651-3507-00LIntroduction to Oceanography and Hydrogeology3 credits2VD. Vance, M. O. Saar
AbstractThis course is designed to provide an introduction to hydrogeology and oceanography for all Earth Science students at ETH. It provides an overview of the physical controls on water flow in streams, aquifers, and the oceans. It also deals with the basics of groundwater chemistry, biogeochemical cycling in the oceans, the role of the oceans as carbon reservoirs and their dynamic redox state.
ObjectiveTo understand and describe the basic principles of the hydrologic cycle and water flow in streams and aquifers.

To conduct simple calculations of water transfer in streams and aquifers as well as of flood frequencies and magnitudes.

To discuss surface and groundwater as a water resource.

To interpret different ion distributions in aquifers in terms of bacic water chemistry, fluid-mineral reactions, water contamination, and water origin.

To understand the major features of ocean basins and the tectonic controls on their structure.

To identify the major controls on the temperature, salinity and density structure of the oceans.

To describe how these controls interact to drive surface and interior ocean circulation.

To interpret different kinds of element distribution in the oceans in terms of basic chemistry, sinks, sources and internal biogeochemical cycling.

To discuss the cycles of carbon and oxygen in the ocean, with a view to the critical analysis of how the oceans respond to, cause and record the dynamics of these cycles in Earth history.
ContentThis course provides an introduction to oceanography and hydrogeology, with a special focus on the basic physicochemical concepts that control the properties and behaviour of two major reservoirs of water on Earth.

The hydrogeology component will: 1) describe the hydrologic cycle, with a focus on the importance of groundwater to society; introduce the basic physical aspects of groundwater flow, including Darcy's law, hydraulic head, hydraulic conductivity, aquifers; 2) describe the basics of groundwater chemistry, including major ions and mean meteoric water line, basics of groundwater contamination; 3) introduce the interface with the oceans, including hydrothermal circulation at mid-ocean ridges, ocean-water intrusion into groundwater at coasts.

The oceanography component will: 1) provide an overview of the physical circulation of the oceans, including its importance for heat transfer around the surface of the Earth and for climate; 2) describe the basic processes that control the chemistry of the oceans, including its temporal and spatial variability; 3) introduce some simple concepts in biological oceanography, including the dependence of ocean ecology on nutrient distributions. There will be a specific focus on how the physics, chemistry and biology of the ocean might have changed through Earth history, and the impact of oceanic processes on Earth's climate.

2 credits2GM. O. Saar, P. Bayer, M. Brehme
AbstractThe block course focuses on shallow groundwater wells and ground heat exchangers, but also expands the spectrum to include geothermal energy and geostorage potential in Switzerland. The contributions address, among other things, the question of how, with increased use of geothermal resources, conflicts of use due to the growing number of uses can be dealt with.
ObjectiveThe aim of the course is for participants to be able to describe the basic processes of geothermal use and to understand the regulatory framework. They will be able to assess the mutual influence of the uses and know possibilities to take these into account in strategic planning.
