Master seminar 2024 - "Ocean currents and climate change"

  1. Look for a second paper connected to your selection
  2. 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.
  3. 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.
