701-1317-00LGlobal Biogeochemical Cycles and Climate Information 3 KP3GN. Gruber, M. Vogt
KurzbeschreibungThe human-induced emissions of carbon dioxide has led to atmospheric CO2 concentrations that Earth likely has no’t seen for the last 30 million years. This course aims to investigate and understand the impact of humans on Earth's biogeochemical cycles with a focus on the carbon cycle and its interaction with the physical climate system for the past, the present, and the future.
LernzielThis course aims to investigate the nature of the interaction between biogeochemical cycles on land and in the ocean with climate and how this interaction has evolved over time and will change in the future. Students are expected to participate actively in the course, which includes the critical reading of the pertinent literature and class presentations.
InhaltTopics discussed include: The anthropogenic perturbation of the global carbon cycle and climate. Response of land and oceanic ecosystems to past and future global changes; Interactions between biogeochemical cycles on land and in the ocean; Biogeochemical processes controlling carbon dioxide and oxygen in the ocean and atmosphere on time-scales from a few years to a few hundred thousand years.

KurzbeschreibungIn this course, the students acquire skills to implement and test basic numerical models for the simulation of biogeochemistry in aquatic systems using Matlab, to interpret and document model results, and to discuss model limitations. The focus of the course is on practical applications.
LernzielThe aim of this course is to encourage and enable students to develop, test and apply basic numerical models for a range of biogeochemical applications, and to interpret model results.
InhaltNumerical models are useful tools for evaluating processes in complex systems, interpreting observational data, and projecting the response of a system beyond the range of observations. In this course, the students acquire skills to implement and test basic numerical models for the simulation of biogeochemical processes in aquatic systems using Matlab, to interpret and document model results, and to discuss model limitations.
The course includes the following topics:
- Formulation of transport and reaction equations describing aquatic systems
- Numerical recipes (discretization in time and space, finite differences, finite volumes, boundary conditions)
- Implementation of simple models in Matlab (box models, 1D-models, with applications from sediments, lakes, and oceans)
- Techniques for applied modelling & model testing (sensitivity analysis, parameter estimation)
- Interpretation and documentation of model results
- Model applications in current aquatic research (examples from scientific literature)
Modelling techniques will be practised during exercises. A serious effort to solve the exercises is required to pass the course. Furthermore, the students will develop and implement a model for a selected biogeochemical application in groups of two. The students will write a report, which includes a description of their model and its application, as well as a critical interpretation of the model results and a discussion of the limitations of the model. Towards the end of the course, the students will give short presentations of their project work.
SkriptPresentation slides, exercises, and some background material will be provided.
