Oral presentations are organized in sessions scheduled in specific lecture rooms, indicated in the programme. The oral sessions are scheduled in four 105-minute time blocks per day. Please note that the duration assigned to your oral presentation includes 3 minutes for questions and discussion and for change-over to the next speaker (e.g. a 15-minute talk should be 12 minutes of presentation + 3 minutes of discussion). All lecture rooms offer 16:9 projection. The classic 4:3 format is also supported.

It is strictly prohibited to take photos of any scientific material without the explicit permission from the authors. Authors are therefore asked to indicate explicitly on the first slide of their presentation whether they forbid or allow photography of their work. Please download EGU's official graphics for inclusion in your presentation: photography encouraged | photography NOT allowed

The oral presentations are not organized centrally. Therefore, authors are kindly asked to upload their presentations directly in the respective lecture room 30 minutes prior to the time block of the session. A lecture room assistant will be available if you need help. When producing PowerPoint files, we recommend embedding all used fonts in order to guarantee a smooth presentation.

Lecture room equipment

  • Video projector
  • Notebook for the upload of presentations (USB flash drive only), including Internet connection
  • Presenter panel to connect a personal notebook to the projector via a switch (VGA and HDMI including power supply)
  • For pointing, the vast majority of lecture rooms have a wireless mouse with an enlarged, green pointer. This can be much better seen by the audience than classical laser pointers. The mouse is also your slide switch. Lecture rooms with single projection offer Bluetooth presenters in addition. Such presenters are also your device for switching slides in the few rooms without a mouse
  • Presentation timer with displays for presenter and chairperson
  • Speaker microphone (necklace) and lectern microphone in rooms with lecterns
  • Wireless handheld discussion microphones (larger rooms only)
  • PC sound is not a standard feature in the lecture rooms but will be provided when needed. Please inform the conference assistant in your lecture room when you upload your presentation
  • We offer step stools at lecterns in lecture rooms.

  • Windows 10;
  • MS Office (Power Point, Word);
  • LibreOffice;
  • Adobe Reader;
  • GPL Ghostscript;
  • GSview;

Presentation tips

  • Time your presentation so that you will have 3 minutes of your allocated time left for questions and discussion and for change-over to the next speaker
  • Use font sizes that are large enough to be read from some distance, this should also apply to labels on figure axes
  • Please consider adding a one-sentence summary of each slide at the bottom to help audience follow the presentation
  • Avoid the rainbow colour scale since it is not distinguishable for everyone
  • Where available, use the mouse for pointing as this provides best visibility
  • Please use the microphone
  • Repeat audience questions (when these were not posed using a microphone) so everyone will be able to follow the discussion

Please be advised that beginning in 2020, EGU will stream the audio signal from all lecture rooms to allow attendees to connect their hearing-aid devices to a smartphone to receive the audio stream. Union Symposia, Great Debates, and some Science-and-Society sessions are web-streamed and archived online.

Oral no-shows

Inclusion of your abstract in the conference programme obliges you or one of your co-authors to present your contribution at the time and in the manner indicated. If you already know that your contribution will not be presented, you are asked to withdraw your abstract as soon as possible.

At the conference, missing presentations are categorized as no-shows if the abstract has not been withdrawn by the time of the presentation as given in the programme. Such no-shows will be recorded and conveners will be informed after the conference. No-show authors will be asked for reasons. Without appropriate reasons, these abstracts and their PDF files will be removed from the conference website and a message "withdrawn after no-show" is added to the presentation slot in the online programme.
