OCB6993 (grduates):Grades will be computed from the results of two midterm tests (15% each) and one final examination (40%). Complementary material not included in the textbook but discussed during the classes or provided as handout or online may be subject of examinations. In addition, graduate students have to prepare and submit on time 3 term papers on topics of marine microbial ecology that will require research into and discussion of original scientific literature beyond the course textbook. Each term paper will count towards 10% of the final grade. Term papers not submitted by their deadline will count as zero points. No extra projects.
