3D post-overwash fieldwork

Conversely to the previous fieldwork, on January 30 overwash maximum intrusion on the barrier top was very easy to follow.

At the end of this fieldwork we computed the distance that we make holding the GPS antenna and discovered that in a 2 km coastal stretch we walk 14 km!!!!

We had to wait until February 4th to do the bathymetric survey. Our experienced skipper advised us to postpone the survey because of the waves.

This set of data is very good as there is a high confidence on the overwash intrusion and also there is a good match between the lowest points on the topographic survey and the highest points on the bathymetric survey.
