The datum was set to WGS84 and the UTM projection (zone 32) was chosen for navigation and display and data acquisition. The time zone was set to the UTC for the whole data acquisition, except for the SBP data that were recorded in UTC+2.
The positioning maps and bathymetric images were done with GMT [Wessel and Smith (1995)].
A WWW server on a Linux Machine was used to share ongoing information and results, including a 30 minutes timed procedure for positioning update and display.
