| Course objective :
| The main aim of this course is to learn how to conceptualize, parameterize and implement mathematical models of marine biogeochemical processes | |
|  | | |
| Prerequisites :
| None. The mathematics used will be quiet elementary | |
|  | | |
| Workshops :
| The half part of the time will be devoted to the implementation of very simple examples in order to get familliar with models implementation | |
