Prerequisite or corequisite units are presented within each program
Learning unit contents
Carbon, nutrient, greenhouse gases dynamics in marine ecosystems
In the oceans, chemical, biological and physical processes interact in a complex and dependant way. This course specifically aims to give the basis of aquatic chemistry with a particular emphasis on greenhouse gases.
Chapters of the lectures:
1.Foreword
2.Physico-chemical properties of water
3.Seawater composition
4.Salinity as a conservative tracer
5.Ions in seawater
6.Redox reactions - production/destruction of organic matter
7.Green-house gases (CO2, CH4, N2O)
8.Gas exchange accross the air-sea interface
Chapters 1-6 are covered in 6h (2 lectures), chapters 7-8 are covered in 14h (7 lectures)
Marine sediment geochemistry
Study of basic geochemical concepts requested for the interpretation of the geochemical signature of marine sediment records. Examples from literature and from personal proposals.
The cursus is divided in five parts:
- introduction;
- diagenetic processes;
- interstitial waters;
- cycle of metallic elements;
- paleoceanographical tracers
Learning outcomes of the learning unit
Carbon, nutrient, greenhouse gases dynamics in marine ecosystems
Introduction to cycles of organic and inorganic carbon, organic and inorganic nutrients, and greenhouse gases in various marine ecosystems.
Marine sediment geochemistry
Study of chemical processes leading to formation of sedimentary rocks. Analyses of physical and chemical modifications through early diagenesis. Influence of kinetics and bacterial activity.
For more information see the introduction page on MyULiege.
Prerequisite knowledge and skills
Carbon, nutrient, greenhouse gases dynamics in marine ecosystems
Basics in chemistry.
Marine sediment geochemistry
Basic knowledge of mineral chemistry and thermodynamic.
Planned learning activities and teaching methods
Carbon, nutrient, greenhouse gases dynamics in marine ecosystems
20 h of therory, lectures by 3h slots, physically present.
Lectures in English, slides in french.
Marine sediment geochemistry
Analyses and interpretation of geochemical signatures of marine sediments. Treatment and interpretation of geochemical datasets. Use of excel-like software. A personal computer is requested.
Mode of delivery (face to face, distance learning, hybrid learning)
Carbon, nutrient, greenhouse gases dynamics in marine ecosystems
Face-to-face course
Additional information:
20 h of theory by 3 h slots, physically present.
Lectures in English, slides in french.
Marine sediment geochemistry
Blended learning
Further information:
Theory 7 lectures x 2h and practise work 3 x 4h. Lectures and supports are both in English.
Course will be given face-to-face during the first semester. Recorded lectures are available on MyULiege at any time for the students
The practical works will be given on hydrid mode.
Some exercices and data treatments will be done in class under the supervision of the assistant. The participation to those practise works is mandatory
Other practical works (n=3) will be done at home.
1. Reading of imposed articles. The written exam will be based on those articles.
2.Reading of a second imposed article. Personal synthesis under the form of several slides to prepare. Presentation and collective synthesis during the next course.
3. Selection of a paleoceanograpghical geochemical tracer. Synthesis in 5 sllides and presentation in 5 minutes: proxy definition; site description; analytical methods; main results & interpretation; points to underline.
More information on the summary table given on the introduction page on MyULiege.
