Learning outcomes

On successful completion of this module, students will have:

  • Acquired a good scientific basis in how the main types of coastal and oceanic marine ecosystems work with a view to quantifying the flows of matter.
Introduction to the main principles of operation of pelagic ecosystems (fertilization, development of food chains) within a highly multidisciplinary framework (physics, chemistry and biology).
This module is highly participatory in nature, in conjunction with the theoretical training, and based on specific examples from scientific literature or data collected during boat trips. It thus aims to provide the students with the skills necessary for a study strategy of the marine environment, from sampling to the dissemination of information.


  • Continental shelf ecosystems.
  • Estuaries.
  • Oligotrophic ecosystems.
  • Hydrothermal vent ecosystems.

Practical work:

  • Day trips on board the Albert Lucas (IUEM research vessel) - taking samples in the harbor of Brest.
  • Data analysis in the laboratory.


  • Use of simple biogeochemical models.
  • Data analysis and processing.
Teaching methods Alternation between theory (lectures) and practice (field work).
