Beschreibung:
Geology / Geomorphology
The students develop a comprehensive understanding of geological processes and formation of seabed features and
bedforms. Seafloor sediment types and corresponding sampling methods are addressed.
Intended learning outcomes
• Describe the structure of the earth and the processes affecting the bathymetry of the oceans.
• Analyse the formation of seafloor features and differentiate between different types.
• Explain various seabed sampling methods.
• Distinguish between different seafloor sediment types and explain sedimentary processes.
Seismics:
Theory of seismic wave propagation: Elastic characteristics of solids, types of seismic waves, attenuation, reflection, refraction, diffraction phenomena.Seismic instrumentation: Energy sources, detectors, recording instruments (analog, digital). Seismic refraction prospecting: theory, field operations, analog and digital data processing, interpretation. Selected case studies. Teaching Method: Taught seminars.
Magnetics and Gravemetry:
Theory of the geomagnetic field: actual field (representation, variations, magnetic storms etc.), model geomagnetic fields (international geomagnetic reference fields). Magnetic survey instrumentation: magnetometers (magnetic field balance, fluxgate, proton, optical pumping magnetometers), moving platform instrumentation. Magnetic data acquisition and reduction. Execution of magnetic surveys, special considerations for moving platforms, numerical reductions, contour maps. Applications: geophysical, wreck search at sea. Gravity survey instrumentation: absolute gravimeters (pendulum, free fall instruments, rise and fall instruments), relative gravimeters (pendulum, spring gravimeters), systems for use on ships and in aircraft. Acquisition and processing of gravity data. Applications in geodesy and geophysics.
