3. How paraglacial coasts evolved
under climate change?

4. Are paraglaciation and paraglacial processes
more efficient than glaciation and glacial processes for polar landscapes evolution?

13. Field campaign 2017
Objectives: data acquisition for the three sites (cliff, sandy coasts, lateral moraine)
People involved: the same 5 people than in 2016, in two teams
Marine Bourriquen, Agnès Baltzer and Jérôme Fournier: 10 to 24 August
Marine Bourriquen, Stéphane Costa and Denis Mercier: 24 August – 4 September
Needs on the field:
A boat:
Jean Floch for sonar data acquisition along the sandy coast (3 or 4 days)
an other boat for the other sites
weapons and safety equipment
