This course is introductory to the concepts and applications of geophysics, after its successful completion the student should be able to:

• Have knowledge of the principles of Geophysics/ applied geophysics
• Solve problems concerning geophysics applying acquired knowledge

Knowledge

Understanding of principles of Solid Earth geophysics and subjects concerning geoelectrics, geomagnetism, gravitational field of the Earth, heat flow in earth’s interior etc In addition, understanding of the theoretical basis/ principles of the main geophysical methods (seismic, geoelectric, geomagnetic, gravity, electromagnetic, GPR)

Skills

• Application of acquired knowledge in understanding/ solving geophysical problems
• Application of acquired knowledge for selecting appropriate geophysical method or combing geophysical methods for solution of problems
• Basic skills in geophysical data processing

Abilities

• Ability to demonstrate knowledge and understanding of essential facts, concepts, principles and theories relating to geophysical theory and problems
• Ability to solve geophysical problems, using acquired knowledge and understanding of geophysics
• Ability of basic processing and interpretation of geophysical data.
• Ability to interact with other students in order to solve geophysical problems
• Ability to work in a team

By the end of this course the student will, furthermore, have developed the following skills (general abilities):

• Ability to apply acquired knowledge and understanding to the solution of problems related to geophysical data processing
• Ability to solve problems.
• Ability to prepare and execute searching, analysis and synthesis of data and related information
• Ability to interact with others in problem solving

• Use of Information and Communication Technologies (ICTs) in teaching.
• The lectures content of the course, for each chapter, are uploaded in the eclass platform. The same is done for laboratory exercises together with the appropriate presentation. Interaction with students is done through email and the eclass platform as well.

The assessment is done in the following way:

• Written examination after the end of the semester which includes
• Short answer theory based questions
• Essay answer questions
• Assessment questions
• Problem solving questions
