Master seminar 2024 - "Ocean currents and climate change"
each talk will be based on a suggested publication or suggested chapters from an introductory textbook
at least one second paper fitting the talk topic will be integrated into the presentation by the student
30 min presentation, 10-15 minutes discussion
Language: English (German possible)
all participants attend all presentations
all participants contribute to the discussions
Look for a second paper connected to your selection
Discuss with your advisor (either Tobias Zinner or Christian Keil) the literature you plan to use for your presentation soon, well in time before the final preparation of the slide material.
Talk to your advisor at least one more time before the seminar. At this meeting you should go through the final presentation material in time for last changes. Consequently, this should take place shortly before the seminar in October.
