| Course contents : | - The pelagic ecosystem inhabits all the parts of the seas and ocean other than coast and bottom. The cursus develop a multidisciplinary study method of that ecosystem. The methodology is applied to the Mediterranean, the Austral Ocean and the north Sea.
- A general view of the pelagic diversity and sampling and analysis methods are given thanks to simple taxonomic and analytic tools. The relations between key-species and habitat will be presented.
- The global functioning of some key oceanic ecosystems is developped on the base of function processes developped previously in the cursus of Biological Oceanography and Marine Ecology.
- Elements of Fisheries Oceanography allows to determine the link between fish population, fisheries, plankton production and ocean circulation.
- The impacts of environmental changes on pelagic ecosystem are developed.
|
|
| Course objective : | To develop a practical knowledge of pelagic habitat and the understanding of the impact of the hydrology, the circulation, the climate and the Man on its functionning |
|
| Prerequisites : | A good basic knowledge on processes in Biological Oceanology and Marine Ecology |
|
| Workshops : | - Technics of pelagic habitat are studied individually in the laboratory (plankton net; identification and counting with video-microscope; pigment analysis by fluorescence, sectrophotometry and HPLC; video camera; light trap).
- A field stage (station STARESO of the University of Liège- Calvi Corsica) is used to apply the concepts to a practical study of the distribution of pelagic organisms in relation to the physiscal and chemical structure of the water masses. |
|
| Organization : | One half day per week during second quadrimester |
|
| Written notes : | Written cursus (in french), power point presentation, and a data base on the diversity and technics. |
|
| Assessment : | Presentation of a 15 min talk on a pelagic system at the choice of the student. Oral and practical examination on the cursus. |
