Karst and global carbon cycle

This course is part of the programme:
Karstology (Third Level)

Objectives and competences

Student will be familiar with global geochemical and biochemical carbon cycle and with role of karstification. He/she will be learnt about carbon fluxes on karst, loops that connect system components, role of karst as source, sink or reservoir of carbon, methodology of carbon flux measurements on karst surface and underground, impact of karstification on carbon isotopic ratio in water and cave atmosphere as well as consequences of climatic changes on carbon cycling on karst.

With acquired knowledge, student will be competent in the field of knowing state of the art in carbon cycle research, he/she will be skilled to measure carbon fluxes on karst areas and skilled to evaluate future impact of climate changes on karst carbon cycling

Prerequisites

Content (Syllabus outline)

  • Biochemical and geochemical global carbon cycle
  • Long-term and short-term carbon cycle – loops
  • Role and importance of karst processes (dissolution and sinter/tufa deposition) in carbon cycling
  • Quantitative physicochemical measurements of carbon fluxes on karst surface and underground
  • Carbon cycling and carbon isotopic ratio
  • Global and karstic aspect of carbon sources, sinks/storage/sequestration and reservoirs
  • Natural and anthropogenic impact on carbon cycle
  • Climate changes and carbon cycling on karst

Intended learning outcomes

Student will be able to perform his/her further fundamental and aplied research on carbon cycling on karst, he/she will be able to apply general measurement concepts on other similar research and to criticaly evaluate findings of related scientific disciplines.

Assessment

Oral exam (80 %) – it is intended to evaluate the knowledge attained by a student through lectures as well as his capacity of understanding, critical evaluation, articulation and expression of acquired knowledge. Condition to take examination is seminar work (20 %) on carbon cycling on karst or approach to carbon flux measurements.
