| Kurzbeschreibung | 1. Analysis of organic molecules in extracts from soils of different ages in glacial flood fields, in altitudinal gradients from different bedrocks, from sediments, from Cryoconites in glacial ice and from living biofilms in high altitude aquatic ecosystems, and from mineral springs. 2. Analysis of matrix components of the ecosystems: dissolved compounds, minerals, clays, trace metals. | ||||||||||||||||||||||||||||||||||||||
| Lernziel | The student will be able - to design strategies for collecting samples in the field suitable for subsequent analyses in the laboratory - to critically evaluate his/her own analytical data and put it into a scientific context. | ||||||||||||||||||||||||||||||||||||||
| Inhalt | 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. 6. Discussing the results and documenting the outcomes in a scientific report. This 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 and greatly varying salinities and redox conditions. - glacial ice (organics in Cryoconites and in ice) - 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. Procedures for sampling, sample preparation and processing (extraction, analyses) will be defined on the first day of the field course. | ||||||||||||||||||||||||||||||||||||||
| Skript | Procedures for sampling, extraction and analyses will be designed on a special preparation day during the field trips and later in the course of the lab sessions. | ||||||||||||||||||||||||||||||||||||||
| Literatur | Field guides and details about the course logistics will become available to enrolled students on OLAT via Details under https://lms.uzh.ch/url/RepositoryEntry/16318464010?guest=true&lang=de | ||||||||||||||||||||||||||||||||||||||
| Voraussetzungen / Besonderes | The laboratory module (651-4044-01L) takes place as a small research project during the fall semester. Samples collected in the field will be analysed under guidance in the labs of the Biogeosciences Group. The timing of the lab work will be individually adjusted based on the availability of assistants and analytical resources. Students who sign up for both, the field and the lab component, are given priority. There are 10 places available for the project section. The section requires participation on the field trips. It is possible, however, to participate in the field section only without signing up for the project section. At the end of the project section, participants write a report in the style of a scientific paper that contains descriptions of the sampling location, the sample collection and preservation procedures and protocols, description of the analytical methods, the data obtained from analyses of the measured samples and a discussion of the results. Prerequisites: "Geomicrobiology and Biogeochemistry Field Course" (651-4044-02L). The lecture course "651-4004-00L The Carbon Cycle - reduced" is recommended for the project. | ||||||||||||||||||||||||||||||||||||||

| Kurzbeschreibung | Wir studieren Spuren in der Lithosphäre, die Organismen im Verlaufe der Erdgeschichte hinterlassen haben und mineralische Bestandteile, die durch den Einfluss biologischer Prozesse gebildet oder als Quellen von Energie und Nährstoffen genutzt werden. Lebensspuren aus der Vergangenheit werden mit der Entwicklung der Vielfalt von Lebewesen in Zusammenhang gebracht | ||||||||||||||||||||||||||||||||||||||
| Lernziel | Die Lehrveranstaltung befähigt die Studierenden, Fragen über die Entstehung und die Entwicklung von Leben auf der Erde zu stellen, Hypothesen aufzugreifen und neue methodische Ansätze zu entwickeln. Diese werden mit Beobachtungen, Übungen und mathematischen Modellen überprüft. Die geobiologischen Grundlagen ermöglichen den Studierenden, Erkenntnisse, die ihnen in weiterführenden Lehrveranstaltungen vermittelt werden, in Fragestellungen zur Erdgeschichte einzuordnen. Sie lernen, die moderne geologische Umwelt besser zu verstehen und, wo nötig, biogeochemisch fundierte und verantwortungsvolle technische Eingriffe und Schutzmassnahmen zu empfehlen. | ||||||||||||||||||||||||||||||||||||||
| Inhalt | Im Mittelpunkt stehen (a) erdgeschichtlich bedeutsame geobiochemische Zyklen in aquatischen und terrestrischen Ökosystemen, (b) Biosynthesen und katabolische Prozesse, die Leben ermöglichen, (c) die Organismen, die diese regulieren und geochemische Zyklen in Gang halten, und (d) chemische Signale vergangenen Lebens, die in Sedimentgesteinen erhalten geblieben sind. Dazu müssen wir verstehen -- aus welchen Elementen und Molekülen biologische Zellen und deren Bestandteile aufgebaut sind, -- wie Zellen funktionieren und welche Lebensweisen Organismen entwickelt haben, -- wo welche Organismen existieren können und welche Faktoren ihr Vorkommen selektioniert, -- woher biologisch verwertbare Energie stammt und wie sie unter verschiedenen Bedingungen genutzt werden kann, -- wie biologischer Stoffwechsel Umweltveränderungen bewirkt, -- welche Stoffwechselprodukte zu Signalen in Gesteinsarchiven führen können, wie sich Biomoleküle and Elemente nach deren Einlagerung in Sedimenten verhalten, -- wie organische und anorganische Stoffe in der Biosphäre zyklisiert werden und nach welchen grundlegenden Prinzipien biogeochemische Kreisläufe funktionieren, -- wie sich biologische "Innovationen" im Verlaufe der Zeit entwickelt, erhalten, und als Folge von Umweltveränderungen verändert haben. Angewandte Fallstudien, welche die Inhalte ergänzen und illustrieren: -- Wissenschaftliche Anwendungen geobiologischer Erkenntnisse finden wir in der Mikrobiellen Ökologie, der Geochemie, der Paläontologie, der Sedimentologie, der Petrologie, der Ozeanforschung, den Umweltwissenschaften, der Astrobiologie und der Archäologie. -- Praktische Anwendungen aus der Geobiologie fliessen in die Bereiche Altlastensanierung, Schaffung von sicheren Deponien, Grundwasserüberwachung, Abwasserreinigung, Gewinning von und Prospektion für fossile Kohlenstoffreserven, Bodenwiederherstellung, Mineralienabbau und Laugung, Forensik und Geomedizin ein. | ||||||||||||||||||||||||||||||||||||||
| Voraussetzungen / Besonderes | Als integraler Bestandteil der Vorlesung wird eine Exkursion durchgeführt.

| 651-4341-00L | Source to Sink Sedimentary Systems | 3 KP | 2G | T. I. Eglinton, J. Hemingway, L. Bröder, M. Griepentrog | |||||||||||||||||||||||||||||||||||
| Kurzbeschreibung | The transfer and redistribution of mass and chemical elements at the Earth’s surface is controlled by a wide range of processes that will affect the magnitude and nature of fluxes exported from continental fluvial systems. This course addresses the production, transport, and deposition of sediments from source to sink and their interaction with biogeochemical cycles. | ||||||||||||||||||||||||||||||||||||||
| Lernziel | This course aims at integrating different earth science disciplines (geomorphology, geochemistry, and tectonics) to gain a better understanding of the physical and biogeochemical processes at work across the sediment production, routing, and depositional systems. It will provide insight into how it is actually possible to “see a world in a grain of sand” by taking into account the cascade of physical and chemical processes that shaped and modified sediments and chemical elements from their source to their sink. | ||||||||||||||||||||||||||||||||||||||
| Inhalt | Lectures will introduce the main source to sink concepts and cover physical and biogeochemical processes in upland, sediment producing areas (glacial and periglacial processes; mass movements; hillslopes and soil processes/development; critical zone biogeochemical processes). Field excursion (3 days, 30 September -2 October 2022): will cover the upper Rhône from the Rhône glacier to the Rhône delta in Lake Geneva) as small scale source-to-sink system. Practicals comprise (I) a small autonomous project on the Rhône catchment based on samples collected during the field trip and (II) an independent report on how you would design, build, and implement your own source-to-sink study. | ||||||||||||||||||||||||||||||||||||||
| Skript | Lecture notes are provided online during the course. They summarize the current subjects week by week and provide the essential theoretical background. | ||||||||||||||||||||||||||||||||||||||

| Kurzbeschreibung | This course sensitises doctoral students to ethical issues that may occur during their doctorate. After an introduction to ethics and good scientific practice, students are familiarised with resources that can assist them with ethical decision-making. Students get the chance to apply their knowledge in a discipline specific context. | ||||||||||||||||||||||||||||||||||||||
| Lernziel | Doctoral students learn how to identify, analyse and address ethical issues in their own scientific research. In addition, they will reflect on their professional role as scientific researchers. | ||||||||||||||||||||||||||||||||||||||
| Inhalt | Part I The self-paced e-learning course consists of 5 modules: Module 1: Ethics - Introduction to moral theory (with emphasis on practical guidance regarding decision making) Module 2: Ethics in scientific research - Introduction to ethical issues that occur within scientific research (i.e. regarding authorship, cooperation, data use and sharing, and other aspects that are subject to scientific integrity and good scientific practice). Module 3: Collecting resources - A variety of tools and resources that help identify ethical issues are presented and explained Module 4: Setting up a strategy - Example examination of a case regarding its ethical scope (students develop their own strategy to examine situations for their ethical implications). Module 5: Making desicions - Different ways of addressing ethical issues are presented and explained (i.e. how to make hard choices, or solve ethical dilemmas. But also where to seek advice if needed). Part II The second, face-to-face part of this course focuses on discipline-specific aspects. It provides an interactive learning environment. Students get to apply their knowledge, and they are encouraged to reflect on ethical problems and to critically discuss them with fellow doctoral students. | ||||||||||||||||||||||||||||||||||||||
