LEARNING OUTCOMES
Upon successful completion of the course, students are expected to:
- Recognize the different methods of subsoil geophysical research (surveys) currently used with examples from their application to tracking various objectives of excavation interest (archeometry), technical interest (design of technical projects) as well as in the investigation of complex geodetic and territorial structures formations for hydrological applications
- Distinguish between design requirements and expected geophysical results in the context of tackling a geological problem in relation to geophysical properties of the “target” and the selection of the appropriate method.
- Calculate the “resolution” of geophysical methods but also the way with which the measurements are taken.
- Combine the results of geophysical and geological data and evaluate results.
- Compose high-resolution subsoil maps using advanced methods of graphic editing
- Support decision-making of excavation or technical interest using soundings’ results
- Know the basic geophysical organology and field measurement techniques
General Competences
- Search, analyze and synthesize data and information, using both necessary technologies
- Project planning & management
- Autonomous work in an interdisciplinary environment
- Promotion of free, creative and inductive thinking
- Decision making
- Time management – Working with deadlines
SYLLABUS
- Introduction – Basic concepts of geophysics.

- Geoelectric surveys (Introduction, theoretical foundation), Vertical and lateral electrical resistivity distribution, geoelectric tomography. Equipment. Measurements, processing, interpretation and evaluation. Applications in geoenvironmental, geotechnical, etc. problems.
- Electromagnetic (EM) observations (Introduction, Theoretical Foundation, Propagation and electromagnetic field attenuation). EM Controlled Source Methods, horizontal Frequency Field Imaging (VLF), Vertical Time Field Imaging (TDEM), Ground penetration radar (GPR). Measurements, processing, interpretation and evaluation. Examples and applications.
- Illustrations of high resolution results with advanced processing graphic methods
STUDENT PERFORMANCE EVALUATION
Assessment language: Greek (English for ERASMUS students upon request)
Performance evaluation method:
• Final Written Exam (50% of the final grade) of graded difficulty, which include short-answer questions, open-ended questions and solving simple problems.
• Evaluation of laboratory work (30% of the final grade) from fieldwork
• Evaluation of project (20% of the final grade)
The evaluation criteria have been presented to the students before the final examination. Students can see their evaluation upon request and receive clarifications on their grades.
