Structure of the meeting
This agenda is a draft that will be updated in response to participant requests, suggestions and any late changes in the participant list.
Each presenter is allocated a 30-min slot. Presenters are requested to show no more than approximately 10 slides and aim to spend no more than approximately 10 min presenting these slides. Thus, presenters must get straight to the point. All meeting participants will be familiar with North Atlantic history, structure and tectonics and thus scene-setting introductory slides can be kept to a minimum.
The remaining 20 min in each 30-min slot will comprise open discussion. If any participant requires more clarification of the preceding presentation, they can request it as part of this discussion.
Presenters are encouraged to bring additional slides, maps, handouts and other display material to distribute and show during the 20-min discussion periods and the longer time-tabled discussion periods. Presenters may show “mini-presentations” as contributions to these discussions, comprising no more than 3 slides to illustrate their points. Additional slides of this sort must be loaded onto the meeting laptop beforehand.
Any printing required can be done at Durham. If material is voluminous, please let us have it in advance to allow time for this.
Please email Alex Peace at a.l.peace@durham.ac.uk with any comments, corrections, requests or updates.
