary lake archive to solve a particular scientific question.
- examine the complexity of a lake system with all its connection to the environment.
- relate subaerial processes with subaquatic processes.
- identify processes around and in lakes causing natural hazards.
ContentContent of the course:
Introduction - Lakes, the small oceans
History of Limnogeology.
Limnogeologic campaigns
The water column: Aquatic physics (currents, waves, oscillations, etc.).
Sediments caught in the water: sediment traps
Geophysical survey methods (multibeam bathymetry, seismics)
Large open perialpine lakes.
Laminations in lake sediments: Clastic vs. biochemical varves.
Hydrologically closed lake systems
Chronostratigraphic dating of lake sediments
Lake sediments as proxies for climate change
Lake sediments as recorder of anthropogenic impact

The class includes 2 lectures as field work on Lake Zurich.
Introduction to themes of Lake Zurich field work.
Limnogeological methods on the lake and in the laboratory: various sampling and surveying techniques (water analysis, seismic surveying, sediment coring, laboratory analyses).
Seismic-to-core correlation and interpretation
Lecture notesWill be distributed in each class unit.
LiteratureWill be distributed in each class unit.
Prerequisites / NoticeCredit points and grade will be given based on a individually written report about the project and a group presentation.
