Learning outcomes of the course :
|
| The main aim of this course is to learn how to conceptualize, parameterize and implement mathematical models of marine biogeochemical processes |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| None. The mathematics used will be quiet elementary |
|
Planned learning activities and teaching methods :
|
| The half part of the time will be devoted to the implementation of very simple examples in order to get familliar with models implementation |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| 1.5 ECTS : theory
1.5 ECTS : Exercises |
|
