Post-meeting summary
Gillian's notes
Participants' slide presentations (name_NAW2_2017.pptx)
Structure of the meeting
Our second meeting will focus on papers planned for the Earth-Science Reviews special section. Presentations relevant to these themes will be given and are allocated 30-min slots. As for the first workshop, presenters are requested to show no more than approximately 10 slides and aim to spend no more than approximately 10 min presenting these slides. Please get straight to your points.
In addition, 30 min of discussion time is allocated to each planned paper and scheduled to follow shortly after the relevant presentation.
As before, presenters are encouraged to bring additional slides, maps, handouts and other display material to distribute and show. 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. As for the last workshop, Oliver Sanford will take charge of the IT.
Any printing required can be done at Durham. Please let us have it in advance to allow time for this. Note that the day before the workshop, Monday 17th April, is a public holiday in the U.K.
Please email Christian Schiffer or Gillian Foulger with comments, corrections, requests or updates.
