KurzbeschreibungBiomineralogy: Microbes dissolving/forming minerals
Geo-Ecology: Geochemical, hydrologic, atmospheric interactions
Geo-Microbiology: Pioneering organisms in "new" habitats in glacial retreat areas
Geochemistry: Carbon sequestration in glacial flood plains, soil formation on different bedrocks, nutrient scavenging in low-nutrient lakes
Life Styles: Physiological adaptation to extreme conditions
LernzielIllustrating basic geological, chemical and geo-biological topics under natural conditions and relating them to past, present and future global environmental conditions in high mountain habitats.
Each course participant focuses on a scientific question related to one of the course topics, searches for details in the literature and presents a short summary of his / her course research on the last day of the course.

Didactic Approach: Preparation lectures, investigation of field sites, sampling and sample preservation and follow-up analyses for the lab module (651-4044-01L), studying papers, exercises on concept formulation, ecosystem modeling, presentation of field results.
The preparation for the fieldwork is designed as a partial distance-learning course via the internet. Field Guides along with other course material can be viewed before the field course. Detailed introduction to the topics takes place during the course week. Students will need to complete a variety of assignments and participate at discussion forums on OLAT before and during the field course.
InhaltThe field course (651-4044-02L) will take place from September 3 to September 8 in the Biogeoscience Arena Silvretta. It will be followed by a semester project in the laboratory (independent sign-up under 651-4044-01L).
Sites visited in the Biogeoscience Arena Silvretta depends on the weather, accessibility in case of early snow and the time. Selection of topics (not all sites listed will be visited every year):
1. Biogeochemical processes in rock weathering and the formation of minerals: Gonzen, former iron mine; Alvaneu, sulfur springs. Chemical and microbially mediated transformation of carbonates and gypsum: Albula valley region.
2. Geomicrobiology and hydrogeochemistry in thermal spring (Tamina gorge, Pfäffers) and cold water mineral springs of the Lower Engadin Window: Highly mineralized spring water emerging from low grade metamorphic rocks (Bündner shist) by ion exchange processes and release of rock interstitial fluids.
3. Geochemical nutrient sequestration in high mountain lakes and in snow and ice: Joeri lake area (Silvretta gneiss).
4. Coupled processes in biogeochemical iron, manganese and phosphorus cycling: Jöri lake XIII.
5. Primary processes in soil and peat formation (inorganic to organic transition, carbon sequestration) and microbial colonization: Glacial retreat flood plains, early vegetation on delta and moraine soils.
6. Life styles under extreme conditions: Microorganisms and small invertebrates in ice (Cryoconite holes, Silvretta glacier), snow and highly mineralized spring water.
7. Formation and weathering of serpentinite (Totalp), effects on soil formation and on vegetation.
8. Economic aspects of geo-hydrology: mineral water market, wellness tourism and geo-medical aspects.
SkriptThe new field guides and details about the course logistics will become available on OLAT in June via Details under
Instructions will be sent during the spring semester to participants who are enrolled for this course in "MyStudies".
LiteraturLecture slides and literature references are available on the corresponding OLAT site: Details under
Voraussetzungen / BesonderesSites visited and course contents can vary from year to year depending on interest, accessibility and weather conditions.
Field-work can last up to 8 hours daily and will take place at altitudes up to 3000m. This requires endurance and a certain physical fitness. Participants need to be prepared.
Target Groups: Field course and semester project work for the upper level Bachelor curriculum and for Master students.

This field course is coupled to a semester project work "651-4044-01 P Geomicrobiology and Biogeochemistry Lab Practical", when samples collected during the field work will be analyzed. Students who sign up for both, the field and the lab component, have priority. It is possible, however, to participate at the field section only.
The lecture course "651-4004-00L Organic Geochemistry and the Global Carbon Cycle" is a good preparations for the combined Field-Lab Course.

Students registering for the course confirm having read and accepted the terms and conditions for excursions and field courses of D-ERDW
651-4226-00LGeochemical and Isotopic Tracers of the Earth System
Findet dieses Semester nicht statt.
3 KP2VD. Vance
KurzbeschreibungThis unit discusses the geochemical approaches used to understand the dynamics of the surface Earth, now and in the past. Emphasis is placed on gaining a basic understanding of how the tracers work, e.g. on the modern Earth. Case studies will be used to appreciate what we can learn about the past, in particular the major changes that the surface Earth system has undergone over Earth history.
LernzielThis unit is designed with the particular aim of providing a firm grounding in the geochemical methods used to observe and trace the Earth System, now and in the past. The approach in lectures will be the pursuit of a sound understanding of the controlling physical and chemical factors of each method, to encourage students to think about their application and interpretation from first principles. Exercises will provide an opportunity to analyse real data, to understand their meaning, and to quantitatively interpret them in the context of simple box models.
InhaltMost of the important geochemical and isotopic methods used to study the surface Earth will be covered, including: tracing the hydrological cycle using stable isotopes , geochemical and isotopic tracing of the carbon cycle, the chemistry of aerosols in the atmosphere, using boron isotopes to understand the oceanic carbonate system, using radiogenic isotopes as surface Earth tracers (including U-series, Sr-Nd-Pb etc), the silica cycle at the surface Earth (including silicon isotopes), trace metals and their isotopes (focusing on surface Earth redox).

Real data will be woven through all of these but case studies using geochemical data will come from e.g. the
Quaternary (ice cores, ocean sediments and speleothems), the history of Cenozoic CO2 , Mesozoic OAEs, the early oxygenation of the Earth.
SkriptSlides of lectures will be available.
