651-4049-00L	Conceptual and Quantitative Methods in Geochemistry Der erfolgreiche Abschluss des Bachelor-Kurses Geochemie (651-3400-00L) ist für diesen Kurs Voraussetzung.	W+	3 KP	2G	O. Bachmann, D. Vance, G. De Souza, A. Hunt, J. Leuthold
Kurzbeschreibung	This course will introduce some of the main quantitative methods available for the quantitative treatment of geochemical data, as well as the main modelling tools. Emphasis will both be on conceptual understanding of these methods as well as on their practical application, using key software packages to analyse real geochemical datasets.
Lernziel	Development of a basic knowledge and understanding of the main tools available for the quantitative analysis of geochemical data.
Inhalt	The following approaches will be discussed in detail: major and trace element modelling of magmas, with application to igneous systems; methods and statistics for calculation of isochrons and model ages; reservoir dynamics and one-dimensional modelling of ocean chemistry; modelling speciation in aqueous (hydrothermal, fresh water sea water) fluids. We will discuss how these methods are applied in a range of Earth Science fields, from cosmochemistry, through mantle and crustal geochemistry, volcanology and igneous petrology, to chemical oceanography. A special emphasis will be put on dealing with geochemical problems through modeling. Where relevant, software packages will be introduced and applied to real geochemical data.
Skript	Slides of lectures will be available.

651-4227-00L	Planetary Geochemistry	W+	3 KP	2G	M. Schönbächler, H. Busemann, A. Hunt
Kurzbeschreibung	Formation and evolution of the solar system from a geochemical perspective
Lernziel	To understand the formation and evolution of the solar system and its planets from a geochemical perspective
Inhalt	The Sun and solid objects in the solar system (planets, comets, asteroids, meteorites, interplanetary dust) are discussed from a geochemical perspective. What does their present-day composition tell us about the origin, formation and evolution of the solar system? The lectures introduce the basics of the terrestrial and giant planets, comets and asteroids, gained from modern space missions and the study of extraterrestrial materials. The chemical and isotopic composition of meteorites, being the most primitive material available for study, is a further major topic.

651-4057-00L	Climate History and Palaeoclimatology	W	3 KP	2G	H. Stoll, A. Fernandez Bremer, I. Hernández Almeida, L. M. Mejía Ramírez
Kurzbeschreibung	Climate history and paleoclimatology explores how the major features of the earth's climate system have varied in the past, and the driving forces and feedbacks for these changes. The major topics include the earth's CO2 concentration and mean temperature, the size and stability of ice sheets and sea level, the amount and distribution of precipitation, and the ocean heat transport.
Lernziel	The student will be able to describe the factors that regulate the earth's mean temperature and the distribution of different climates over the earth. Students will be able to use and understand the construction of simple quantitative models of the Earth's carbon cycle and temperature in Excel, to solve problems from the long term balancing of sinks and sources of carbon, to the Anthropogenic carbon cycle changes of the Anthropocene. Students will be able to interpret evidence of past climate changes from the main climate indicators or proxies recovered in geological records. Students will be able to use data from climate proxies to test if a given hypothesized mechanism for the climate change is supported or refuted. Students will be able to compare the magnitudes and rates of past changes in the carbon cycle, ice sheets, hydrological cycle, and ocean circulation, with predictions for climate changes over the next century to millennia.
Inhalt	1. Overview of elements of the climate system and earth energy balance 2. The Carbon cycle - long and short term regulation and feedbacks of atmospheric CO2. What regulates atmospheric CO2 over long tectonic timescales of millions to tens of millions of years? What are the drivers and feedbacks of transient perturbations like at the latest Palocene? What drives CO2 variations over glacial cycles and what drives it in the Anthropocene? 3. Ice sheets and sea level - What do expansionist glaciers want? What is the natural range of variation in the earth's ice sheets and the consequent effect on sea level? How do cyclic variations in the earth's orbit affect the size of ice sheets under modern climate and under past warmer climates? What conditions the mean size and stability or fragility of the large polar ice caps and is their evidence that they have dynamic behavior? What rates and magnitudes of sea level change have accompanied past ice sheet variations? When is the most recent time of sea level higher than modern, and by how much? What lessons do these have for the future? 4. Atmospheric circulation and variations in the earth's hydrological cycle - How variable are the earth's precipitation regimes? How large are the orbital scale variations in global monsoon systems? Will mean climate change El Nino frequency and intensity? What factors drive change in mid and high-latitude precipitation systems? Is there evidence that changes in water availability have played a role in the rise, demise, or dispersion of past civilizations? 5. The Ocean heat transport - How stable or fragile is the ocean heat conveyor, past and present? When did modern deepwater circulation develop? Will Greenland melting and shifts in precipitation bands, cause the North Atlantic Overturning Circulation to collapse? When and why has this happened before?
