  • (2) Learning Outcomes
  • Learning Outcomes

The purpose of this specific course is to acquaint senior undergraduate students with mechanisms and processes that transfer information and cause mass and energy flows on the planet, directly affecting the evolution of not only the physical but also the biochemical characteristics of the marine ecosystem.

Successful completion of the course equips the student with a deeper knowledge of the processes that govern the Ocean variability, and the necessary tools to be able to recognize and study more complex phenomena that are affected. 

The successful completion of the course provides the student with the background to

(a) get familiar with and understand the dynamics of, at least at a qualitative level, the different waves and mixing processes that take place in the sea, over the full range of spatiotemporal scales;

(b) to identify dominant mechanisms according to their recorded characteristics 

(c) be able to synthesize information and predict the effects of these mechanisms on the marine environment

(d) to be able to handle appropriate tools for the analysis and simulation of these mechanisms.

  • General Competences

Search for, analysis and synthesis of data and information, with the use of the necessary technology 
Understanding of natural environmental processes
Use of computer programming for the simulation of processes and their impacts
Working independently 
Team work
Working in an international environment 
Working in an interdisciplinary environment 
Production of new research ideas  
Respect for the natural environment
